Presidents that Served in the Military

Here is a list of the 31 presidents who served in the U.S. military. It would be easy to assume that an American President must have some background in military service–the President is the Commander-In-Chief, after all. But the reality is that military service is NOT a prerequisite to hold the highest office in America. That said, a significant number of U.S. Presidents did serve in some capacity.

How many American Presidents served in the United States military? The U.S. Constitution specifies civilian control of the armed forces, and no sitting general may also hold the office of President. But a former military member can, and many did. The actual number of sitting presidents who have served may surprise you – of the 46 Presidents, a whopping 31 also had military service.

That means that 15 did not serve. Which presidents did NOT serve? Most notably, Presidents Joe Biden, Donald J. Trump, Barack Obama, Bill Clinton, and Franklin D. Roosevelt.

Roosevelt’s entry is notable as he served as Assistant Secretary of the Navy during World War One. He tried to resign in order to enter uniformed service but his resignation was not accepted and he did not join.

The last president to serve in the military was George W. Bush who served in the Texas Air National Guard. The last president to see combat was George H. W. Bush.

Thirty-One Presidents With Military Backgrounds

Many of the U.S. presidents who served prior to World War Two served in the Army, but since WW2 many have served in the Navy. President George W. Bush served stateside duty in the Texas Air National Guard during Vietnam, Ronald Reagan served in both the Army Reserve and U.S. Army Air Forces.

At the time of this writing, no member of the U.S. Marine Corps or the United States Coast Guard has ever held the office of President. At least five Presidents served in state militias including Chester Arthur, Abraham Lincoln, and James Buchanan (in no particular order).

Among the youngest of those who served at time of entry, President William Henry Harrison started a military career at 18 years of age. A dozen of the Presidents who served were Generals including George Washington, Andrew Jackson, Ulysses S. Grant, Rutherford B. Hayes, and Dwight D. Eisenhower.

Eight presidents served during World War II, while seven served in the military during the American Civil War.

The Most Recent President To Experience Combat

The last U.S. President to see combat at the time of this writing was President George H.W. Bush, who earned the Distinguished Service Flying Cross as a member of the Navy Reserve. President Ronald Reagan served during World War Two, but his service was stateside-based.

President Jimmy Carter served aboard submarines and battleships as a Navy Lieutenant and Richard Nixon earned two Service Stars for his work as a Reserve Commander in the U.S. Navy.

President Lyndon Johnson was awarded the Silver Star for his work as an aerial combat observer when his aircraft was attacked over New Guinea. President John F. Kennedy not only served as a Lieutenant during World War Two, but was also awarded the Purple Heart for his efforts.

In terms of military service, it doesn’t get any more “up there” than the record of General Dwight D. Eisenhower, who before he became President served as a General during World War One, and as the Supreme Allied Commander in Europe during World War II.

The three presidents to hold the highest military ranks were: George Washington, Dwight D. Eisenhower and Ulysses S. Grant, respectively.

James Buchanan, the 15th president, held the lowest rank among Veteran U.S. presidents. He was a private (E-1) in the Army, and the only president who enlisted without becoming a commissioned officer.
