Warsong Elite

Warsong Elites are Mag'har orcs located in Kor'kron Vanguard in Dragonblight.

Speculation
They are likely a part of the Warsong Offensive as the other NPCs standing nearby but given they are brown and thus from Outland, they could also be from the Warsong clan. However, the clan, except for Garrosh, was not encountered in Outland.
