Many U.S. Presidents have worn the uniform, but World War II shaped more than most. Seven future commanders-in-chief put their ambitions on hold, stepping onto the battlefield to defend freedom. Some enlisted immediately after the attack on Pearl Harbor, while others left careers behind to join the fight. Their service revealed deep patriotism, proving they placed country before self.
Gerald Ford: From the Navy to the Oval Office

When Japan struck Pearl Harbor on December 7, 1941, Gerald Ford didn’t hesitate. He enlisted in the U.S. Navy, earning a commission as an ensign in the Naval Reserve. His early days were spent at the V-5 instructor school in Annapolis, Maryland, before moving to the Navy Pre-Flight School in Chapel Hill, North Carolina. There, he trained new recruits while coaching sports like swimming, football, and boxing.
By June 1942, Ford had climbed to lieutenant, junior grade, and within a year, he was promoted again to lieutenant. He soon joined the crew of the USS Monterey (CVL-26), serving aboard the light aircraft carrier through 1944. His duties placed him in the thick of combat, including operations in the Gilbert Islands, the Battle of the Philippine Sea, and invasions of Kwajalein, Eniwetok, Mindoro, and Leyte.

After surviving the deadly Typhoon Cobra, Ford was reassigned to the Navy Pre-Flight School at Saint Mary’s College in California, working with the athletic department. By April 1945, he transferred to Naval Air Station Glenview, Illinois, before leaving the service. Law school followed, leading him into politics, where he ascended from the House of Representatives to vice president—and ultimately, to the presidency in 1974.
John F. Kennedy: A War Hero’s Rise

John F. Kennedy once planned to attend Yale Law School, but war changed his course. A chronic back condition should have disqualified him from military service, but with the help of family connections, he joined the U.S. Naval Reserve. His first assignment placed him in naval intelligence, but he yearned for action. Determined, he trained for command and took charge of PT-101 on December 7, 1942, stationed near the Panama Canal.

Craving the front lines, Kennedy used his connections again to transfer to the Pacific. In April 1943, he took command of PT-109, a fast torpedo boat. That summer, disaster struck—his vessel was rammed by a Japanese destroyer. Two of his men died, but Kennedy led the survivors on a grueling 3.5-mile swim to safety. He later carved a rescue message onto a coconut shell, which reached Allied forces and saved his crew.
After recovering, Kennedy briefly commanded PT-59 before returning home due to health complications. His wartime experiences forged a leader, and politics soon followed. Elected to the House, then the Senate, he launched his bid for the White House, winning in 1960. His presidency lasted nearly three years before his tragic assassination.
Ronald Reagan: Hollywood Goes to War

By the time war arrived, Ronald Reagan was already a Hollywood star. He had joined the Army Reserve in 1937 but was called to active duty as global tensions escalated. Poor eyesight kept him from serving overseas, so he transferred to the U.S. Army Air Forces (USAAF), where he became a public relations officer. His talents were put to use producing training films—over 400 of them—helping shape the education of American troops.

Though his war experience was behind the camera, it deepened his patriotism. After the war, Reagan returned to acting but found himself drawn to politics. He became president of the Screen Actors Guild, later running for California governor in 1966. His landslide victory set the stage for his ascent to the presidency in 1980.
Richard Nixon: A Quaker in Combat

Richard Nixon’s Quaker upbringing could have exempted him from the draft, but he rejected an easy way out. Instead, he left his job at the Office of Price Administration to enlist in the U.S. Naval Reserve. Initially stationed at Naval Air Station Ottumwa in Iowa, he longed for a more active role. His request was granted—he joined Marine Aircraft Group 25 and the South Pacific Combat Air Transport Command (SCAT), overseeing logistics in the Pacific Theater.

Nixon’s duties led him to remote island bases like Bougainville and Nissan, ensuring vital supplies reached the front lines. By war’s end, he was stationed at Alameda Naval Air Station in California before being discharged in 1946. Politics soon beckoned, propelling him from Congress to the vice presidency. He eventually won the White House but resigned in 1974 amid the Watergate scandal.
Lyndon B. Johnson: Congressman at War

By the time the Japanese bombed Pearl Harbor, Lyndon B. Johnson had been a congressman for four years. As a Naval Reserve officer, he was called to active duty just three days later. President Franklin D. Roosevelt tasked him with assessing conditions in the Southwest Pacific, leading him to report directly to Gen. Douglas MacArthur in Australia.

While there, Johnson volunteered for a bombing mission. The plane suffered mechanical failures mid-flight, but Johnson’s composure earned him the Silver Star. Using his influence, he later pushed for improved conditions for American troops in the Pacific. Returning to politics, he climbed from the Senate to the vice presidency, ultimately taking over as president after Kennedy’s assassination in 1963.
George H.W. Bush: The Youngest Aviator

Born into privilege, George H.W. Bush had no obligation to fight. But on his 18th birthday, he enlisted in the U.S. Navy, becoming one of the youngest aviators in history. Flying the Grumman TBF Avenger, he saw action in the Pacific, bombing Japanese positions on Wake Island in 1944. That August, his plane was shot down over Chichijima. His crew perished, but Bush was rescued by the USS Finback (SS-230).

Despite the trauma, he continued flying combat missions, preparing for the invasion of Japan—an attack that never came due to the atomic bombings. After the war, he entered the oil industry, then politics. His career spanned multiple government roles before he won the presidency in 1988.
Dwight D. Eisenhower: The Supreme Commander

Unlike the others, Dwight D. Eisenhower was already a career soldier when war broke out. A graduate of West Point, he served under military giants like Gen. John J. Pershing and Gen. Douglas MacArthur. After Pearl Harbor, he was summoned to Washington, where Gen. George Marshall entrusted him with war planning. By 1942, he was Supreme Commander of Allied forces in North Africa, leading the invasion of Sicily and later masterminding the D-Day assault on Normandy.

Eisenhower’s leadership helped topple Nazi Germany. After the war, he documented German atrocities to ensure history would never forget. Popular with the public, he was urged to run for president. He won in 1952 and served two terms, leaving behind a legacy of strong leadership and military prowess.
World War II forged the character of many American presidents. Their time in uniform shaped their leadership, their policies, and their decisions. They weren’t just politicians; they were warriors who had witnessed the cost of freedom firsthand. And when the time came, they led their country not just from behind a desk—but with the conviction of men who had once fought for it.
