 One of the more common means of exfiltration is by special operations helicopters.There are a number of techniques that do not require the helicopter to land, in which the SR team clips harnesses to ropes or rope ladders, and the helicopter flies away to an area where it is safe for them to come aboard.Small helicopters, such as the MH-6, have benches outside the cabin, onto which trained soldiers can quickly jump and strap in.
