My nominee for greatest USMC general is Holland M. "Howling Mad" Smith. Before the US entered WWII Smith was the most senior officer in either the army or the Marine Corps to have studied the problems of amphibious warfare and to have developed technological and tactical solutions for these problems. Except for Guadalcanal (which was begun on a shoestring) Smith led the earliest amphibious campaigns in the Central Pacific Theater, made himself a lot of Navy and army political enemies - not least for his having sacked a less-than-aggressive army general, but Smith proved himself and his prewar work on amphibious operations. Without him the Central Pacific campaigns might well have taken longer and cost more American lives than they actually took.
