If you find out the patterns of most efficient opponents you get a good idea of how to counter them!
Since you cannot test the whole world population, you can make assumptions on motions from martial arts and other sports to predict athlete's capabilities in reach, impact, and push and pull abilities. You add into the soup the reaction time formula and you are in!
Then you train your students in most efficient tactics of defense.
The training process has to have some sort of supervision even self in the worst case scenario assuming you have a good source. If you do not have a good source, then outside supervision might be worse than self supervision.
What do you do in the core Twenty-One hours of Pure Krav Maga training:
While the intensive five day course has about 30 hours of training, five of them are dedicated for comprehensive warm up. Another four to six hours(if the warm up only requires half an hour) are dedicated for extra drills for students that need it.
First you gear your mindset to be aware of opponent's intention by the way he advanced toward you. You then learn how controlling pressure points could reverse fortunes. Finally you then learn the to incorporate the invisible constraint of reaction time into your plan coupled with efficiency.
Second, you learn how to generate impact with a strike using the principles of momentum and sequential execution. You then learn combat motion meaning not projecting advance, simultaneously advancing and attacking, and where to optimize your stop after each attack and plan your next move.
Third, you learn to use your lower limbs in basic attacks and blocks.
Fourth, you learn blocks and counter attacks tactical entries into the hotzone.
Fifth, you learn how to block and counter kicks.
Sixth, you learn to generate impact with other hand strikes and elbows.
Seventh, you learn to generate impact with other kicks.
Eighth, you learn how to apply impact in the short and long range intuitively attacking and defending in sparring drills.
Ninth, you learn to use the close range forces of push and pull in optimal leverages, using the overall tactical approach preferring impact over push and pull.
Tenth, you learn combat motion in grappling scenarios rolling and breaking falls, attacking and defending from the ground.
Eleventh, you learn to use the close range forces of push and pull in optimal leverages, using the overall tactical approach preferring impact over push and pull on the ground.
Twelfth, you learn other restraining techniques and escapes.
Thirteenth, you learn to apply grappling escapes and counter attacks in sparring drills, and to combine them with the chain of defense starting from the long range.
Fourteenth, Fifteenth and Sixteenth and Seventeenth, you learn how to use a knife as a weapon. You learn how to use tactical entries into the hotzone against an attacker armed with a knife.
Eighteenth, and Nineteenth, you learn how to use blunt objects for attack and defense. You learn how to use your bare arms to defense against attacker using a blunt object.
Twentieth, and Twenty-first, you learn Pistol threat and Assault rifle threat defenses.
