Stardate 20011108.1100 (On Screen): Russia's traditional allies are General Winter and General Mud, and they were invaluable to the defeat of the Germans in World War II. Much has been made of the fact that the winters in Afghanistan are quite brutal, which is true, with the implication that General Winter will fight on the side of the Taliban. That may not be true. Winter affects everyone, and General Winter may favor us. One interesting fact about winter is that it makes IR imaging particularly effective. The greater the temperature differential, the easier it is to spot, and in winter the temperature differential between human activities and the background cold is particularly distinct. For instance, hidden cave complexes should be easier to find; regardless of how well hidden they are they must be ventilated, and the exhaust vents will cause heat plumes which can be spotted. Tanks in the winter must have their engines run periodically to prevent them from seizing up, but that causes heat and it can be spotted right through camouflage. The same thing applies to other kinds of vehicles. Infantry can't be as easily dispersed in cold weather because of the threat of hypothermia, and they'll be easier to find, because they'll be in a warm place, and to hit because they'll be concentrated. Moving supplies in the winter is difficult enough, but truck columns moving in the snow are particularly easy to spot even with normal cameras, let alone thermal imaging. All of those things can be bombed
And winter is not something which is a foreign concept to the US; some parts of this country have pretty severe winters. Our combat aircraft are designed to operate in extreme weather conditions, so there should be no difficulty in continuing the bombing campaign against the Taliban once the weather sets in. If anything, it should be even more effective. More important is that the 
10th Mountain Division is specifically trained and equipped to fight in foul weather. And elements of the 10th are already in that area. (discussion in progress)
