What is the collective term for the military forces of the United States?

The term "The Armed Forces" collectively refers to all branches of the military in the United States, which includes the Army, Navy, Air Force, Marine Corps, and Coast Guard. This designation encompasses the full spectrum of military personnel and capabilities that are organized under the Department of Defense and other related departments.

The other terms listed refer to specific components of the military. The National Guard, for instance, includes units that serve both state and federal missions but is only part of the overall structure. The Coast Guard operates predominantly within maritime law enforcement and safety roles, functioning differently from the other branches. Lastly, the Reserve Forces are part-time military personnel who can be activated during emergencies but do not represent the total military force. Each of these options plays an important role in national defense but does not encompass all military branches collectively as "The Armed Forces" does.
