"The PKM is a common enemy weapon that packs a wallop. It can penetrate our helmets. Untrained fighters typically will fire high during night time, or in places of limited visibility such as in the corn. Good fighters often use “grazing fire,” so that even when the enemy is lying flat the gun can get hits. During our ambush on 20 August, four days earlier, the enemy had used good fire discipline and it was only due to pure luck that none of us were killed. Our guys are better shots and more tactically sound, so whereas the terrain definitely belongs to the enemy, when firefights actually start, the smart money is on the Brits or Americans, not the Taliban. They might kill a few of us, but if they stick around and fight we will wipe them out."
Thanks for these
And that quote also sums it up nicely.
