This is NUTS. The members of the Armored Combat League get dressed up in medieval armor and go at it, hard. Like full on with knives and axes and clubs.
We've seen guys' fingers get cut off, we've seen guys' knees kicked in, we've seen guys break both of their arms in the same fight, we've seen guys get all their teeth knocked out because the helmet smashes up against their face or something, some guy had to get flown out by helicopter because he has blood in his brain...
Makes movie fighting seem a lot more like dancing, doesn't it? (thx, byrne)
