You will train against resisting opponents. You will train against multiple resisting opponents simultaneously. Then you will train against opponents with plastic knives and guns.

You are taught things like 'If your opponent is on the floor - keep kicking him - because then you look like a psycho and nobody wants to fight a psycho'.
