Most of my close friends from my teens and I train in various styles. Some TKD, a couple southern praying mantis, kung fu, kickboxing etc.
A few years ago we went on a stag do to Lithuania and to cut a long story short the night ended with us leaving a club with about 20-30 locals waiting outside who had a disliking to "non caucasians"
We numbered 11, and 7 of us train.
Once we got home and reflected, despite all the different styles, under these circumstances we all fought a similar fight to escape.
Simple hand techniques, with only 2 kicks thrown between us.
The non trained friends lacked the "calm/awareness" of the rest ( I remember one of the locals would tug at his jeans before throwing a kick ) often rushing in at the wrong time at the wrong groups of yobs to get knocked down. I remember dragging one friend off a yob he had ended up ontop of moments before a couple of locals rushed him from behind.
Despite 20yrs training at the time, I didn't have that natural "killer streak" like some of my mates to really "damage" some of the attackers but was calm enough see what was happening not just to me but to "back up" others that ended up on the ground.
Also getting hit alot in training means you're not phased as much by glancing blows in reality.
Can't comment on how it would have been in a 1 to 1 as I'm lucky enough to never have been in a real 1 to 1 encounter
