20 years ago today, Medal of Honor recipient Cpl. Jason Dunham succumbed to wounds he sustained when he heroically dove on an enemy grenade – sacrificing his life for his fellow Marines.

In honor of his memory, Marines and Sailors with Marine Security Force Battalion Kings Bay host the Dunham Challenge each year, a rigorous fitness event held in remembrance of Dunham and his selfless sacrifice.

Chief Warrant Officer 4 Dustin Rose and 1stSgt Joseluis Mejia, two Marines who served in the same battalion as Dunham in 2004, speak on his character and his noble devotion to his Marines.
