Final answer:
The War Plans Additive Report (WPARR) provides a baseline for additional resources needed to execute potential war plans, detailing forces, resources, and budgetary requirements for various conflict scenarios.
Step-by-step explanation:
The War Plans Additive Report (WPARR) is a document related to defense strategy and resource allocation used by the United States military. It does not authorize actions in a standalone sense; rather, it provides a descriptive baseline for what operational plans may require in terms of additional resources or changes, beyond the base structure of the military's needs.
The WPARR details the specific forces, resources, and budgetary requirements needed to execute potential war plans that have been conceived in the case of various global conflict scenarios.
