Abstract:D6297 This paper is a historical analysis of the U.S. Marine Corps' new concept for amphbious warfare, operational maneuver from the sea (OMFTS). The paper examines the history of amphibious warfare from 1941 to the present in order to provide a general assessment of the relationship between OMFTS and historical reality. The major argument of this paper is that the stated premises underlying the OMFTS warfighting concept, while largely sound, are incomplete. OMFTS neglects important historical constraints and demands on amphibious warfare. Consequently, OMFTS should be refined into a more realistic and pragmatic concept.
