Called Commando Krav Maga... It's a close combat system of the Israeli special forces (e.g. Sayeret, Yamam etc). There are other Krav Maga systems that are only taught to civillians and are no longer in use by the IDF (Israeli Defence Force) but I thought I would start to deal with my anger and un-spent aggression as well as get fit! The system is easy and quick to learn and is based on natural and simple movements that can be remembered - these are 'triggered' by the bodies natural reactions/responses, to attacks and threats, which means they work well under stress...apparently!! It took a week to be able to walk up the stairs after learning how to defend myself against a knife attack last week.... but last night I 'bit the bullet' was practicing dodging a punch then putting the attaker down!! Of course this meant I too was being 'put down'...ouch!!! I do enjoy it once I get over the first feeling of wanting to run out of the room and cry!
