We consider NFL players to be heroes in the loosest sense of the word and the military personnel heroes in the truest sense. The former are well-paid athletes who sometimes lead a lavish lifestyle but do sacrifice years of preparation to entertain us. Then there are the military personnel who are ready to sacrifice their lives to keep us safe.We look at some players who began in the military. Note that this list does not include many honorable people who began as NFL players and then transitioned to the military like the great Pat Tillman. Here we only look at such heroes who were in the military before playing in the NFL.Military personnel who played in the NFL#1 - Chuck BednarikChuck Bednarik was drafted into the Army at the age of 18 and was a World War II veteran before joining the NFL.
