What best defines War Reserve Material (WRM)?

• A. Mission essential principal end items, secondary items, and munitions required to attain operational objectives in the scenarios authorized for sustainability planning and other stock age objectives. Obtained during peacetime.
• B. Items stored overseas only and used exclusively during wartime.
• C. Any spare part kept at the unit level for routine maintenance.
• D. Items procured after the start of operations in theater.

Answer: (A)

War Reserve Material is pre-planned, pre-positioned stock that ensures you can sustain operations in authorized scenarios without depending solely on immediate resupply. It includes mission essential end items, their secondary items, and munitions needed to reach operational objectives, all identified for sustainability planning and stock age objectives. The key point is that this material is obtained during peacetime to ensure readiness before operations begin, so it’s available when needed and not dependent on wartime procurement.

That’s why this option fits best: it captures the idea of planned, pre-positioned, essential items and munitions kept ready to sustain operations under defined scenarios. It’s not limited to overseas or to wartime only, it isn’t just spare parts kept at unit level for routine maintenance, and it isn’t something procured after operations have already started in theater.
