The number of Iraqi army battalions judged by their American trainers to be capable of fighting the insurgency without U.S. help has slipped from one to none since September, Pentagon officials said Friday. But the number of Iraqi battalions capable of leading the battle, with U.S. troops in a support role, has grown by nearly 50 percent. And the number of battalions actually engaged in combat has increased by 11 percent. The Pentagon report to Congress was written last week, before the bombing of a Shiite shrine and a wave of deadly reprisal attacks.
