List of Presidents of the United States by military service
The United States Constitution names the President of the United States the commander in chief of the US armed forces. However, previous service in the military is not a pre-requisite for the position of president. As of the 2008 presidential election, no member of the US Marine Corps or US Coast Guard has yet been elected President. The most frequent military experience is Army/Army Reserve with 15 presidents, followed by State Militias at 9, Navy/Naval Reserve at 6 and the Continental Army with 2 presidents serving. The following list outlines the military service of each president before becoming the commander in chief.
