While Linville is the first combat-wounded amputee to summit the mountain, New Zealander Mark Inglis was the first amputee to scale the storied peak, in 2006.
Linville joined the Marines in 2006 as an infantryman and deployed to Fallujah, Iraq, with the 3rd Battalion, 5th Regiment - known as the 3/5 "Darkhorse" battalion - in 2007, according to a biography on the Heroes Project website.
Upon his return he volunteered for explosive-ordinance disposal training and upon his certification as an EOD technician deployed to Afghanistan. He spent time in the volatile city of Marja before switching to a team in the bomb-riddled district of Sangin.
On January 20, 2011, Linville and his fellow technicians were investigating a roadside-bomb detonation when, during a sweep of the area, Linville triggered another bomb.
The device was probably laid to hit the Marines who were responding to the initial explosion. Linville's right foot and hand were riddled with shrapnel, and after years of surgery and rehab his foot was amputated in 2013.
