Hand to hand
I have been a fan of Gru Spetsnaz for a while now. The problem That I have though, is when it comes time to use these skills I usually revert to the basics and the most effective techniques. Nothing fancy like Bruce Lee or anything. In terms of weapons I have found that I have a strange attraction to my K pot or my E tool. Also if you have a firearm such as a rifle without ammo, you can still give butt strikes and barrel pokes which hurt alot, trust me.
