Soldiers of 1st Platoon Charlie Co. of the 2/87 Infantry Regiment, 3rd Brigade 10th Mountain Division based at COP Sayedabad take over an empty house as they conduct an air assault on the village of Lachikhel in the Tangi Valley in Wardak province, Afghanistan Friday June 5, 2009. Raids on villages such as this one are part of the "Clear, Hold, Build" strategy commanders are implementing: instead of harassing and hunting insurgents, they hope to marginalize them through close engagement with the population.
