(This pamphlet together with FM 21-7, January 1, 1943, supersedes FM 21-6, July 1, 1942; including paragraphs 1-3, Training Circular No. 70; paragraphs 1 and 2, section II, Training Circular No. 78; sections I and III, Training Circular No. 90; section I and paragraphs 1-3, section II, Training Circular No. 98, War Department, 1942; and paragraphs 1 and 2, Training Circular No. 1, War Department, 1943.)

• 1. SCOPE.—This manual contains lists or references to lists of publications or matter required for military training.*

• 2. TEXTS.—The primary texts for training in schools, including extension courses, in garrisons, in training centers, and in the field are War Department training publications issued, as a general rule, in the form of Field Service Regulations, Field Manuals, and Technical Manuals. Technical Regulations will eventually be eliminated by the inclusion of suitable material in other training documents.

a. Field Service Regulations, which are published as Field Manuals, constitute the basis of instruction of all arms and services in the operations of war and announce the basic doctrines which are expanded and applied in other texts. They contain the fundamental considerations concerning the employment of the combined arms and the combined services, and the strategical, tactical, and administrative employment of larger units and territorial commands.

b. Field Manuals constitute the primary means for expanding the basic doctrines of the Field Service Regulations. They are published in three general divisions as follows:

(1) The Field Manuals for the several arms and services contain instructions relative to the tactics and technique involved in the employment of such arm; and services, together with data needed in the theater of operations.

(2) The Basic Field Manuals contain training and reference data applicable to more than one arm or service, with special reference to the smaller units.

(3) The Staff Officers' Field Manual is a compilation of information and data to be used as a guide for the operations in the field of the general staff or a similar staff group of all units in peace and war.

c. Technical Manuals consist of a series of pamphlets supplementing the Field Manuals, covering subjects the separate treatment of which, is considered essential to a fuller accomplishment of the training prescribed in the Field Manual series. The scope of this series includes pamphlets describing matériel and containing instructions for the operation, care, and handling thereof; guidebooks for instructors and specialists; material for extension courses; reference books; and the like.

• 3. NUMBERING.—The number of each pamphlet will consist of two parts: the basic number and subnumber.

a. The basic numbers will be as follows:

b. The subnumbers for Field Manuals will be from 1 to 199 and for Technical Manuals 200, etc.

c. Examples:

d. Reference.—For references in correspondence or publications, Field Manuals and Technical Manuals will ordinarily be referred to by number only, that is, FM 6-110 or TM 4-235; if it is necessary to identify the publication further, the title will be added, that is, FM 6-110, FAFM, Pack Artillery; TM 4-235, Coast Artillery Target Practice.

• 4. CHANGES.—a. In order that prompt recommendations may be submitted, each agency charged with the preparation of a manual will keep a folder of suggested changes. Serious errors will be reported at once.

b. How effected.—When the subject matter contained in a pamphlet is changed or corrected, it will be published as a change only when it is deemed inadvisable to revise and reprint the entire pamphlet.

c. When promulgated.—Changes will, as a general rule, be published as soon as practicable after the necessity for a change arises. The number and date of the change will follow the classification number at the end of each paragraph. A change requiring immediate attention will be published in a War Department numbered Training Circular (see sec. II), or as a printed change.

d. How published.—When printed, changes will be published on one side of the page only so that they may be cut and pasted over the matter which they change.

e. How numbered.—Changes will be numbered in a single series for each edition of each pamphlet, a new series being started with the first change pertaining to an edition.

f. Drafts.—Drafts of matter submitted for publication as changes will contain both the existing and the proposed matter, the matter to be omitted, with a line drawn through it and the proposed matter underscored.

g. Minor changes.—Minor changes, such as those intended merely to change the rhetorical construction of a portion of regulations for purposes of clarity or those not involving a change of doctrine, will be allowed to accumulate and will be published in a revision of the regulations in question.

h. Changes affecting other publications.—When changes are prepared which may affect other War Department publications or portions thereof to the extent of requiring modifications of the latter, changes to the other publications so affected will be prepared and submitted at the same time.
