At least 858 U.S. soldiers have died in the Afghanistan war since President Barack Obama took office in January 2009. That equals 60 percent of the 1,427 American soldiers killed so far in the 10-year war in that country.
In March 2011, there were 26 U.S. military deaths in Afghanistan, including 4 non-combat related fatalities. That brought the total combat and non-combat deaths for 2011 (January, February, and March) to 70. Those fatalities include 57 combat-related deaths and 13 non-combat deaths.
Of the 858 U.S. deaths since Obama’s inauguration, 791 have been combat-related. This means that for the 1,241 combat-related deaths that occurred since the Afghanistan war began in October 2001, about 64 percent happened in the two years since Obama took office.
Last year was the deadliest for U.S. forces in Afghanistan, with 497 combat and non-combat fatalities. Improvised explosive devices (IEDs), or homemade bombs, continue to be the number one killer of U.S. soldiers in Afghanistan.
