Which element is included in the U.S. Navy according to the material?

• A. Naval battle groups, air force squadrons.
• B. Cavalry regiments and field artillery brigades.
• C. Naval combat and service forces, naval aviation, and the Marine Corps.
• D. Coast Guard units exclusively.

Answer: (C)

The material identifies three components as part of the U.S. Navy: naval combat and service forces, naval aviation, and the Marine Corps. Naval combat and service forces cover the fighting units at sea and the support elements that keep operations going. Naval aviation encompasses all Navy aircraft and their air operations. The Marine Corps, while a separate branch, functions as a component under the Department of the Navy, providing expeditionary capabilities and land power when needed. This combination shows how the Navy integrates sea power, air power, and Marine land operations.

The other options mix in elements from other services or misrepresent organizational boundaries. Air force squadrons belong to the Air Force, not the Navy. Cavalry regiments and field artillery brigades are Army units. Coast Guard units are a separate service, not counted as Navy elements in this context.
