CAMP LEJEUNE, N.C. -- Marines of the 24th Marine Expeditionary Unit are two steps closer to stepping off on their routine six-month deployment to the Mediterranean Sea after successfully completing their Amphibious Ready Group Exercise (ARGEX) and Supporting Arms Coordination Exercise (SACEX).During ARGEX, the MEU worked hand-in-hand with their Navy counterparts of the USS Nassau Amphibious Ready Group to conduct a number of missions to include several mass casualty drills, embassy reinforcement, Humanitarian Assistance (HA) operations, several raids and a Noncombatant Evacuation Operation (NEO).While during SACEX, the MEU fine-tuned its supporting arms fire capabilities by conducting several different fire support missions with the aid of 81 mm Mortars, AH-1W Super Cobra Helicopters, AV-8B Harriers and tanks.
