So this guy is Captain America in real life. When war broke out after Pearl Harbor in 1942, Audie Murphy saw the armed forces as a way to help support his family and serve his country. He tried to enlist, but was still to young for the service. As soon as he turned 18 he went to the Marine Corps recruiter begging to join up. The Marines took one look at little Audie - he was five feet five inches tall and one hundred ten pounds - and determined that he was too small for the service. The Navy guys told him the same thing. The Army had no qualms about throwing Murphy into the meat grinder however, and shipped him off to North Africa as part of the US 3rd Infantry Division.
He played around in the desert in North Africa, then helped invade Sicily, then got medals for bravery on D-Day and in the subsequent liberation of France. His actions also got him promoted to Second Lieutenant. While fighting in the Holzwihr forest in January 1945, he was told to defend a critical pocket from the Germans with 19 men, all that was left of his 128-man company. Against two Nazi companies and six tiger tanks. And he did it, because he is Captain America. When Audie returned home, he was awarded the Congressional Medal of Honor.
He served some time in the Texas National Guard, retiring at the rank of Major. After his military service, Audie Murphy went on to be a badass movie action hero, starring in a number of Westerns and even playing himself in the autobiographical To Hell and Back. He was eventually given a star on the Hollywood Walk of Fame.
