Hosky

Private First Class Hosky was an Orbital Drop Shock Trooper stationed aboard the UNSC Halycon-class cruiser in 2552.

Battle of Installation 04
He "helljumped" to the surface of Halo when the ship crashed on Installation 04 like all the rest of the Orbital Drop Shock Troopers. He was part of First Lieutenant Melissa McKay's unit, which was in turn part of Major Antonio Silva's Battalion of ODSTs, stationed aboard the Pillar of Autumn.

During the second day of the Battle of Installation 04, he accompanied the Master Chief during the assault on The Silent Cartographer. He rode shotgun on John-117's Warthog during his second run to the map room. As they neared the front door of the facility, two Hunters attacked before the Marines could run for cover. Hosky and the Corporal were then both killed by Ogada Nosa Fasu, with Hosky being killed by getting rammed by Fasu's shield and having his face crushed by the heavy boot of the Hunter.

This brought the Master Chief personal grief for what he saw as his own fault, as he thought that he should have anticipated the possibility of the Hunters.
