S.P.I.E. is a system used to extract or instert teams very quickly, usually from hard to reach areas such as urban terrian or dense forest/jungles, to keep it plain and simple, S.P.I.E. is basically a long ripe that hangs from the chopper which teammates can attach themselves on to using their harnessess and carabiners, etc. Once attached, the chopper can lift off and move the team on the rope, it can also be used to insert the friendlies into hard to reach areas. the down side is the your teammates hanging on the rope are fully exposed to enemy fire... Now im unsure whether or not the the rope can be raised into the chopper, i'd figure yes, if not the chopper can set the troops on the ground. The other downside is that if the pilot isnt paying attention, his buddies hanging from his helo, may go "splat" on the side of a building... But i figure if fast roping can be added in, couldnt the S.P.I.E. system all be added in to...
You'll have to give me a while.
