Ranger draw there lineage to Rogers Rangers of the Revolutionary war. They train based on Rogers principal of Rangers. Rangers have been reactivated throughout history... From the civil war, WW2, Korea, Vietnam and Today... After WW2 they are deactivated and and reactivated and restructured during the Korean war.
