Figure 4. A DA Form 4569 Requesting Publications from the Adjutant General's Publication Center,
There are two publications numbering systems, one for administrative publications and one for training,
organizational, and equipment publications. Administrative publications have series numbers based on a
classification of subject matter. Figure 5 shows a partial list of that classification. After the series number is a
number used to distinguish between other regulations on the same subject. For example, AR 310-2 is
Identification and Distribution of DA Publications and Issue of Agency and Command Administrative
Publications. AR 310-3 is Preparation, Coordination, and Approval of Department of the Army Publications.
Training, organizational, and equipment publications (including technical and supply publications) also have
series numbers (Figure 6). The series number is followed by a dash and four numbers that are the Federal Supply
Class (FSC) assigned to the equipment covered by the manual. This number is followed by a dash and up to four
numbers between 001 and 9999. This group of numbers distinguishes the several manuals covered by the same
FSC. Finally, there is a dash and two numbers for the level of maintenance to which the manual applies. For
example, in TM 9-2345-6789-20, -20 stands for unit level. If the manual lists parts, there will be a letter P added
(for example, TM 9-2345-6789-20&P). Taken together, these numbers indicate the missile or kind of
ammunition the publication is about and the level of maintenance.
