B-021-331
From Halopedia, the Halo wiki
B-021-331 was a Brute Stalker who fought in a major skirmish between the UNSC and the Covenant forces during the Battle of Earth in 2552. He was killed by sniper fire, and his body was later recovered by the UNSC. His armor was relatively new, but other evidence, such as the many bullet scars on his torso, a dull bayonet on his Type-25 Spiker and a missing digit (finger) on his left hand proved that he was a veteran.
