The military has produced thousands of manuals to document the operation and maintenance of vehicles. This page will help you understand how U.S. military manuals are numbered and organized.
U.S. Army Technical Manuals (TMs) are “Manuals that contain instructions for the installation, operation, maintenance, and support of weapon systems, weapon system components, and support equipment. They normally include operational and maintenance instructions, parts lists, and related technical information or procedures.”
TM’s refer to specific equipment (e.g. M1078A1 FMTV) and are numbered according to a definite format. The number of the manual contains information that specifies what equipment it describes and what sort of manual it is.
The Army numbering format (e.g. TM 9-2320-365-10) is the one used to identify the manual and consists of these parts:
- Type of manual. Examples:
- TM Technical Manual
- LO Lubrication Order
- TB Technical Bulletin
- Branch number. Examples:
- 9 Ordnance
- 10 Quartermaster
- 11 Signal
- Federal Supply Class (FSC). Examples:
- 1005 Guns, through 30mm
- 2320 Trucks and Truck Tractors, Wheeled
- 2610 Tires and Tubes, Pneumatic, Except Aircraft
- Serial number assigned to the documentation series.
- Maintenance level. Examples:
- 10 Operator/crew maintenance
- 20 Unit maintenance
- 24 Unit through intermediate general support maintenance
- 30 Intermediate direct support maintenance
- 34 Intermediate direct support and intermediate general support maintenance
- 40 Intermediate general support maintenance
- Suffix lettering. Examples:
- P repair parts and special tools list (RPSTL)
- &P maintenance manual that includes a repair parts and special tools list
