Army Technical Bulletin Manuals (TB)

U.S. Army Technical Bulletins

Explore U.S. Army Technical Bulletins issued to communicate focused technical information and instructions for military equipment and support systems. Identified by the abbreviation TB, these publications may address inspection, maintenance, testing, modification, preservation, storage, calibration, safety, supply, and specialized operating procedures. Technical Bulletins often supplement broader Technical Manuals by covering a specific issue, process, or equipment update. These publications support historical research, equipment identification, museum interpretation, and restoration reference. They are documentary materials rather than functional weapons or explosive ordnance.
