Army strong

The U.S. Army is comprised of the Regular Army, Army National Guard, and Army Reserve, and makes up the land warfare branch of the U.S. military. While General is the highest rank one can achieve within the Army, the U.S. president is the Commander-in-Chief and head of the military overall.
