Harrier II are flown by off of Navy amphibious assault ships, while the F-35C Lightning II and F/A-18 Hornet are flown off of Navy carriers by Marine Corps pilots. The Marine Corps also operates the KC-130J to serve as a tanker and tactical airlift platform. The UH-1Y Venom helicopter provides the Marine Corps with light transport and attack, while the AH-1Z Viper is a dedicated attack helicopter. Medium lift squadrons fly the MV-22 Osprey, while heavy lift squadrons use the CH-53K King Stallion. The Marine Corps has also begun flying unmanned aerial vehciles, such as the MQ-9 Reaper and MQ-8 Fire Scout. Notably, the aviation combat element also includes Low-Altitude Air Defense Battalions, which employ the FIM-92 Stinger surface to air missile. The smallest MAGTF is the Marine Expeditionary Unit (MEU), which are typically forward deployed on Navy ships. Commanded by a colonel, a Marine Expeditionary Unit consist of 2,200 marines split across a battalion landing team (ground combat element), composite helicopter squadron (aviation combat element), and a combat logistics element (logistics element). Marine Expeditionary Units are supplied for 15 days. Forward deployed Marine Expeditionary Units are often embarked on Navy amphibious assault ships as part of an amphibious ready group. The next sized MAGTF is the Marine Expeditionary Brigade (MEB), which are organized for specific missions. Commanded by a brigadier general, Marine Expeditionary Brigades consist of 4,000 to 16,000 marines across a Regimental-sized ground combat element, a Marine Aircraft Group, and a Combat Logistics Regiment. Marine Expeditionary Brigades are supplied for 30 days and offer increased firepower and airpower over the Marine Expeditionary Unit. The largest MAGTF is the Marine Expeditionary Force (MEF), which are primary warfighting forces for larger operations. A Marine Expeditionary Force is commanded by a lieutenant general and consist of 46,000 to 90,000 marines. Currently there are only three Marine Expeditionary Forces, each with its own Marine Division, Marine Aircraft Wing, Marine Logistics Group, and Marine Expeditionary Force Information Group. Marine Expeditionary Forces are supplied for 60 days.Certain elements are held at the Marine Expeditionary Force level, such as Force Reconnaissance. The MEF Information Group (MIG) also provides a number of functions, such as the intelligence battalion, radio battalion which conduct signals intelligence, electronic warfare, and cyberspace operations, communications battalion, the MEF support battalion, and the Air Naval Gunfire Liaison Company. While not a MAGTF, the Marine Corps has begun to reorganize some of its
