Marine Staff Sgt. Mark Zambon was a bomb disposal technician in Afghanistan, on his fourth deployment doing that dangerous job, when he stepped on a bomb while on patrol in Helmand province in 2011.

Both his legs were severed above the knees, among other injuries. While recovering from the life-changing loss, Zambon was determined to avoid self-pity and self-doubt and dedicated himself to honoring two buddies who were less lucky than he was.

Zambon climbed Mount Kilimanjaro on prosthetic limbs, wearing the dog tags of two Marines who were killed while working on the bomb squad: Sgt. Mike Tayaotao and Staff Sgt. Josh Cullins.

Watch his unique homage in the above video from CBS' 60 Minutes, whose news team followed Zambon and other awe-inspiring veterans who have taken up a sport that is dangerous for even the most seasoned athletes.
