Unidentified corporal

The Unnamed Female Corporal was an Orbital Drop Shock Trooper under Major Antonio Silva.

Battle of Installation 04
After the ferocious battle aboard the Pillar of Autumn, she dropped to the surface of Installation 04 when the ship crashed on it like all the rest of the Orbital Drop Shock Troopers. During the Battle of Installation 04, the unknown Corporal had been on the search for the Silent Cartographer with SPARTAN-117.

The noncom and another Helljumper named Hosky had been on the Master Chief's Warthog, when he took it to a structure, where they encountered a pair of Hunters. After the Warthog exploded, the Chief, Corporal, and Hosky sprung into action. The Corporal threw a grenade at a Hunter, and watched it explode with no effect. Soon, Ogada Nosa Fasu blasted a large hole right through her chest, immediately following Hosky's death. This brought the Master Chief personal grief for what he saw as his own fault, as he should have explained to them the probability of fighting a Hunter.
