Jason Dunham
The last recipient of the Medal of Honor(posthumous), the highest possible military award. A Corporal in the Marine Core, Dunham was part of 4th Platoon, Company K, 7th Marine Regiment, 1st Marine Division, 1 Marine Expeditionary force during Operation Iraqi Freedom. Dunham died April 22, 2004. 8 days before, when an enemy grenade was thrown into his unit, Dunham selflessly put his Kevlar helmet down on top of it and threw himself down on top of it, saving the lives of many other Marines. For this, he was awarded the Medal of Honor.
Cpl. Jason Dunham was one of the bravest people I've heard of.
