I studied KKW TKD and part of the teachings included lessons on using our skills against multiple attackers. When I promoted to BB I had to spar against 2 attackers at once. It was my understanding that the KKW required facing multiple opponents for Dan promotions. Do they still require this? Do other styles of TKD have similar requirements?
Yes - starting at BB ranks for free sparring, and at red belt ranks for step sparring.
