NCR riot control were NCR Veteran Rangers stationed at the Divide during the annexation by the NCR of the prosperous community of the Divide, acting as riot control. They used the former 11th Armored Cavalry Regiment riot armor only located there, which is a more advanced model of the riot armor used in NCR Ranger combat armor and the riot gear used by standard pre-War riot officers in the Divide. Riot control officers and the 11th Armored Cavalry Regiment convened there when the entire local hippie commune protested against the ongoing Sino-American War.
One NCR riot officer is in The Crow's Nest slumped over the window facing the High Road Entrance on the opposite side from the sniper rifle and ammunition boxes. He can easily be seen due to his riot gear standing out from the dusty wall beside him.
