Corey-067

Petty Officer, First Class Corey-067, born Corey Ullson, is a SPARTAN-II supersoldier of the UNSC Naval Special Warfare Command. Even among his fellow Spartans, he is renowned for his heightened reaction times, even without his Mjolnir Armor, contributing to his success in close quarters combat. He has a notable affinity for dealing with computers and machines, a talent he used to great effect in ambushes against both Covenant and Insurrectionist targets. As of 2558, he is one of the few active Spartan-IIs. He had participated in 197 operations - 119 of which were full campaigns - as of August 2558. 
Corey, like all of the Spartan IIs, was taken from his home at the age of six and brought to the planet Reach, where his life changed forever. He had struggled against his captors, breaking the nose of one of them before they were able to sedate him. His new environment was very much harsher than anything he’d ever experienced, and he wanted to go home. They told him that his parents had agreed to his being there and that they wouldn’t be coming for him. 
He formed strong bonds with a handful of his fellow Spartans, and worked with those Spartans as often as he could, during training.
