Rocky Bleier: Drafted in the 16th round of the 1968 NFL draft, Bleier figured that he would be sent to the National Guard or Reserves like many of the other NFL draftees, but he was instead sent to Vietnam with the 196th Light Infantry Brigade. Bleier was hit by rifle fire and grenade shrapnel, and informed by his doctor that he would never play football again. However, he eventually returned to become the Steeler's fourth all-time rushing leader and winning four Super Bowls with the Steelers.

Heywood remained in the Marines for 32 years before retiring as Colonel. He is the only NFL player to have served in World War II, Korea, and Vietnam. Heywood passed on in 2007.

Volunteered for a tour in Vietnam where he served as a supply officer. Staubach returned to the NFL in 1969 and would eventually play in four Super Bowls - winning two - and be inducted to the Hall of Fame.

On July 20, 1967, the C-123 plane that Steinbrunner and five other airmen were flying on was shot down, killing all on board.
