“On March 29 [2003], soldiers from Scott Rutter’s US 2-7 Infantry Battalion had stopped a taxi at a checkpoint. When the driver opened the trunk so it could be inspected, the vehicle exploded, killing four of Rutter’s soldiers as well as the driver and charring a passenger bus on the other side of the highway. It was one of the first unambiguous cases in which the U.S forces had been attacked by a suicide car bomb–and a harbinger of some of the guerrilla tactics to come.”
