Joe Louis: The heavyweight champion who enlisted

Joe Louis enlisted in the U.S. Army during his reign as heavyweight champion and staged 96 boxing exhibitions during four years of service.

President Reagan waved the burial requirements at Arlington National Cemetery for Louis after his death in 1981, and he was buried with full military honors.
