Very true. And there's a lot of discussions as to if it was an AK, whether or not it was full or semi-auto. As someone who's fired both, I think it matters very little. A Kalashnikov with a 30-round magazine is a very formidable weapon, even in semi-auto only. You can put a lot of lead downrange real quick and destroy targets in close quarters.
True. Ragheads may opt for full auto on an AK but in the hands of a capable infantryman I doubt they would feel the need to use full auto. Precise semi-auto firing will usually suffice.
