jungle penetrator - A three armed anchor like seat, lowered by winch and cable from hovering helicopter down through the jungle canopy, with the arms folded up against the cable to permit it to penetrate the vegetation.  It would often pick up quite a static electricity charge and had to hit the ground to discharge before you grabbed it. Two or three men could sit on the arms, when extended and hook straps around their backs to be winched up out of the jungle into the waiting helicopter.
