The 0307 Expeditionary Ground Reconnaissance (EGR) Officer MOS is a secondary MOS for Officers assigned to the Marine Corps' Reconnaissance Battalions in each Marine Division.  Primary MOS's for these officers are 0202, 0203, and 0302.


EGR Officers are the commanders or their assistants in the reconnaissance battalions and force reconnaissance companies. As such, EGR Officers plan, direct and assist in the deployment and tactical employment of reconnaissance units. To fulfill these responsibilities, they evaluate intelligence; estimate the operational situation; and formulate, coordinate and execute appropriate plans for ground reconnaissance, amphibious reconnaissance, raids, fire support, special insertion and extraction, communications, operational logistics and maintenance. EGR Officers are also responsible for the discipline, morale and welfare of their units' Marines.
