Special Operations Craft – Riverine craft perform short-range insertion and extraction of special operations forces in river and near-shore environments. The SOC-R is designed so that the boat including its tractor and trailer fits aboard C-130 or larger aircraft. Special Boat Teams (SBT) perform an insertion/extraction delivery system called MEATS. MEATS allows an Army MH-47 helicopter to carry a SOC-R rigged to the underbelly of the helicopter with slings. The Combatant-Craft Crewmen use a rope to get from the helicopter onto the craft for insertions, and a ladder dropped down from the helicopter to get off the SOC-R craft when extracted. It replaced the Patrol Boat, River, and the mini armoured troop carrier.
