Okay, I see. Leap frog.
This is good WC/WT mentality. see look. (this is what hubbie teaches)
ex. man has a knife, I do not.
1. man jabs with knife to stomach, I shift my butt back to move stomach out of the way. At the same time deflecting the knife arm with gan sau movement.
2. gan sau moves knife arm across opponent's body away from mine you follow arm (touching not grabbing the knife arm) and your arm slides up their arm to tan sau all the way to their neck.
3. as you do this arm movements, AT THE SAME TIME, your stepping in a "lunge" position till the front of your body is totally up against their side.
4. here the knife arm is up, your arm is under the armpit in choke position at their neck. You don't have "control" of the weapon, you have control of the arm weilding the weapon.
5. here your stance is taking over their stance, thus unbalancing them with your legs as you "choke" or throw them with their neck and knife arm.
Of course, you stop the foot, kick the knee, knee the groin/stomach, grab the hair or helmet from behind, or gouge eyes all as you come into body contact and choke position with opponent. When they are taken to the ground, you stomp their face, throat, kick the head, always keeping contact with knife arm, you break knife arm, take weapon, etc. There is alot you can do here, and still be on your feet for a fire fight, or for the next soldier/attacker.
I ment that too many martial arts styles compete with the opponent's weapon, and focus too much on gaining "control" of the weapon and forget to attack the attacker. If I use JJJ I'd grab the knife wrist and try to manipulate a joint lock or forcefully move their weapon arm keeping it from me. While I do this, the opponent, punches, kicks, head buts, etc. Bot my hands are on one hand while they have another free hand. Not advantageous.
It's a different approach to fighting against an armed attacker when unarmed. This he learned in MCMAP as a third degree blackbelt in the USMC. But, he still applies WC/WT principles and concept of moving always forward into your attackers attack and space.
When we deflect a punch or weapon, we are NOT going backwards to defend, we are advancing as we deflect the attack and returning "fire" at the same time.
So, your deflection would be "team one" yelling "contact!" the deflection rushes forward to engage, your attack would be like "team two" yelling "move, move!" and backing up team one with fire.
p.s. I really wish the Army wasn't playing around with BJJ. It hurts me bad. They already don't get the quality time in training combatives like the marines do, and I'd wish they'd focus what little time they have to train on more productive modes of combat.
