Nice rant there skip licker.
Without knowing what the state of the CS they were engaging it is interesting but does reinforce the stereo type of the Talibs being a bunch of farmers with no major training or understand of basic marksmanship principals. The bloke at 01:43 firing over the large boulder appears to have been lucky not to get a face full when a round appears to ricochet a couple of inches in front of him.
An article I read regarding Taliban weaponry (I make no claims of accuracy here, mind) based on captured equipment effectively said that they were pretty much using junk. Of the dozen or so rounds left in the Talib's magazine, no two rounds were of the same origin. This isn't just mixing two batches together, but using ammo of years difference in age, from several different countries of origin, and likely with the bullets themselves differing quite a lot in true calibre.
Basically, I'd put good money on anyone using such a gun with that ammo not being able to hit a large barn if they were stood inside with the door shut. Since the Americans have helpfully bombed all the Taliban training camps repeatedly, I would wager that the extent of Taliban training at the footslogger level is learning basic AK-47 use and maintenance (put bullets in here, put magazine in here, point this end towards enemy and pull trigger) and remembering not to covert the arse of the commander's donkey. The only real problem is that AK-47s are cheap, bottom-grade ammo is really cheap and there seems to be an inexhaustable supply of religious pillocks willing to die for their god.
This is why they go for spray and pray shooting; they're young and know no better and the weapons won't hold an aim-point worth a damn even if they did try single shot aimed fire, so they splurge off all their ammo quickly then run for it. This too is moderately sensible behaviour in the circumstances; if you hang about after you've seriously annoyed a British patrol not only will you take aimed fire from the patrol, but you're going to face mortar fire, shelling, armoured vehicles or even an airstrike, and the people doing any of those can aim disturbingly well.
