Which of the following is a function of maintenance?

• A. Maintenance is a commander's responsibility
• B. Inspection
• C. Planning
• D. TMDE

Answer: (C)

Planning guides maintenance actions by defining what work is needed, when it must be done, and what resources are required. A solid maintenance plan schedules preventive tasks, coordinates with supply for parts, and prioritizes work to minimize downtime and keep equipment ready. Inspections and the use of TMDE are important activities within maintenance, but they are carried out under the plan rather than representing the planning function itself. Accountability to the commander describes who is responsible for maintenance, not what maintenance does as a function. So planning is the function that organizes and directs all maintenance actions in this context.
