A Sept. 30 checkpoint shooting in eastern Afghanistan's Wardak province brought the US military's death toll in the war past 2,000, by official count. A report by the Brookings Institution (PDF) estimates that 40.2% of US deaths were caused by improvised explosive devices and 30.3% by gun attacks. The independent organization iCasualties estimates a higher US death toll, recording 2,125 to date. This same source reports 1,066 deaths of non-US coalition troops in Afghanistan. (BBC News, Sept. 30) Note that the US military death toll reached 1,000 in 2010—a grim indication of how the rate of US casualties is growing. The death toll for Afghan civilians last year alone topped 3,000—lives claimed by both insurgent and coalition forces. Afghan civilian death (at that point mostly at the hands of US bombardment) topped 3,000 by the end of 2001. The figure, poetically, is the same as the death toll from 9-11. 

The US military death toll in Iraq reached 4,000 in 2008, and currently stands at 4,486 according to iCasualties, with the total coalition death toll at 4,804. The combined US death toll in Afghanistan and Iraq surpassed 3,000 in 2006.
