Believe that^ training cant hurt. Theres lots of field manuals and speacial forces info to be found online for us civilians. Practicing run and gun drills. I didnt know how fucking hard it was to hit 10 yard targets when your hearts beating like a jackhammer, your out of breath and your adrenaline is pumping out of control. If your fortunate to have access to private land or public land, its good way to get into the outdoors and practice several senarios. Basicly just train like a soilder with the what you can learn online. One of the best information sources Ive ever found has been YouTube - nutnfancy's Channel

once again what can it hurt? for me its all the shit im into anyway, camping, guns, survival, hunting, just falls into place if you like outdoors I guess.
