Good job gaz, hopefully that picture will enlighten some people. Even if in the perfect world utilization of this little thing called logic should have made this incredibly obvious to everyone already.
One thing I'd like to add:
Cover is cover as long as it stops bullets, you don't have to be touching it, in fact, that is the last thing you should do, because cover can be exploded and then what are you going to do? Nothing, thats what, cause you're dead!
Another thing that happens when you get too close to cover is you expose your position, seeing muzzle flashes and weapon barrels becomes substantially easier when they're pointing out of windows or out from behind corners.
Shadows are also a concern, but almost only when facing enemies with high to extreme awareness.
(the kind of people who notice if the same car passes by their window twice in a row and in what timeframe, not because it's a red mitsubishi though. They remembered the license plate)
In conclusion: The operator should stay as far away as possible from cover to increase his/her area of domination and decrease likelihood of detection.
Also, consider the possibility that what you're using as cover may occasionally be
on fire, covered with
sharp sticks or the
Ebola virus.
This guy knows what I'm talking about.
