Saw this in the blog today:

Hayes is unequivocal in naming the key to the 24th MEU's success in Helmand province: "It's a real simple concept -- we learned during this mission that the best way to combat this type of enemy is to mass forces and stay. We actually replaced a small British force that was spread thin trying to cover too much ground with too few troops. Instead, we flooded a town that was strategically important to the enemy with overwhelming forces. That's the way you can win this kind of fight -- with boots on the ground."
It seems to work in A-Stan too.
