Military Branches in the Pentagon?

Hi there. Recently, I've been considering the military as a potential path after graduation. I was curious, which branches of the military have a presence in the Pentagon?

All five of the major branches of the U.S. military maintain a presence at the Pentagon. These include the U.S. Army, the U.S. Navy, the U.S. Air Force, the U.S. Marine Corps, and the U.S. Coast Guard. The Pentagon serves as the headquarters for the Department of Defense, whose responsibility is to coordinate and supervise all agencies and functions directly related to national security and the U.S. Armed Forces.

The U.S. Space Force, which was established in 2019 as the newest branch of the military, also has a presence in the Pentagon. Its responsibility lies in ensuring the U.S.'s security in space—monitoring ballistic missile launches, tracking space debris, and maintaining satellites that allow the other branches of the military to communicate are all within its purview.

The offices of the Department of Defense Leadership (including the Secretary of Defense and Joint Chiefs of Staff) are also located in the Pentagon. Thus, if you have aspirations of working in military leadership or administration, the Pentagon could indeed be a destination in your career.
