The US Marine Corp has always been a physically fit group of people, but modern warfare has required them to be ever more so. Many of the enlisted are trained by Major R.E. Hanley, better known in some circles as former Northwestern University football coach Dick Hanley. He uses many of the same training techniques he used to train his all-American football players. Other marine training is demonstrated, such as one-on-one combat. Marines are still required to perform formal duties, hence they still learn traditional maneuvers such as drills.
