A very good update. It left a lot of questions to be answered.
I agree with OdinMage, I think you have your martial arts disciplines backwards. Let them do Aikido and then move them into Krav Maga, now that IS offensive martial arts!

I’ll say it again, one must learn to walk before one learns to run. Judo is that walking. Aikido is…walking very fast. I learned Krav Maga while I was in the sandy part of the world with the Marine Corps. It is designed to ensure not only that your opponent goes down quickly, but that he doesn’t get back up. Let’s just say we don’t want them killing anybody. For most situations, like schoolyard bullying in Britain, Aikido (Hell, Judo, for that matter!) is all they need.
