Step-by-step explanation:
The manual that multiple services use and follows a layout developed by the branch of service that initially had it developed is called a Standard Technical Manual.
This manual serves as a comprehensive guide, providing technical information and instructions for the operation, maintenance, and repair of various systems and equipment used in the military.
For example, the Army may develop a Standard Technical Manual for a certain piece of equipment, and then the other branches of service, such as the Navy or Air Force, would also use the same manual and follow its layout.
