Some well known Hollywood icons that served in the US Military.

11. Johnny Carson, U.S. Navy - The king of late night comedy was commissioned as an Ensign and sent to serve aboard the USS Pennsylvania towards the end of WWII. The very end. Like, the very last day: August 14th, 1945. But he did post an impressive 10-0 record aboard the ship as a boxer, and once performed a magic trick for the Secretary of the Navy, James Forrestal. After the war he served as a communications officer in charge of decoding encrypted messages. Yes, I know Ed McMahon had a more impressive military career, but he was a Marine and there's already too many Marines on this list. Plus, I always thought Johnny Carson being a badass boxer was pretty cool. Johnny died in 2005 at the age of 79.
