As of Monday, at least 3,308 members of the U.S. military have died since the beginning of the Iraq war in March 2003, according to an Associated Press count.
Baghdad, Iraq Over the past six months, American troops have died in Iraq at the highest rate since the war began, an indication that the conflict is becoming increasingly dangerous for U.S. forces even after more than four years of fighting.
From October 2006 through last month, 532 American soldiers were killed, the most during any six-month period of the war. March also marked the first time that the U.S. military suffered four straight months of 80 or more fatalities. April, with at least 58 service members killed through Monday, is on pace to be one of the deadliest months of the conflict for American forces.
Senior American military officials attribute much of the increase to the Baghdad security crackdown, now in its third month. But the rate of fatalities was increasing even before a more aggressive strategy began moving U.S. troops from heavily fortified bases into smaller neighborhood outposts throughout the capital, placing them at greater risk of roadside bombings and small-arms attacks.
Roadside bombs have long been the No. 1 killer of American troops in Iraq. Since October, officials said, insurgents have been employing more sophisticated devices, with the most lethal results coming in Baghdad. Nearly 38 percent of military deaths since October have occurred in the capital, compared with 29 percent over the previous 12 months, according to the Iraq Coalition Casualty Count (http://icasualties.org), an independent, U.S.-based Web site that monitors military and civilian casualties.
At the same time, insurgents are leaving Baghdad to escape the crackdown, and in recent weeks U.S. and Iraqi troops have launched major operations outside the capital. Some of the heaviest fighting has occurred in Diyala province, northeast of Baghdad, where 44 American service members have died so far this year - more than in the previous 22 months combined.
In the past, U.S. fatalities had a tendency to spike in months of heavy combat, then drop to lower levels in subsequent months. April 2004 and November 2004 were the deadliest months of the war for American forces, due mostly to intense combat in Iraq's western Anbar province.
But those high death tolls quickly dropped; for example, the death toll in April 2004 was 135, but fell to 42 two months later. The November 2004 toll was 137, but dropped to 58 in February 2005 and 35 the following month.
The past several months, however, have brought the longest period of sustained heavy casualties since U.S. troops entered Iraq in March 2003. December saw 112 soldiers die, the most since November 2004, and the subsequent three months registered 83, 80 and 81 fatalities, respectively.
Under the new security plan, Baghdad has supplanted Anbar as the deadliest region for American forces. Of the 58 deaths so far in April, 34 have occurred in the capital. The figures include all deaths, not just those that the military says occurred due to hostile action.
