With four months left in the year, 2010 is already the deadliest year yet for U.S. troops in Afghanistan. 321 have been killed so far (out of 485 total coalition deaths), compared with 313 deaths in all of 2009. As coalition troop size has increased, and moves have been made into Taliban strongholds, attacks are on the rise, and, according to General David Petraeus, "the footprint of the Taliban has spread". As combat operations in Iraq have now ended, the Obama administration says it will focus even more of its attention on the nearly 9-year-old conflict in Afghanistan. Collected here are images of the country and conflict over the past month, part of an ongoing monthly series on Afghanistan. This month marks the 12th entry in the series - I've been putting these together for one year now, and see no reason to stop any time soon.

During the operation the men spent two days in direct sunlight with temperatures reaching more than 120 degrees. The operation was conducted to disrupt the enemy from using supply lines to bring weapons and fighters into Nawa.
