The U.S. Presidents Who Served in Our Military

The first veterans of the United States served under Commander George Washington of the Continental Army. Malnourished and untrained, this rag-tag group of soldiers fought fiercely against the imposing British Army. And even though they lost more battles than they won, George Washington’s Continental Army eventually prevailed. Their personal sacrifice ensured the preservation of our freedoms and led to the birth of our nation.

Since then, America has engaged in 10 major wars and fought in hundreds of battles around the world. Today, the Air Force, Army, Coast Guard, National Guard, Navy, Marines, and Space Force make up the 7 branches of the United States military. These are the men and women who proudly wear our country’s uniform to protect our freedoms. While their courage has always been recognized, there wasn’t always a day to honor our veterans.

The History of Veterans Day

The Great War, or World War I, ended on the 11th hour, of the 11th day, of the 11th month of 1918. The next morning, Germany signed the “armistice agreement” treaty with the Allies to finally end the war.

In 1919, on the one-year anniversary of the armistice, President Woodrow Wilson proclaimed “Armistice Day” as a holiday dedicated to the “cause of world peace”, and to honor the veterans of the Great War. Early celebrations included parades, public meetings and a brief suspension of business at 11:00 a.m. Armistice Day was celebrated by Allied countries Great Britain and France between World Wars. In 1938, Armistice Day was formally recognized by congress as a federal holiday to honor World War I veterans.

After mobilizing the largest group of soldiers in U.S. history for World War II, veteran organizations urged congress to expand the Act of 1938 to include all veterans. And in 1954, Congress swapped out Armistice Day and replaced it with Veterans Day. The newly-named holiday would honor U.S. Veterans of all wars.

Who’s Veterans Day for?

Veterans Day is a federal holiday to celebrate all veterans - living and deceased. However, Veterans Day is largely intended to honor living veterans.

Veterans Day is celebrated every November 11th. It’s a day to thank the people in your community for their service and acknowledge their time spent in the military. According to the latest U.S. Census Bureau in 2018, there were 18 million living veterans in the United States. Of those, about 500,000 served in World War II and around 600,000 served in the Vietnam War.

Many people confuse Veterans Day with Memorial Day. Memorial Day is a holiday that honors those who died while in military service who died while in battle, while Veterans Day is a celebration of both living AND deceased veterans.

Veterans in U.S. Presidential History

As the commander-in-chief, the President of the United States (POTUS) has full control of the nation’s military. And although a military background is not a prerequisite to take office, 29 out of the 45 presidents have served in some capacity.

From D-day to the Battle of Thames, U.S. presidents fought in many of America’s most pivotal battles and wars. In honor of Veterans Day, we’re ranking the U.S. presidents by their former military officer rank. From the lowest rank of private, all the way to six-star general, and everything in between. These are the presidents who served in our armed forces.

Paygrade Ranks

Before we get started, here’s a primer on enlisted and officer paygrade ranks. Newly enlisted service members start in paygrades E-1 through E-3 while in basic training or their initial assignment. Commissioned officers, O-1 through O-10, are the highest ranks in the military. These officers hold presidential commissions and are confirmed at their ranks by the Senate. Army, Air Force and Marine Corps officers are called company grade officers in the paygrades of O-1 to O-3, field grade officers in paygrades O-4 to O-6 and general officers in paygrades O-7 and higher. During times of war, the president may appoint a general to the rank of 5-star general with the paygrade of O-11.

After the Battles of Lexington and Concord, the Continental Army was formed and Washington was unanimously elected as commander. Washington would fight the British army for the next eight years, until they surrendered after the Battle of Yorktown. Afterwards, Washington relinquished his command and retired as a civilian, an inconceivable act at the time.
