After the battle aboard the Pillar of Autumn, the Unnamed Corporal "Helljumped" to the surface of Halo when the ship crashed on Installation 04 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. She had words written on the circumference of her neck that read CUT HERE. The noncom and Hosky had been on the Master Chief's Warthog, when he took it to a structure. After the Warthog exploded, the Chief, the Corporal, and Private 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 hole the size of a dinner plate right through her after Hosky was killed. This brought the Chief personal grief for what he saw as his own fault.
