Raise seats and secure them. Seats can be left secured emplace (down), this causes all jumpers to execute a 90 degree turn around the last cargo seat at the paratroop door. (This method of exiting must be rehearsed.) A 90-degree exit is vital due to the absence of an air deflector. Immediately after putting the seats up (if applicable), the jumpers must tighten down their appropriate adjustable leg straps and secure the excess webbing in the webbing retainer when jumping combat equipment. When the command of “HOOK UP” is given, the jumpers will detach USL snap hook from the top carrying handle of the reserve parachute. Hook up to the anchor line cable with the opening gate towards the skin of the aircraft. Jumpers will form a bight (four in the hand, two below). Jumpers will not touch the double-sewn portion of the USLM. The first three jumpers will extend their static line arms to obtain the proper distance between jumpers. All others will hold their static line elbow high.
