I was chatting with a friend about how to know what and who to avoid in terms of combatives training coursework and was asked about what separates good guys in the game. It was on the spot and the first thing that came to mind was if they were using marking cartridges or not.
There are a ton of former combat sports guys coming in the game with some interesting training. I think once the marking cartridges come into the equation though it will redefine much of what they're currently doing.
I say that because it was what happened to me. There were things that worked great with blue guns and inert tools that were terrible when I used nlta.
What do you guys say is the "one" thing?
