Niko is a master at Krav Maga, a fighting style used by Israeli Special Forces.
This made me happy, because I know Krav Maga and that shit will save your life.
Its gun/knife disarming and basic attack/defend.
If I ever get around to it I'll post some videos for gun/knife disarming.
I'm eager to see how this plays out in the game.
Basically what that means, if they acutally utilize Krav Maga, is plenty of headbutts, knees to nuts, elbows to throats and so on.
And obviously disarming/taking enemies weapons from them.
