Who is responsible for determining the size and organization of the Army?

• A. President of the United States
• B. Congress
• C. Department of Defense
• D. Military Commanders

Answer: (B)

The responsibility for determining the size and organization of the Army lies with Congress due to its constitutional powers. The U.S. Constitution grants Congress the authority to raise and support armies, which includes making decisions on manpower levels, force structure, and budget allocations. This legislative power ensures that civilian oversight is maintained over the military, integral to the principle of civilian control of the armed forces.

Congress exercises this authority through the National Defense Authorization Act (NDAA) and related legislation, which sets the framework for military funding and strategic priorities. While the President and the Department of Defense may provide recommendations and strategic guidance based on national security needs, it is ultimately Congress that enacts the laws defining the Army's size and structure. Military Commanders focus on operational and tactical decisions within the context of the established organizational framework but do not have the authority to alter the size and organization of the Army as that remains a legislative function.
