U.S. Soldiers with the 1223rd Engineer Company, South Carolina Army National Guard and the 955th Engineer Company take apart a roof to deconstruct a building Feb. 18, 2014, at Kandahar Airfield, Afghanistan. The two units deconstructed more than 1,000 structures for closure and transfer during their deployment. U.S. and international forces in 2013 began the process of drawing down assets in Afghanistan ahead of the eventual transition to handing over Afghan security to Afghan forces.
