Thomas Pynchon served in the Navy.
Considering his monumental importance to American letters and literature in general, little is actually known about Pynchon, who refuses to be photographed and doesn't grant interviews.
One of the only confirmed photos of the author of such celebrated postmodern doorstops as Gravity's Rainbow and Mason & Dixon is from his two-year stint in the US Navy, which came in the middle of his four years at Cornell University in the late 1950s.
Pynchon's time in the Navy is evident in many of his major works: V. follows the misadventures of a recently-discharged Navy sailor in early-60s New York. Gravity's Rainbow, which takes place in World War II's European theater and revolves around Nazi Germany's V-2 missile program, is particularly rife with military-related themes and characters.

On an obtained personality appraisal sheet, Arthur was described as both argumentative and frank.
She was initially a typist in Washington D.C., and was then sent to air stations in Virgina and North Carolina. Arthur was honorably discharged in 1945 with the title of staff sergeant.

Norris, who had broken his shoulder a week into training, was on a walk when he observed villagers executing spinning heel kicks and other moves.
"I was mesmerized by their incredible ability. I wanted to ask them what they were doing, but they looked very intense," he said. "So I returned to the base and described what I had seen to my judo instructor, Master Ahn. He said it was called Tang Soo Do. I told him that I'd love to try it, since I couldn't do judo with my injured shoulder."
By the time he left Korea, Norris had his black belt in Tang Soo Do and brown belt in judo.

Elvis Presley was drafted in December 1957, and entered into the United States Army in March 1958 — two years after his songs "Hound Dog" and "Heartbreak Hotel" hit the airwaves and turned an unknown Mississippi boy into America's King of Rock and Roll.
“The army can do anything it wants with me,” he said. “Millions of other guys have been drafted, and I don’t want to be different from anyone else.”
Presley was stationed in Fort Hood, Texas before being deployed to the 1st Medium Tank Battalion, 32d Armor in Friedberg, Germany. It was there that he met his future wife, Priscilla Beaulieu.

Maynard James Keenan was once headed for West Point.
Before his long-form experimental rock band sold 12 million albums and garnered an obsessive worldwide following, the Tool frontman was an army enlistee hoping to get through art school on the GI Bill. He distinguished himself enough to make it into West Point's preparatory school and was even offered a spot in the prestigious US Military Academy — something that would have all but secured him a long, successful career in the armed forces.
Keenan turned it down. He finished out his enlistment, but songs like "Intolerance" — supposedly written about his time at West Point — betray a personal discomfort with at least some of the institution's values.

It was there that the then-lieutenant first began counseling his team and servicemen's families, a service that paved the way to further public speaking and "The Montel Williams Show."
When Williams left the Navy, he had received the Navy Achievement Medal, the Meritorious Service Medal, and the Navy Commendation Medal.
Montel continued to support sailors, marines and their families throughout his two decades on television, and was awarded The Department of the Navy Superior Public Service Award in 2008.
Kurt Vonnegut was a prisoner of war during World War II.
Those sections of Slaughterhouse-Five about the allied firebombing of Dresden drew from personal experience. Captured during the Battle of the Bulge in late 1944, Vonnegut was confined in a German prisoner of war camp near the city during the February 1945 aerial campaign. Some view the novel as an extended metaphor for what is now recognized as post-traumatic stress disorder.
Vonnegut received a Purple Heart for his service in World War II, along with three bronze service stars. The horrors he witnessed as an infantryman and POW would feed the simultaneously jaundiced and uncannily heartfelt view of humanity on display in novels like Breakfast of Champions and Cat's Cradle.

Sidney Poitier acted insane to find a way out of the Army.
After moving from the Bahamas to the United States as a teenager, Poitier had a hard time finding work. New York City's bitter winter temperatures were a drastic change of environment for the now Academy Award-winning actor.
So, in November 1943, at the ripe age of 16, he lied about his age and entered the Army.
According to the Los Angeles Sentinel, “The US Army literally took him in out of the cold.”
Poitier served as a medical attendant at a mental hospital in New York, but eventually grew tired of Army life. Instead of admitting his real age, he faked insanity, though he eventually came clean upon threat of shock treatments.
After talking to a psychiatrist for several weeks, Poitier was eventually granted release from the Army.
Clint Eastwood escaped from a sinking aircraft while serving in the Army.
Clint Eastwood got his acting start in Western flicks, but his time serving during the Korean War presented the actor with the adventure of a lifetime.
Eastwood was a lifeguard and swimming instructor at Fort Ord, eventually being promoted to corporal.
One night in October of 1951, Eastwood was on a Douglas AD-1 military aircraft that had departed from Seattle and was heading to Sacramento.
The plane's intercommunications system failed, forcing the aircraft to crash into the Pacific Ocean, two miles off Port Reyes. Though he had to swim to shore, Eastwood escaped serious injury.
"I thought I might [not] live. But then I thought, other people have made it through these things before," Eastwood said. “I kept my eyes on the lights on shore and kept swimming."
Jimi Hendrix's guitar-playing often distracted him from his Army duties.
When authorities caught Hendrix riding in stolen cars in Seattle, they gave him two options — go to jail, or join the Army.
So, in 1961, Hendrix enlisted and was assigned the 101st Airborne Dibision in Kentucky.
Though Hendrix had some success — he was awarded the Screaming Eagles patch after completing paratrooper training — his constant guitar-playing often kept him from his duties and drew criticism from fellow soldiers.
Hendrix was later discharged from the Army due to a ankle injury sustained in a parachute jump. The rest is Rock 'n' Roll history.
