Camp Hathcock was a facility utilized by the UNSC, and located on the northern continent of the planet Reach. Nestled in the Highland Mountains, Camp Hathcock was a top-level retreat; heads of state, VIPs, and top brass were the facility's normal occupants, along with a division of veteran, battle-hardened Marines. After the battle of Sigma Octanus IV, Spartan-117, Captain Keyes, and several other members were debriefed here. Also the Spartans often ventured to the place during training.
It is possible that the camp is named after Carlos Hathcock. He was a legendary sniper in the Vietnam War and he went on to help train future snipers at the first official scout/sniper school. Hathcock held the longest recorded sniper kill for more than thirty-five years before his mark was surpassed in 2002 by Canadian Corporals Arron Perry and Rob Furlong - Furlong breaking his teammate's record mere days later.
