Office symbols


General guidelines


B. TRADOC service schools and activities


1. Purpose. The DCSC4 is responsible for assigning office symbols to staff elements of HQ TRADOC and to TRADOC service schools, activities, and assigned miscellaneous units.

2. Reference. TRADOC Reg 10-5 (Headquarters, United States Army Training and Doctrine Command) is a required publication.

3. Office symbols. HQ TRADOC office symbols are established as follows, consistent with the organizational structure shown in TRADOC Reg 10-5:

    a. Office symbols are limited to not more than seven letters. Hyphens will be placed between the fourth and fifth letters.

    b. The first two letters have been assigned to U.S. Army Training and Doctrine Command by HQDA and are "AT."

    c. The third and fourth letters represent the Command Group and general and special staff offices.

    d. After the hyphen, the fifth letter will represent a directorate, a comparable element, or next organizational element below general and special staff level.

    e. The sixth letter will represent a division, a comparable element, or next lower organizational level.

    f. The seventh letter will represent a branch, comparable element, or the next lower organizational element.

    g. The letter "Z" may be used as the fifth letter for the immediate office of the head of a general or special staff office. The letter "Z" may be used in conjunction with the letters "A" thru "W" to represent officials in the office.

    h. The letter "X" may be used as the sixth letter for the executive officer of general or special staff offices.

4. General guidelines.

     a. Office symbols for HQ TRADOC are listed in appendix A. Office symbols will not be changed solely because an activity's name has changed.

     b. Commanders of organizations and units listed in appendix B may further assign office symbols to elements of their respective offices or commands.

     c. Office symbols for principal installations, field operating activities, service schools, activities, and miscellaneous units are limited to not more than nine letters. Hyphens will be placed between the fourth and fifth letters and the seventh and eighth letters. The first four letters have been assigned. These symbols should be constructed at the local level in a manner similar to the HQ TRADOC construction method.

     d. Chiefs of general and special staff offices, HQ TRADOC, will send requests for changes to DCSC4, ATTN: ATIM-I. Coordinate all changes in organizational structure with Commander, TRADOC, ATTN: ATIM-I, 102 McNair Dr, Fort Monroe, VA 23651-1047, prior to implementation for assignment or deletion of office symbols. Notify the Mail and Distribution Center (ATZG-BO-PM) of approved office symbol changes so that mail can be properly routed and distributed.
