“Your job is to first move the barrel away from your body. You need to train your body to make the minimum movement with only your hand reaching the barrel and deflect it before you do anything else. You may swivel your body to point the barrel away from you if the gun is pointed at your back. You definitely do not want to stare at the gun, showing your intention to reach for it. That might make your attacker shoot you, being afraid that you will try to take it. Take into account that your attacker is not going to give up his weapon. You will move in the direction of your attacker. If he tries to pull his hand back and aim again, you should have already gotten a grip on his weapon. Consider that he can use his free hand or his legs to strike or kick you as well. Once the barrel is not pointing at your body, follow immediately with a simultaneous counterattack. Finish by acquiring the weapon. I will show you gunpoints at various angles with their respective defenses. However, if the angle and body position is slightly different, keep in mind the following advice where order of priority is concerned. First, your mindset should be to use the short time you have without thinking too much about the dangers. If you do, you may be dead mid-thought. Second, you need to move the barrel away from your body without projecting your intention. If the barrel is poking your body, you may need to use your body to swivel away, or deflect the opponent’s wrist instead. Third, you need to attack your opponent to buy time and gain control of the hand holding the weapon. I will show you a technique that will combine all your needs into continuous motions. You need to attack your opponent until you feel he loosens his grip and resistance. You can then extract the weapon out of his hand. Fourth, you need to be conscious that the barrel is not pointed at any innocent bystanders if possible. And you need to be ready to use his weapon immediately, or use your body to handle additional attackers. If you do not, you may have wasted your time and your life. And finally, after you have extracted the pistol, move away from the opponent so he will not be able to reverse your fortune again. Do not hesitate to shoot him if he tries to reach you. If his weapon does not function, you can still kick. Your attacker may have other weapons in his possession. Be alert!”

“You need to learn to identify the danger and move fast, taking advantage of the short window of opportunity. Note that you have to do it while training your body in quick chain reactions. Consider your opponent’s capability in using straight attacks from a greater distance and circular attacks from a shorter distance. If the starting point is from a greater distance, and your opponent has paused for a moment, you might have time to move your whole body and meet him halfway either with a kick or a hand defense. If the attacker is lunging forward with a straight stab, start with throwing your forearm toward his wrist and pulling the rest of your body away. Land forward as you counterattack and then try to grab his wrist for further control and safety. At this point, you control his arm and he cannot use the blade against you. If your opponent is attacking with a straight stab, it would be faster for him to lunge with the blade forward than for you to move your body out of the way. Yet remember that with a straight stab stance, he can lunge and stab you from two to three steps away in a split second. Stand still and just deflect his knife-holding wrist with the inside of your forearm by spinning it inward. Your arm motion will pull your torso at a horizontal forty-five degree pivot. Immediately after, deflect your opponent’s wrist, and fall forward as you can plan your landing position while in motion. You can also grab his retracting hand at its exit point, not giving him the freedom of movement. Remember that you are looking to strike him with your free hand at the same time. If, during training, your opponent or training partner knows what to expect from you, he will pull his arm behind his back so you cannot grab his wrist. Punching his face will foil any attempts to bring his arm back and try to poke you anywhere in your body. Obviously you can hit him lightly to buy yourself a second or two and then grab his arm. Or, you can hit him lightly again until you get control over the knife. If you are caught by surprise from a short distance and you manage to see the motion of a hand, but you don't have time to determine whether the hand has a blade or not, your blocks should be instinctively directed to your opponent’s wrists. You should counterattack with your free hand immediately after. If you see that your opponent is or might be holding a knife, you can kick and stop him before he plans to stab.”
