When doing Kempo we are going to start looking at the strategies behind the 2 man techniques.
This is the reason for the turns in the kata - accomodating where the next attack is coming from, often a simple technique done in an advanced situation with advanced distance and timing.
Moving away from or towards the next attacker.
We will then progress to the specific 2 man techniques.
A multi opponent sit, 3 or more, is almost entirely tactical.
Technique-wise you would deal with the current attacker and the 2nd man, who becomes the main man and the third attacker becomes the 2nd man, etc.
It is advanced and takes a lot of training to pull off.
