NCOTMB Soldier of the Month Board (SOTMB) Practice Exam

In equipment maintenance, TM stands for Technical Manual. This is the official, detailed guide technicians use for performing repairs, maintenance, and troubleshooting, and it includes procedures, diagrams, torque specs, lubrication points, and safety notes. You’ll often see a TM number assigned to a specific piece of equipment, like TM 9-xxx, which ensures everyone follows the exact, approved steps. The other terms describe different kinds of documents—Technical Memorandum is a technical note or memo, not the primary maintenance guide; Training Manual is meant for teaching how to operate or maintain but is not the hands-on reference for a specific piece of equipment; Technical Series isn’t the standard designation used for equipment maintenance references.
