A Question That Has Been Asked Before But Needs To Be Asked Again

Here is the thing, groups like Cobra, GI Joe, the A Team, the Stormtroopers, and the Foot Soldiers are supposed to be these elite soldiers/warriors/mercenaries. You ask any character within their universe, and they will tell you they are precise shooters and war machines. Which now leads me to my question. Were these guys specifically trained to miss all their targets? Is it some type of elaborate military strategy that an outsider like myself will never understand? Did they just like to fire a lot of warning shots?

Or did the fictional universes they reside in, just have really low standards for what a precision shot is?

Speaking of imprecise, this was a lot more than the one question promised in the subject header. What can you do?
