Bare ass is not his idea of a good joke, although I can certainly see how it would sound. It is a term used to refer to jumping without equipment (rucksack, rifle, vest/webbing or snowshoes etc). I would have to agree wholeheartedly that a bare ass ramp jump is sweet, it is pretty hard to screw up and you will get a perfect opening almost every time. As far as double door, mass exits with full equipment, which is what is depicted in that ROTC video, in the para company that is what we do more than anything else. It is considered the most likely method of operational deployment (the US dropped 1000 paratroopers into Northern Iraq this way recently) so it is what we practice the most. The method of exit we use in the CF is called a 'JAB' which ideally will give you a good strong exit and minimize some of the brutal exiting you can see on that video. A proper bare ass JAB exit involves aggressively throwing your static line towards the aft end of the aircraft, a strong stomp with the inboard foot to drive you through the door while adopting the stance of being doubled over at the waist, chin on the chest, thumbs behind the reserve, elbows in, feet and knees together. All of that becomes a little harder to do with any finesse as you add more and more equipment and the end result can seem more like a waddle and then tumble (there are some differences also in the JAB when involving a shoulder load/weapon). Although I have never been to the US Airborne School, I have jumped with them on a number of occasions and it has always seemed to me that the Americans tend to just run out and hope for the best. My sweetest exit of all time has got to be bare ass from a Griffon, 2000ft. over DZ fluffy pillow (Anzio).
