MOS Description and Mission

While every Marine Officer may be a rifle platoon commander, Infantry Officers are selected through a grueling process to be the warfighters and leaders in charge of Marine Corps infantry units. This is the largest officer MOS with over 2000 Infantry Officers on active duty. Infantry Officers are the commanders or their assistants in infantry and reconnaissance units in Marine Air-Ground Task Forces (MAGTFs). They plan, direct, and assist in the deployment and tactical employment of MAGTFs and any subordinate infantry and reconnaissance units. Infantry Officers are responsible for the discipline, morale, and welfare of their unit's Marines. To fulfill these responsibilities, they evaluate intelligence; estimate the operational situation; and formulate, coordinate, and execute appropriate plans for offensive/defensive maneuver, reconnaissance, fire support, nuclear, biological and chemical defense, directed energy warfare, communications and operational logistics and maintenance.
