1. PURPOSE.
This manual provides a means of classifying en- listed military occupational specialists. In addition to this manual, classification and assignment mate- rial appearing herein and affecting the AAF has been extracted and published in AAF Manual 35—1, Military Personnel Classification and Duty Assign- ment. Reference to that manual should be made in connection with Army Air Forces classification and assignment procedures. Proper classification of enlisted men will facilitate the —
a. Conservation of available skills through maxi- mum utilization of physical capacity, leadership qualities, experience, education, training, skills, and aptitudes.
b. Construction and development of Tables of Organization and other personnel manning tables with respect to the kinds of military occupational specialists needed by a unit to perform its mission.
c. Requisition and assignment of enlisted men qualified to meet the requirements of a military assignment.
d. Selection of enlisted personnel for retraining or vocational rehabilitation in preparation for con- tinuation of service in the Army or for return to gainful civilian employment.
e. Separation of individuals from military serv- ice and rational demobilization to achieve fullest utilization of military occupational training and experience upon return to civilian life.

2. DEFINITION OF A MILITARY OCCUPA- TIONAL SPECIALTY (MOS).
a. In determining an MOS the general principle followed throughout is that duty assignments which basically involve the same kind of training, expe- rience, techniques, abilities, and the same relative degree of physical capacity on the part of a soldier are classified together under a broad MOS. A duty assignment which is so specialized as to prevent grouping is recognized as an individual MOS. Ex- amples, the job description of a Clerk-Typist (SSN 405) represents a broad classification and such duty assignments as Company Clerk, Typist, and Chaplain's Assistant fall within the area of skills which the MOS of Clerk-Typist represents. How- ever, the job description of- an Orthopedic Mechanic (SSN 366) represents a specialized duty assign- ment not susceptible to grouping and is an MOS in itself.
b. An MOS, therefore, is the term used to iden- tify an Army job which comprises one or more related duties and responsibilities normally requir- ing special knowledge and skills acquired through civilian training and experience supplemented by military training and experience, or military train- ing and experience only.
c. The specification serial number (SSN) is a numerical code assigned to an MOS for control, reporting, and requisitioning purposes.
1
MILITARY OCCUPATIONAL CLASSIFICATION OF ENLISTED PERSONNEL
3. RELATIONSHIP OF AN MOS TO TA- BLES OF ORGANIZATION.
Tables of Organization and Equipment and other Tables of Distribution may list any of the duty titles common to an MOS. Example, such duty assign- ments as Company Clerk, Typist, and Chaplain's Assistant can be performed by one qualified in the MOS of Clerk-Typist (SSN 405). Any or all of the. above titles may appear in Tables of Organization. In each case, however, the SSN listed would be 405 since this is the numerical code which controls the authorized duty titles representing assignments which fall within the area of skills represented by the MOS of Clerk-Typist.
4. RELATIONSHIP OF A MILITARY OCCU- PATIONAL SPECIALTY TO THE ARMS AND .SERVICES.
a. In many cases the same MOS is required by more than one arm or service and it is customary for the arms and services involved to train and de- velop the required specialist, through school or unit training or both, usually for assignment within their respective organizations. The same training, tech- niques, and abilities and the same kind of work are required of the specialist, basically, regardless of the arm or service in which he is developed. How- ever, because of differences in equipment, tactics, -operations, physical capacities, etc., which exist in the various arms and services, it is indicated that an MOS should always be associated with the arm or service which developed it. In other words, the iden- tity of the arm or service which develops an MOS is an integral part of that MOS and should be rec- ognized as such.
b. The above factors should be considered in all placement and replacement matters. For example, a Field Artillery trained Tank Mechanic, Minor Maintenance (SSN 660) should be assigned to a Field Artillery unit whereas an Armored Command trained Tank Mechanic, JMinor Maintenance should be assigned to an Armored unit. However, where exigencies of the situation make this impracticable every attempt will be made to assign specialists to closely allied assignments in the order of their relationship to one another. Example, where a Field Artillery trained Tank Mechanic, Minor Mainte- nance (SSN 660) is required and is not available, the same kind of specialist who is either Tank De- stroyer or Armored Command trained should be assigned because the same kind of work is required of these specialists, basically. The differences which exist as to type of equipment, tactics, etc., of an organization can be absorbed by the specialist. Sec- tions II and IV of this manual should be studied
in connection with further determinations of this nature.
5. DETERMINATION OF SOLDIER'S MILI- TARY OCCUPATIONAL SPECIALTY (MOS).
a. An MOS will be assigned an enlisted man only as follows:
(1) Through the successful completion of a course of training at a training center or service school, if it has been determined by proper authority that the course qualifies a graduate in a specialty. Determination by proper au- thority shall include clearance of military training programs with The Adjutant Gen- eral's office (Classification and Replacement Branch) for determination of the appropriate MOS to be assigned to graduates of various courses.
(2) Through satisfactory performance of the duties and responsibilities of a military occupational specialty in a unit or installation for a period of 60 days.
(3) Through civilian experience, when of such na- ture as to be a practical counterpart of an MOS and when proficiency has been demonstrated to the satisfaction of his commanding officer.
b. Any soldier not qualifying in an MOS in ac- cordance with the above shall be classified as Basic (SSN 521) until such time as he qualifies for an appropriate MOS.
6. RECORDING MOS ON SOLDIER'S QUAL- IFICATION CARD, W.D., A.G.O. FORM NO. 20.
The MOS and SSN of the soldier will be recorded under the item "Classification in Military Special- ties," on the Soldier's Qualification Card, W.D., A.G.O. Form No. 20. The item, "Record of Current Service," in the column marked "Principal Duty" will always show the authorized duty title and SSN which represents the current duty assignment of the soldier. Entries in the "Principal Duty" column are subject to change as the soldier is given different duty assignments which fall within the area of skills represented by his MOS.
Example: In the case of the MOS of Clerk-Typist (SSN 405), the item "Classification in Military Specialties" will list Clerk-Typist — 405. If the sol- dier's principal duty assignment is Clerk-Typist the same entry will be recorded in the "Principal Duty" column, thus, Clerk-Typist— 405. In the event the soldier is subsequently assigned the duty of Chap- lain's Assistant, such additional entry will be re- corded in the "Principal Duty" column, thus, Chap- Iain's Assistant — 405. In this case, the item "Classi-

5. DETERMINATION OF SOLDIER'S MILITARY OCCUPATIONAL SPECIALTY (MOS).
a. An MOS will be assigned enlisted personnel only as follows:
(1) Through the successful completion of a course of training at a training center or service school, if it has been determined by proper authority that die course qualifies a graduate in a specialty. Whenever it is determined that a training course qualifies an individual for a military occupational specialty The Adjutant Genera] (Classification and Replacement Branch) will be furnished information as to the nature of the course and the MOS code designated.
(2) Through demonstrated ability to perform satisfactorily duties and responsibilities of an MOS in a unit or installation. Normally, a period of not less than 30 days shall be considered a minimum requirement.
(3) Through civilian experience, when of such nature as to be a practical counterpart of an MOS and when proficiency has been demonstrated to the satisfaction of his commanding officer.
b. Enlisted personnel not qualifying in an MOS in accordance with a above will be classified as follows:
( 1 ) Enlisted personnel not previously qualified in an MOS, or determined to be disqualified in a pre- viously acquired MOS, will be classified as Basic (SSN 521) until qualified in accordance with a above.
(2) Enlisted personnel not qualified for training in an MOS and others who fail to absorb specialist or tactical training will be classified as Duty Soldier II (SSN 188) or Duty Soldier III (SSN 590) de- pending on mental and physical capacity to per- form the non-specialized duties indicated in the job specifications contained in section IV.
6. RECORDING MOS AND PRINCIPAL DUTY ON SOLDIER'S QUALIFICATION CARD, WD AGO FORM 20.
a. The main title and SSN of the MOS acquired by a soldier in accordance with paragraph 5 will bo entered, chronologically as acquired, under the item "Classification in Military Specialties." Under this item only the main title of the MOS, as it ap- pears in section II of this manual, will be entered.
No other titles are authorized for this entry. (See par. 55, TM 12-425.)
b. Under the item, "Record of Current Service," in the column marked "Principal Duty" record the duty title and SSN which represents the current duty assignment of the soldier. For this entry, it is permissible to use, in abbreviated form, any of the alternate titles appearing at the head of the specification in this manual or other titles in com- mon usage (par. 10). Entries in the "Principal Duty" column are subject to change as the soldier is given different duty assignments which fall within the area of skills represented by his MOS. (See par. 57, TM 12-425.)
c. When an enlisted man performs a duty assign- ment not within tire area of skills represented by his previously acquired specialties the appropriate SSN and duty title will be entered in the "Principal Duty" column as indicated above but this SSN will not be entered under item "Classification in Mili- tary Specialties" until the enlisted man has demon- strated his qualifications in accordance with para- graph 5.
d. Example of the use of title and SSN for re- cording MOS and principal duty: In the case of the MOS of Clerk-Typist (SSN 405), the item "Classi- fication in Military Specialties" will list Clerk- Typist as 405. If the soldier's principal duty as- signment is Clerk-Typist the same entry will be re- corded in the "Principal Duty" column, thus, Clerk- Typist 405. In the event the soldier is subsequently assigned the duty of Chaplain's Assistant, entry will be made in the "Principal Duty" column, thus, Chaplain's Assistant 405. In this case, the item "Classification in Military Specialties" will remain posted as Clerk-Typist (SSN 405) since the duty assignment of Chaplain's Assistant falls within the area of skills represented by the MOS of Clerk- Typist.
e. Wherever a military occupational specialty title is followed by "designated type" or "designated equipment" or other similar phrase in parentheses, an appropriate descriptive phrase indicating the distinguishing characteristics of the job will be substituted therefor and shown in parentheses, for example, "302 Machine Operator (Engine Lathe) " or "302 Machine Operator (Drill Press)" and "659 Instructor (Mathematics) " or "659 Instructor (Jap- anese) ." In each instance where such a paren- thetical statement appears after the MOS title, the words "designated type" or similar phrase will not be recorded as part of the title.

fication in Military Specialties" will remain posted as Clerk-Typist (SSN 405) since the duty -assign- ment of Chaplain's Assistant falls within the area of skills represented by the MOS of Clerk-Typist.
7. QUALIFICATION IN AN MOS.
Accurate classification of each soldier in an appro- priate MOS is of utmost importance. No soldier should be classified in an MOS unless he is able to perform satisfactorily the duties and responsibili- ties required by the job in accordance with the standards set out below and qualification in an MOS will be accomplished as follows:
a. "Skilled" if the enlisted man has demonstrated that, given the tools and equipment of his occupa- tion he can perform all of his duties under sus- tained field, combat, or operating conditions with- out supervision beyond that inherent in the job itself.
b. "Semiskilled," if he can perform his duties under similar conditions but requires supervision.
c. "Potential" if he has sufficient familiarity with his tools and equipment and has such aptitudes and physical qualities as clearly warrants the assump- tion that' he will become qualified as semiskilled or skilled with additional training and experience. Such men should be able to perform the various elements of the job under close supervision.
8. SELECTION OF MAIN AND SECONDARY MOS.
a. Enlisted men may acquire sufficient knowledge' and skills to warrant classification in more than one military occupational specialty. In order to provide for the maximum utilization of a soldier's qualifications the following factors should be con- sidered in the selection of the main and secon- dary specialty, when it is desired to make a dif- ferentiation:
(1) Quality of performance.
(2) Length of experience or training.
(3) Recency df experience or training.
(4) Needs of the service, especially in scarce cate- gories of required skills.
b. An enlisted man may acquire a new MOS in accordance with paragraph 5a (1), (2) or (3). Until a new MOS is determined he shall be classi- fied under his present Military Occupational Spe- cialty, except in cases where he is not qualified to perform the duties and responsibilities thereof. In such cases he will be classified in accordance with paragraph 5b.
9. ORGANIZATION AND INTERPRETA- TION OF JOB SPECIFICATIONS.
a. Basis for job specification. The specifica- tions contained in this manual are based upon an
analysis of military duties performed by enlisted personnel, male and female. Material used in their preparation was obtained from tables of organiza- tion and current Army publications supplemented by field investigations o\ Army units in which the specialties were found.
b. Organization of a Job Specification. Each job specification contained in this manual is com- posed of several or all of the following elements:
(1) A descriptive title consistent with other titles and a specification serial number.
(2) Alternate titles. Where a military occupational specialty is known by another title established by common practice or usage, and where the type of training and experience available to an enlisted man qualifies him to perform more than one set of duties included under the MOS, titles alternate to the main titles are indicated, and the same SSN assigned.
(3 ) A statement of predominant duties and respon- sibilities including typical tasks falling within the occupational specialty. The general prin- ciple followed throughout is that jobs which require the same kind of training and experi- ence usually available" to enlisted men have been classified together under the one military occupational specialty.
(4) A statement of special qualifications indicat- ing knowledge and skills required for adequate performance of the specialty.
(5) Suggested substitutes indicative of related military occupational specialties from which personnel may be drawn in emergencies which will permit assignment with the least training and preparation.
(6) It will be noted that the job specifications ordi- narily make no mention of the education and experience, military or civilian, required. How- ever, it should be understood that all military occupational specialties are acquired through some form of Army service school training supplemented by on the job training or through on the job training only.
c. Interpretation of Job Specifications.
(1) The job specifications are intended as an aid and guide in assisting classification officers in the determination of an appropriate code des- ignation for a given set of duties and respon- sibilities, and uniformly to interpret and im- plement the regulations pertaining to person- nel classification and reporting. They do not restrict authority of commanding officers to change or prescribe additional duties and re- sponsibilities of subordinates. The objective has been to develop clear, usable, and man- ageable specifications rather than make each
3
MILITARY OCCUPATIONAL CLASSIFICATION OF ENLISTED PERSONNEL
one an indivisible unit. Differences in duties which do not affect seriously their treatment as a unit in classification and assignment work have been disregarded. The specifications are not detailed arid complete statements of the duties and responsibilities of a specific duty- assignment but describe typical tasks normally associated with the functional specialty.
(2) The classification of occupational specialties does not produce a system whereby every duty assignment can be found through a routine process of following an index. Sound judg- ment is required in applying the mechanical details of this classification structure. Consid- eration is not to be given to isolated phrases or sentences apart from their context.
(3) Authorized alternate titles as indicated in the job specification may be used on T/O's and manning tables to designate type of duty per- formed.
10. USE OF ALTERNATE OR COMMON JOB TITLES.
The proper construction and development of Ta- bles of Organization, common usage in the field, the type of training and experience available to the soldier in the field, and tradition of an arm or service may indicate a title other than the official or main title of an MOS. Provision for such varia- tion in title is arranged for as follows:
a. Wherever an MOS represents that type of spe- cialty which qualifies a specialist to perform one or more duties and responsibilities falling within the area of skills represented by the MOS, job titles alternate to the main title are shown to indicate the most probable duties to which a specialist may be assigned. Examples -of this are the use of such titles as Company Clerk, Battery Clerk, Headquar- ters Clerk, Chaplain's Assistant, or Typist with the MOS of Clerk-Typist (SSN 405), and, in an Anti- tank unit, Cannoneer, Gunner, Driver, Radio Tender, or Antitank NCO with the MOS of Anti- tank Gun Crewman (SSN 610) .
b. The general principle followed in consider- ing common titles which are used throughout the Army to indicate the supervisory nature of the duty assignment has been to determine whether or not a soldier on a supervisory level is responsible for the supervision of a composite group of specialists on the operational level.
(1) In those cases where a soldier on a supervisory level requires no more basic knowledge than tb-'.t of his military occupational specialty, plus his established leadership and other per- sonal qualifications, his supervisory status is
established by the enlisted grade to which he is promoted. His MOS remains the same.
Example: An Antitank Gun Crewman (SSN 610) who, because of evidenced leadership and other personal supervisory qualifications, is promoted to the position of Antitank Non- commissioned Officer. In this case, the MOS Antitank Gun Crewman (SSN 610) is not changed excepting that the alternate title of Antitank NCO (SSN 610) should be used and accordingly posted in the item, "Record of Current Service" in the "Principal Duty" col- umn of the Soldier's Qualification Card, W.D., A.G.O. Form No. 20. The enlisted grade to which the soldier is promoted in this case es- tablishes the supervisory nature of his as- signment.
(2) In those cases where a soldier on a supervisory level is responsible for supervising a com- posite group of specialties on the operational level and who, in order properly to supervise the group, must have a thorough knowledge of the varices kinds of military occupational specialists ov.sr which he has supervision, the enlisted grade to which he is promoted is not considered an adequate classification. By virtue of the knowledge the soldier develops of more than one MOS he automatically acquires a new MOS in this type of case. Example, the MOS of Administrative NCO (SSN 502) represents the kind of supervisory specialist who must be thoroughly familiar with more than one MOS on the operational level and such a specialist does not logically develop from only one MOS as in the case of the Antitank NCO. c. Other common titles which are used through- out the Army to indicate the supervisory nature of the duty assignment may also be used as alternate titles. Examples of this are Sergeant Major, First Sergeant, Platoon Sergeant, Chief of Section, Sec- tion Leader, and Squad Leader. However, the SSN used in each case will be that SSN which repre- sents the MOS of the Sergeant Major, First Ser- geant, Platoon Sergeant, etc.
Examples: A Platoon Sergeant of a Rifle Com- pany should be shown, as Platoon Sergeant, SSN 745, if he is assigned to a Rifle Platoon or 1812 if as- signed to an Infantry Platoon employing 60-mm mortars and light machine guns ; a Platoon Sergeant of an Antitank Company should be shown as Platoon Sergeant SSN 610; a First Sergeant whose duties require that he be an administrative special- ist should be shown, as First Sergeant, SSN 502; and a First Sergeant whose duties require a tactical specialist should be shown with the SSN covering his tactical specialty. For example, the First Ser-
4

geant of .an Infantry Rifle Company should be shown as First Sergeant, SSN 1812. The First Sergeant of a Tank Destroyer Company (Firing) should be shown as First Sergeant, SSN 610.
11. SPECIFICATION SERIAL NUMBER (SSN) DELETIONS AND CHANGES.
a. General. Appendix I contains a listing of specification serial numbers (SSN) appearing in AR 615-26 and its supplements which —
(1) Have been deleted from this manual or
(2) Have been retained in this manual because they are required in certain Tables of Organ- ization but are convertible to more appropri- ate SSN's in other Tables of Organization.
b. Appendix I, Table I. This table numer- ically lists all specification serial numbers (SSN) falling within the scope outlined in a(l) and (2) above, as follows:
(1) Where a deleted SSN is convertible to only one SSN, the SSN to which it is convertible is included in this table.
(2) Where an SSN has been deleted and is con- vertible to more than one SSN or has been retained but falls within the scope outlined in a (2) above, reference is made to and con- version is listed in appendix I, table II, except- ing where otherwise indicated.
c. Appendix I, Table II. This table contains a list of Tables of Organization by Arm and Service, by T/O number, showing the SSN's deleted or changed, together with the appropriate SSN's to be used in the respective T/O's.
Example: Platoon Sergeant (SSN 651) has been deleted by SSN only._ Where this SSN (651) ap- pears in appendix I, table I, there is included a reference as follows: "See Appendix I, Table II." Before reference is made to table II first determine the particular T/0 involved, then turn to the ap- propriate arm or service in table II and locate the appropriate T/O number listed therein. The proper SSN to be used will be listed by T/O line and column number. If the pertinent T/O is not listed in table II, no correction is necessary as the T/O is correct. Table II does not include classified T/O's. Corrections involving classified T/O's will be processed by other methods as will be prescribed from time to time.
12. USE OF ALPHABETICAL INDEX.
a. The index (section V) contains a complete cross-index of the military occupational specialties included in this manual. It contains — (1) Principal Titles. These are descriptive titles listed in capital letters and are the exact designations found in sections III and IV.
They are the only titles which will be used in completing the item "Classification in Mili- tary Specialties" on the Soldier's Qualifica- tion Card, W.D., A.G.O. Form No. 20, and other allied reports and forms, such as requi- sitions, service records, and orders.
(2) Alternate Titles. These are descriptive titles listed in lower case letters with initial capitals. These titles are authorized duty titles which represent duty assignments which fall within the area of skills represented by the military occupational specialties (principal titles) to which they refer. Their formal use is author- ized only in Tables of Organization and in completion of the item "Record of Current Service" on the Soldier's Qualification Card, W.D., A.G.O. Form No. 20.
(3) Cross-index Titles. The cross-index titles, also listed in lower case letters with initial capitals, are rearrangements of principal and alternate titles and provide for easy location of military occupational specialties when the exact principal or alternate titles are not known.
b. A title cannot be completely descriptive of a specialty. It is important, therefore, that refer- ence be made to the content of the specification be- fore a specification serial number and title are se- lected.
13. DEVELOPMENT OF FUNCTIONAL FIELDS.
Section II gives a grouping of military special- ists within ten broad functional fields. The pur- pose of this section is to indicate the. functional fields and the appropriate specialists therein in order to assure using, requisitioning, or assigning occupational specialists for purposes in agreement with the skills and knowledges of a particular MOS.
14. USE OF THIS TECHNICAL MANUAL.
a. General. The use of this Technical Manual by the Army will be, in general, to accomplish the purpose stated in paragraph 1. Specific applica- tions will vary in accordance with the missions of the using units or organizations, and such War De- partment publications as may direct changes or modifications.
b. Reception Centers. The civilian occupa- tions of enlisted men will be classified in accordance with TM 12-^26. The recommended military assign- ment made on the W.D., A.G.O. Form No. 20 Card by reception centers will be based on —
(1) A sound evaluation of such factors as physical capacity, leadership, experience, education,
5
MILITARY OCCUPATIONAL CLASSIFICATION OF ENLISTED PERSONNEL
skills (hobby or occupational), test scores, and aptitudes which indicate probable suc- cessful performance of a military occupational specialty.
(2) The needs of the Army for certain military occupational specialists as shown by such War Department publications as Requirement and Replacement Rates, lists of critical shortages, and other similar publications.
(3) The types and kinds of training programs available to enlisted men within replacement training centers, service schools or units.
(4) Reception centers will not recommend a mili- tary occupational specialty on a supervisory level. If a soldier possesses the potentialities of a military occupational specialty on the supervisory level he should be recommended for a military occupational specialty on the operational level. In filling blanket requisi- tions for units, the rate for military occupa- tional specialties on the supervisory level (when shown) should be added to that of the military occupational specialties on the ap- propriate operational level.
c. Training Centers and Service Schools. The use of this Technical Manual by Training Cen- ters and Service Schools will include:
(1) Re-evaluation of the qualifications of enlisted men for the purpose of assigning each soldier to that type of training which he can most readily absorb and thereby be of the greatest value to the service. Consideration should be given to the physical capacity, leadership qualities, and intelligence incident to the MOS for which the particular course is intended to train and the SSN under which the enlisted man will be reported as available for assign- ment. (See par. 5a(l) .)
(2) Enlisted men upon successful completion of a course will be properly classified with an, MOS in accordance with paragraph 5a (1) and such War Department publications as Cir- cular No. 233, War Department, 1943, "En- listed Men — Requisitions for Replacements Trained by Army Ground Forces," as amended by section III, Circular No. 331, War Depart- ment, 1943, and Circular No. 189, War De- partment, 1944, "Requisitions for Replace- ments of Enlisted Men Trained by Army Service Forces," or similar publications. This entry shall be made on the Form No. 20 Card under the item "Classification in Military Spe- cialties" by showing the official title of the MOS under the heading "Designation" and the SSN under the heading "Specification Serial Num- ber." The degree of proficiency under "poten-
tial," "semiskilled" or "skilled" will be shown by the initials "RTC" for replacement train- ing center and "SS" for service school in the appropriate space.
d. Field Units. Divisions and separate units will make use of this manual properly to assign replacements to duties commensurate with their qualifications as indicated either by the recom- mended military assignment by reception centers or the designated MOS of men received from re- placement training centers, service schools or other units. Men received from reception centers will ac- quire an MOS in a unit in accordance with para- graph 5a(2) or (3). Enlisted men given a quali- fied MOS from a replacement training center or service school as indicated by the initials RTC or SS under the item "Classification in Military Spe- cialties" will be given an MOS as soon as they dem- onstrate satisfactory performance of the duties and responsibilities of such MOS. Such notation will be made in the item "Classification in Military Specialties" of the card by crossing out the initials RTC or SS and adding the new date. These nota- tions will be initialled by the responsible officer. Classification officers and unit personnel officers in divisions and separate units will assign military occupational specialties to enlisted men only in accordance with paragraphs 2 and 5.
e. Replacement Depots and Personnel Re- placement and Reassignment Centers. Replace- ment depots and personnel replacement and reas- signment centers will make full use of this man- ual—
(1) To determine that the enlisted man has been properly classified in an MOS in accordance with paragraphs 2 and 5.
(2) To assign such men out as replacements only on requisitions for such specialists.
(3) Where exigencies of the situation make it im- practicable to assign men in accordance with their specialties, every attempt will be made to assign specialists to closely allied assign- ments which can be determined by a study of sections II and IV of this manual. Most de- scriptions list appropriate substitute military occupational specialties, and substitute assign- ments should be based on these suggestions wherever possible.
f . Tables of Organization and Tables of Organization and Equipment. Tables of Organ- ization and other personnel manning tables should indicate the kinds of military occupational special- ists needed by the T/O unit to perform its mission. Appropriate use of alternate titles will indicate the probable use or duty assignment of such specialists within T/O's. Section II has been constructed to

INTRODUCTION
clarify the types and kinds of military occupational specialists in accordance with the mission they will be required to perform.
15. SUGGESTED CHANGES, CORREC- TIONS, REVISIONS, AND DELETIONS OF MILITARY OCCUPATIONAL SPE- CIALTIES.
a. In order to maintain this manual, additions, changes, corrections, revisions, and deletions will be required from time to time. The cooperation of classification, requirement, and training officers is essential in keeping subject matter in this manual current with new developments. In order to insure careful consideration of changes, the following procedure will be followed:
(1) Before formally requesting the inclusion of a new military occupational specialty in this manual, the principle outlined in paragraphs 2a and b will be carefully studied.
(2) After such study, a review of the military oc- cupational specialties in this manual will, in many instances, indicate one or more special- ties which adequately represent the kind of specialist required. Where this is the case a new MOS should not be requested. Rather, the MOS most closely representing the kind of specialist required should be selected and a review made of the main and alternate titles, if any, of the MOS. If an appropriate title is indicated no further action on request is nec- essary and the MOS should be used by selected title and the SSN governing the MOS.
(3) However, where the MOS adequately repre- sents the kind of specialist required, but no appropriate title is indicated, a request to The Adjutant General, Classification and Replace- ment Branch, Washington 25, D. C., through channels, should be made stating the sug- gested alternate title required and the MOS and SSN to fwhich it is considered alternate.
(4) From time to time military occupational spe- cialties become obsolete for various reasons and, therefore, should be deleted from the man- ual. Once it has been determined that an MOS is no longer necessary notification through the channels outlined in part 3 of this paragraph should be accomplished.
(5) In those cases where the procedure outlined in (1) and (2) above does not provide a solu- tion to the situation a request for change should be prepared in the following manner:
To: The Adjutant General, Classification and
Replacement Branch, Washington 25, D. C. (Through Channels)
Subject: Suggested Changes in Military Occupa- tional Specialties (TM 12-427).
Enlisted Mans Military Occupational Specialty
1. Title.
2. Arm or service. '
3. Indicate T/O number and title or manning table,
and state briefly mission of unit.
4. Type of supervision governing specialty:
a. Commissioned Officer (Title and Code Num-
ber in accordance with TM 12^106 or 407) .
b. Noncommissioned Officer (Title and SSN in
accordance with this manual).
5. Supervisory responsibilities of specialty:
a. Over other noncommissioned officers (give
Title and SSN).
b. Over nongraded enlisted men (give Title and
SSN).
6. Job Analysis of Military Occupational Specialty
showing —
a. Duties performed (state in detail, explaining specifically what, how, when, and why, and the tactics, weapons, tools, equipment, and materiel involved) . '
6. Job knowledge and skill required (state in de- tail the techniques, abilities, dexterity, ac- curacy, (speed, tolerances) special training, and other characteristics required).
c. Training. required. Indicate whether obtained
by RTC or school training, unit training or both. Indicate whether this specialist is trained specifically as an individual military specialty.

MILITARY OCCUPATIONAL CLASSIFICATION OF ENLISTED PERSONNEL
7. Physical Requirements (indicate physical charac- teristics necessary to successful performance of this MOS. State in detail unusual physical requirements or to what extent less physically qualified personnel could perform duties in- volved ) .
16. CODING OF PARACHUTISTS, HORSE- MEN, AND INSTRUCTORS.
a. Parachutists and Horsemen. The terms "Parachutist" and "Horseman" do not represent military occupational specialties. Rather, they rep- resent additional qualifications required of para- troopers and horsemen whose military occupational specialties vary in accordance with the kinds of MOS's required to man Tables of Organization call- ing for the additional qualifications of parachut- ing and horsemanship. However, in order ade- quately to control the requisitioning of and other- wise to indicate the parachute or horseman qualifi- cations the digit 7 will prefix the basic specifica- tion serial number of Paratroopers in all cases and the digit 9 will prefix the basic specification serial number of Horsemen.
Examples: To identify a Rifleman (SSN 745) who is additionally qualified as a Paratrooper the basic SSN will be prefixed thus, 7745. To identify a Rifleman (SSN 745) who is additionally qualified as a Horseman the basic SSN will be prefixed thus, 9745.
b. Instructors. It is not feasible to develop job specifications for the many instructional duties performed by enlisted personnel. A careful analy- sis of instructor specialties has shown that the field of instruction, both in kind and scope, usually parallels the functional performance of a military occupational specialty and, hence, can be repre- sented by the same SSN.
Example: The skills and knowledge represented by a Rifleman (SSN 745) and ah instructor in the same field are sufficiently alike, except for person- ality and other factors not classifiable herein, to permit classification by the same SSN. For re- cording purposes the word "Instructor" will be
entered in parenthesis in the items "Classification in Military Specialties" and "Present Duty" to- gether with the military occupational specialty title. However, in the rare cases where personnel are per- manently assigned to instructional duty, and are not qualified in a military occupational specialty related to the course of instruction, the use of Technical Instructor (SSN 659) is authorized if the instructor is highly skilled or Basic (SSN 521) if the instructor has no military occupational spe- cialty.

Section II
Functional Grouping of Military Occupational Specialties
To facilitate the allocation and location of ap- propriate MOS's in this manual, the military occu- pational specialties have been grouped under ten broad functional fields which, in turn, have been subdivided into subgroups of related occupations. No single criterion has been followed in assigning a job to a particular grouping. Generally, the func- tional relationship among the specialties has been the determining factor in their grouping. In some cases, consideration has been given to other factors, such as the qualification requirements, T/O needs, and the mission to be performed, necessitating a de- parture, in such instances, from the functional ar- rangement. Where this has been necessary, how- ever, such grouping should prove of greater benefit to the user. The ten groupings are as follows:
1. Gunnery and Gunnery Control.
