A recent article in Strategy Page explains how the Marines are adapting to the new rules of engagement in Afghanistan designed to limit civilian casualties:
The U.S. Marine advance into Helmand province is being slowed down by the new Rules Of Engagement (ROE), which forbid the use of bombs or missiles in any situation where there might be civilians. The Taliban will typically spend the night, or longer, in a village or walled compound, and that's where U.S. troops will typically trap them. But bombs and missiles cannot be used on these places, so U.S. troops have to besiege the place, or just move on, leaving the Taliban alone.
Some marines get creative, like having the jet fighters or bombs make a high speed pass over the Taliban held buildings. The fearsome noise will sometimes unnerve the Taliban and cause a surrender, but not as much as it used to. Another favorite tactic is having the fighter (usually an F-16 or F-18) come in low and use its 20mm cannon. But these air craft only carry a few seconds worth of ammunition. Moreover, having these jets fly that low makes them liable to crashing (this has happened, at least once) or being brought down by enemy fire (has not happened yet). But the cannon fire sometimes induces the Taliban to give up, or try to flee.
The other option, when you have the Taliban cornered, and using human shields, is to go in and fight them room-to-room. That gets more Americans killed, as well as putting the Afghan civilians in danger. This room-to-room tactic has not been used much, as commanders don't want to take the heat for losing troops in that kind of fighting.
If there is a lot more of this house to house fighting, and civilians get killed, the ROE may be changed again to forbid any kind of combat if civilians are present. This reduces the anger of locals from civilian deaths involving U.S. forces, but makes it much more difficult to hunt down and destroy the Taliban gunmen. The Taliban are still vulnerable, as they have to move in order to operate, and the Afghan Army or police can often negotiate a surrender, or go in and root them out by force. But the best troops available for chasing down the Taliban gunmen are the U.S. and NATO forces.
The rules are appropriate. Curtailing civilian deaths is not only the moral thing to do it will also pay off in the long run by diminishing resentments among the people whose hearts we must win if we're to have any permanent success.
Even so, coalition casualties are rising, partly due to the new rules and partly due to the increased tempo of operations in Helmand Province. One sign that the media has recovered from the swoon it suffered at the thought of an Obama presidency will be when they start reminding us every day how many Americans have died in Afghanistan since Mr. Obama was inaugurated.
