At UCLA, Compton participated in ROTC under Cadet Commander John Singlaub. In December 1943, he joined the Army and was assigned to E Company, 2nd Battalion, 506th Parachute Infantry Regiment in the 101st Airborne Division before Operation Overlord. During the company's action at Brécourt Manor, Compton and others, under the leadership of Lieutenant Richard Winters, assaulted a German battery of four 105 mm howitzers firing on Utah Beach, disabling the guns and routing the enemy. Compton was awarded the Silver Star for his action in disabling the guns. Episode two of the HBO miniseries Band of Brothers depicts this assault. During the battle, he threw a grenade that was said to have no arc and hit the German soldier on the back of the helmet. Later in 1944, Compton was shot through the buttocks while participating in Operation Market Garden, the Allies' ill-fated attempt to seize a number of bridges in the Netherlands and cross the Rhine River into Germany. The bullet traveled sideways, through one side of the buttocks and out the other side. After a partial recovery, he returned to E Company in time for the siege in the frozen Ardennes that became known as the Battle of the Bulge. Compton was evacuated for severe trench foot; Stephen E. Ambrose concluded that Compton had been "unnerved" by witnessing the carnage involving two of his closest friends, Joe Toye and William Guarnere. Compton wrote in his autobiography, "...although I was affected by the horrors of Bastogne, I do not believe I was clinically shell shocked, as the series portrays me. In real life, while I was hollering for the medic, trying to figure out what to do, I remember two distinct thoughts: How are we going to help the wounded guys?...Maybe this is the time the Germans are really going to get us all." In January 1945, Compton left E Company with an honorable discharge. He returned on VE Day for the company's annual baseball game. In 1947, he joined the Air Force Reserve, serving in the Office of Special Investigations and eventually Judge Advocate General Corps before retiring as a lieutenant colonel in 1970.

Later years
In 1946 he turned down an offer to play minor league baseball, choosing instead to concentrate on a career in law. Compton married Donna Newman in October 1947 and the couple adopted two children. He attended Loyola Law School in Los Angeles, joined the Los Angeles Police Department in 1946 and became a detective in the Central Burglary Division. He left the LAPD for the District Attorney's office in 1951 as a deputy district attorney, and was promoted in 1964 to chief deputy district attorney. During his time with the District Attorney's office, he successfully prosecuted Sirhan Sirhan for the murder of Robert F. Kennedy. In 1970, Governor Ronald Reagan appointed him an Associate Justice of the California Court of Appeal. He retired from the bench in 1990 and resided in the state of Washington until his death. Compton's memoirs, entitled Call of Duty: My Life before, during and after the Band of Brothers and written with Marcus Brotherton, were published by Berkeley Publishing on May 6, 2008. A celebration of Compton's 90th birthday was held in January 2012 with nearly 200 in attendance including Band of Brothers actors Michael Cudlitz, James Madio, Neal McDonough, and Richard Speight, Jr. McDonough developed a friendship with Compton while making the miniseries and kept in touch afterwards. McDonough's son Morgan is nicknamed "Little Buck" in honor of Compton.
