Gal Gadot
Superwoman has a pretty super story. Since Gal is from Israel, she was drafted into the army at the age of 18. All Israeli citizens are required to join the service when they come of age for a period of time. While there, Gal took the position of a combat instructor. She also taught gymnastics and calisthenics to other soldiers. After her time was up, she moved to the US to pursue acting.
Jimi Hendrix
Did you know that this guitar legend once served in the military? At age 19, he was arrested for driving stolen cars and was given the choice of serving in the military or going to jail. He chose service and was sent to Fort Campbell, Kentucky. He was there for eight months until his platoon sergeant discharged him because "Private Hendrix will never come up to the standards required of a soldier."
