Cochran
From Halopedia, the Halo wiki
Private Cochran is a member of Corporal Harland's veteran squad. During the Battle of Sigma Octanus IV, Cochran and his squad encountered Hunter units, and was wounded by a Covenant Grunt's Needler. Cochran's wounds however did not stop him from saving his squad by shooting down pursuing Covenant Banshees with Walker's Jackhammer launcher.
