A top U.S officer says the military is beginning a massive building effort in Afghanistan to house the roughly 20,000 additional troops, including an undetermined increase in Marines, that are expected to begin pouring in early next year.
Maj. Gen. Michael Tucker, deputy commander for operations for U.S. forces in Afghanistan, told Pentagon reporters that military leaders are anticipating a "very active winter" of insurgency attacks.
U.S. defense officials have said they will build up the number of forces in Afghanistan as soon as they are able to free up troop commitments in Iraq. Commanders in Afghanistan have said they need four more combat brigades, along with thousands of support forces, including intelligence, surveillance, aviation and logistics personnel.
One brigade is expected to arrive in Afghanistan in January. Three others have not yet been identified.
