Which level of command utilizes part one of the War Plans Additive Requirements Report (WPARR)?

The correct choice indicates that Major Commands (MAJCOM) utilize part one of the War Plans Additive Requirements Report (WPARR). MAJCOMs play a crucial role in the planning and execution of military operations and are responsible for overseeing the logistics and resource requirements that support those operations. Part one of the WPARR specifically focuses on articulating the additional resources and support required to execute wartime plans effectively, which is critical for MAJCOMs as they assess and allocate resources across their subordinate units.

This level of command is integral in translating high-level strategic objectives into actionable logistics plans, enabling effective preparation for potential conflicts. By utilizing the WPARR, MAJCOMs ensure that they can anticipate and manage the additive requirements necessary to maintain operational readiness, which reinforces their mission effectiveness at a broader operational level.
