As of September 2023, the US military consisted of 2.86 million people worldwide. The CIA reports that the US has the world’s third-largest active military by size, surpassed only by China and India in 2023.
These forces are spread across six main service branches: the Army, Navy, Air Force, Marine Corps, Coast Guard, and, as of 2019, the Space Force – all tasked to protect and service the US.
