In recognition of Veteran's Day here is a representation of a few of the many actors who served our country in the military.
These are actors who served our country before, during or after their careers as entertainers. Sources indicate that these actors, (the majority being males) served before the Vietnam War. None can be found that served after, including after America was attacked on September 11, 2001.

James Maitland Stewart, even after his an active role in the military, Stewart continued to be active in the United States Air Force Reserve, achieving the rank of Brigadier General on July 23, 1959.
Jimmy Stewart did not often talk of his wartime service, perhaps due to his desire to be seen as a regular soldier doing his duty instead of as a celebrity. He did appear on the TV series, The World At War to discuss the October 14, 1943, bombing mission to Schweinfurt, which was the center of the German ball bearing manufacturing industry.
Eddie Albert
Prior to World War II, and before his film and television career (well known as Mr. Douglas on Green Acres), Eddie Albert toured Mexico as a clown and high-wire artist with the Escalante Brothers Circus, but secretly worked for U.S. Army intelligence, photographing German U-boats in Mexican harbors.
In 1942 Albert enlisted in the United States Navy and was discharged in 1943 to accept an appointment as a lieutenant in the U.S. Naval Reserve.
Eddie Albert was awarded the Bronze Star with Combat "V" for his actions during the invasion of Tarawa in November, 1943, when, as the pilot of a U.S. Coast Guard landing craft, he rescued 47 Marines who were stranded offshore (and supervised the rescue of 30 others), while under heavy enemy machine-gun fire.

Nancy Culp, actress best known as Jane Hathaway on televisions's The Beverly Hillbillies left the University of Miami to volunteer for United States Navy service in World War II, for which she received several decorations, including the American Campaign Medal, the National Defense Medal, and the Good Conduct Medal. (Tate's husband Roman Polanski)
Sammy Davis, Jr. served in the United States Army during World War II but was confronted by strong racial prejudice. Davis later was quoted as saying:
Overnight the world looked different. It wasn't one color any more. I could see the protection I'd gotten all my life from my father and Will (an "uncle" with the Will Mastin Trio). I appreciated their loving hope that I'd never need to know about prejudice and hate, but they were wrong. It was as if I'd walked through a swinging door for eighteen years, a door which they had always secretly held open."
