Hey there, I'm a high school junior and planning my path after graduation. I was wondering, for perspective, which branch of the U.S. military is the biggest in terms of personnel?
In terms of active-duty personnel, the United States Army is the largest branch of the U.S. military. As of 2021, it had over 480,000 active-duty personnel. However, if you consider both active-duty and reserve personnel, the Army and Air Force are quite close in size. This changes from year to year, of course, so for the most accurate and current information, you would need to refer to the Department of Defense's annual Demographics Report or similar official sources. Choosing a path in the military should be based on your interests and goals rather than the size of the branch, though. Each branch has unique missions, career opportunities, and cultures.
