What does the War Plans Additive Requirements Report (WPARR) specifically authorize?

The War Plans Additive Requirements Report (WPARR) is specifically designed to identify and authorize additional resources needed to fulfill war plans. Among the choices provided, the correct answer is vehicles. This report outlines extra requirements that go beyond the baseline capabilities, ensuring that forces are adequately equipped to operate effectively in a wartime scenario.

While personnel assignments, shelter resources, and equipment supplies are all crucial components of military logistics, they are not the primary focus of the WPARR. This report specifically highlights the need for vehicles due to their critical role in mobility, logistical support, and operational effectiveness during military operations. Proper vehicle authorization ensures that units have the necessary transport capabilities to deploy personnel and equipment to where they are needed most in a conflict.
