Airborne rappelling
A mountaineering technique of descending with a climbing rope from a VTOL aircraft. A person on rappel uses friction or mechanical breaking devices to control the descent. To rappel from an helicopter is an average air assault skill roll. In many cases a helicopter is unable to land at a properly cleared landing zone. Therefore airborne rappelling techniques are employed as a means of inserting a patrol into an area of operations to conduct operations. This form of insertion is also effective for Visit Board Search and Seizure (VBSS) and Close Quarter Battle (CQB) missions where time is of the essence. Equipment for these operations is simply the individual's operating gear, the rappel lines, and Swiss seat harness, carabineers and rope gloves. Helmets and goggles are used for protection.
During the procedure the helicopter hovers at about 30 metres altitude while the troops slide down ropes to the ground. If the character fails this roll then they will fall to the ground. The character will have one chance to catch himself by making an average air assault skill roll. If this roll is failed then the character will complete the fall. If the character rolls a critical failure when repelling the rope snaps and the character will fall to the ground.
