U.S. troop casualties highest in Sunni areas
Security
(McClatchy Newspapers) Sunni Muslim insurgents remain by far the biggest threat to American troops in Iraq, despite recent U.S. claims that Iran is providing Shiite Muslim militia groups with a new type of roadside bomb, a review of American casualty reports shows.
While U.S. military officials have held briefings to publicize their concerns about the potent bombs known as explosively formed projectiles (EFPs) or penetrators, casualty reports suggest that such weapons in the hands of Shiite militias are responsible for a relatively small number of American deaths.
U.S. officials have said that attacks with such weapons increased 150 percent in the past year. But a review of bombings by location shows that less than 10 percent of attacks that killed at least two American service members in the past 14 months were in areas where Shiite militias are dominant.
Those reports show that fewer than half the bomb attacks on heavily armored U.S. vehicles such as Abrams tanks and Bradley Fighting Vehicles were in areas where Shiite militias dominate. While it's difficult to know which armed group planted a bomb, analysts say the casualty numbers show that U.S. officials are exaggerating the importance of EFPs, which military officials say have been used only by Shiites.
"There were relatively few American deaths from explosively formed penetrators until recently, but you can say the same thing about attacks on helicopters or chlorine attacks," said Loren Thompson, a defense analyst with the Lexington Institute, a policy research group in Arlington, Va. "The fact of the matter is that the insurgents, both Sunni and Shiite, are becoming a lot more sophisticated in their tactics. Explosively formed penetrators are only one part of that, and they are not a particularly important part."
Pentagon officials say the issue is important because the Iranian government appears to be involved. "I think the issue is not whether or not materials and supplies are coming from Iran - they are - but rather how far up the Iranian leadership is involved," said Bryan Whitman, the Pentagon's chief spokesman.
U.S. military officials accuse Iran of supplying Shiite militants with EFPs, which fire a molten slug of metal that can punch through the thickest American armor, including tanks and other vehicles designed to withstand heavy blasts. The officials say the bombs have killed at least 170 U.S. and allied service members and wounded more than 620 since they were first discovered on the battlefield in mid-2004. "Explosively formed penetrators are not some exclusive franchise for the Iranians," Thompson said. "They are fairly common around the world."
Explosively formed penetrators are also known as shaped charges. The warheads were developed after World War I to penetrate tanks and other armored vehicles. Rocket-propelled grenades and antitank missiles are conventional examples. Shaped charges also are used in the oil and gas industry.
John Pike, the executive director of GlobalSecurity.org, an online clearinghouse for military, intelligence and homeland-security information, said that while designing a shaped charge would require expertise, fabricating the devices was simpler, requiring only skill in using metal-machining tools. Asked who'd have the expertise to manufacture a shaped charge, Pike cited "people who had worked with explosives in the petroleum industry." In Iraq, he said, "there would be a fair number of those."
U.S. military officials say EFPs are more dangerous than other types of roadside bombs because they typically produce more casualties. American casualty reports show that the deadliest roadside-bomb attacks of the war have occurred in predominantly Sunni areas or areas with mixed ethnic and religious populations.
