It always good to read about insurgents tactics.
“Afghan insurgents can be brave and tenacious, with a gift for small unit tactics. They have frequently engaged US and NATO forces directly, often for long periods, and made effective use of fire and maneuver, including flanking and encirclement. At times, they have pinned down patrols and closed in for the kilL They have launched hundreds of attacks on fortified bases and raised the costs of maintaining these positions by targeting Coalition supply lines with IEDs and ambushes.”
