August has been the deadliest month for the U.S. military in the entire Afghanistan war.
As of this afternoon, 51 American servicemembers have been killed in Afghanistan this month. That breaks the previous record set only last month when 45 Americans were killed in July.
With four months to go, this is also already a record year for American casualties in Afghanistan -- 182 U.S. servicemembers have been killed so far this year, compared to last year's 155.
