When you join a branch of the U.S. military,  you either enlist or commission as an officer.  

Enlistment requires no education beyond a high school diploma and can be accomplished right out of high school, while commissioned officers are required to have a college degree.  

You can pursue commissioning as an officer through the Reserve Officers' Training Corps (ROTC) at a designated college or at a military academy.  Click on the buttons above to learn more.
