The Washington Post is reporting that the Iraqi resistance likely learned some of their bomb-making techniques indirectly from the U.S. Army. In 1965 the Army issued a detailed booklet on how to build and hide booby traps. The manual included detailed diagrams illustrating various means of wiring detonators to explosives. It also gave advise on the best locations for concealing deadly bombs. In 1987, Saddam Hussein distributed an Arabic version of the manual to the Iraqi military. The manual was translated at a time when the Reagan administration was supplying Iraq with military assistance in its war against Iran. One U.S. official estimated that ten percent of the bombs planted in Iraq use the pressure-detonation techniques detailed in the U.S. document.
