I trained under Jason Epps here in Edmond. First off there is a big difference between martial arts and combative martial arts. It's all in the manner it is taught. Are you being trained to win a tournament or are you being trained to escape a situation as fast as possible while taking the minimum damage needed? I haven't been to Oklahoma Combative. However, under Jason Epps, we trained in muay tai, BJJ, judo, karate and so on. In addition to those, we did train in krav maga. I think it is the most relevant training to real world events. We trained to engage multiple attackers at once, firearms defense, knife assaults and a variety of different weapons. It was intense. While I will agree that it takes practice to become "great" at it, it doesn't take alot to become very good at it. Krav is simple if you work hard at understanding it an can become second nature in a hurry. I will also disagree with the 9 times out of 10 the larger stronger man wins the fight. I am 175lbs and about 5'9", not big by any means. Constantly in class I was paired with guys 250lbs, some fat and some muscular as hell. I will happily take on the bigger attacker every time. The mistake all of them made was "I'm was bigger than this guy, I'll over power him". It didn't work out like that. Most of them did not fair well. When someone is properly trained and is confident in their abilities it gives you the edge over someone who just feels dominant. I've seen the smallest of women in class take out the biggest of men. If you're learning and training properly, you'll figure out it's not about how big or how strong you are. I know these classes were the MMA variety, but there were no punches pulled. You went into a combative situation. I would highly recommend Krav Maga to anyone.
