The Overwatch Elite is a specialized, higher ranking Overwatch Soldier, sporting a distinctive white uniform and helmet. They are the deadliest of the combine infantry. Elites are tough, have better accuracy, and inflict more overall damage then regular soldiers do. They are typicly armed with the Overwatch Standard Issue Pulse Rifle.

Elites typically fight in squads of their own kind, but will occasionally operate with regular Overwatch Soldiers or, in rare cases, Hunters. They are generally reserved for more critical combat missions, where their deadly skills and efficiency are required. They also serve as Wallace Breen's personal guards in the Citadel. One of them takes the Gravity Gun from Freeman when he later arrives at Breen's office in the Citadel.
