Our old pal FPS Russia has a strange idea of concealability. And reliability; 100-round mags are known for dependability in the same way as Agatha Lintott is known for her cleaning skills. Never mind. Let’s put that down to show biz. But when it comes to educating viewers how to use cover or concealment, Kyle could use a little education himself. Two problems here: efficiency and proximity . . .
First, you want to use (not “get to”) cover/concealment as quickly as possible. All you have to do: put the barrier between you and the threat. You could be 100 yards away (or more) and position yourself behind cover/concealment. You can then stay behind cover/concealment as you move closer—if you move closer.
The closer you get to cover/concealment, the less maneuverability you have. That’s both in terms of moving to a better firing position or more suitable cover/concealment, leaving cover/concealment to rescue a friendly and/or bringing your weapon to bear on the target.
Notice how FPS has to move slightly backwards after firing to the right of his cover. Notice how he puts the muzzle of his M16 over the barrier, making dropping back down much more problematic. We could also discuss the fact that the Internet’s favorite faux Russian’s shooting from his knees and firing his gun without aiming, but that would be churlish.
Let’s stick with this: knowing how to use cover/concealment is one of the most important skills an armed self-defender can learn. Especially as not getting shot is your number one priority. Shooting someone is simply a means to that end whether they’re dead or alive.
