Sorry, I forgot to answer this part of your post.....
how it differs from other styles of Krav if at all. Thanks.
It differs, in that it is designed to meet the needs of modern combat. In example, it is based on gross motor skills and as Itay says "correct bio-mechanical movements". The point being, if a soldier has a 90lbs. pack on his back, the skills still work. If an officer is wearing body armor and has a full duty belt on, they still work. If a person is attacked in the middle of a long jog and they are exhausted, it still works. If the attacker is aggressive and/or skilled, it still works - etc.
The difference is once again in the gross motor skills. We use methods which allow our entire body to secure a weapon weilding limb, we don't just grab the muzzle of the gun in one
hand and expect that the bad guy will let it happen without a fight! Here is a VERY short (10 Min) demo which may help illustrate what I mean: www.cottonwood-combat.com/tuitionandshop.aspx
