Direct Service to POTUS: Which Military Branch?

Hey there folks, was watching some political drama and it got me thinking. Which branch of the military directly serves the President of the United States (POTUS)? I assume there's a specific one, right?

While it's an interesting question, you'll find that no single branch of the U.S. military exclusively serves the President of the United States (POTUS). In reality, all branches of the military fall under the Department of Defense, which is under the command of the POTUS who hold the title of Commander-in-Chief.

Although all branches are accountable to the president, some elements might seem more directly involved due to their functions. For instance, the Marine Corps is often associated with the POTUS as the Marines operate the Marine One, the call sign of any Marine Corps aircraft carrying the president. The U.S. Army is also associated by virtue of The Old Guard, which among other duties, provides the official ceremonial unit and escort to the POTUS.

Not to be left out, the U.S. Air Force operates Air Force One, the aircraft that carries the president. At secure at high-altitude, it's meant to serve as a mobile command center in case of an attack on the United States.

Remember that this doesn't mean these branches are more important or have higher status, rather it's a part of the wide range of each branch's responsibilities. Each branch - Army, Navy, Air Force, Marine Corps, Coast Guard, and Space Force - has unique responsibilities, all of which collectively serve the best interests of the nation and its leaders.
