Historically, there is nothing new about IEDs. Explosive booby traps, now termed Victim-Operated IEDs, were used extensively in the latter part of World War II, usually put in place by retreating troops. In the early years of the occupation of Germany, booby traps used extensively by former SS and paramilitaries opposing the occupation caused significant Allied personnel losses resulting from tactics such as suspending piano wire or steel cable across a road to decapitate personnel in open jeeps, staff cars or on motorcycles. In South Vietnam, the VC and NVA used IEDs extensively, often making use of UXO (unexploded ordnance) after bombing raids. One available statistic credits around one third of US casualties in Vietnam to the use of Warsaw Pact supplied land mines and VC/NVA IEDs. Arguably, the most refined users of the IED prior to the post Cold War Middle Eastern users were the IRA in Northern Ireland who used a range of devices, primarily remotely initiated to attack Royal Ulster Constabulary and British forces. Roadside or buried bombs used against vehicles – remotely initiated and later initiated by the interruption of an infrared beam – were a favourite tactic and accounted for serious losses. The unfortunate historical reality is that the conflict between the IRA and Britain brought about significant evolution in IED technique, a tradecraft that has since contributed to turmoil globally. Conflict in the Islamic world is where the IED rose to major significance, used in Afghanistan against the Soviets and more recently by the Taliban, in Lebanon by the Hezbollah, in Iraq by Al Qaeda, local insurgents and militias, and in Chechnya by fundamentalist separatists. The IED has displaced most other weapons, and its effect dominates casualty statistics. The attraction of the IED is that it allows an opponent to be attacked, often remotely, not exposing the operator to the superior firepower and tactical skills of a modern infantry force. IEDs can be divided into several categories, including roadside or buried bombs, effectively improvised land mines, suicide bomber vests worn by 'martyrs' who provide a 'not so smart bomb' delivery system, vehicular car bombs, static or driven by a suicide bomber, and a variety of directional or shaped charge IEDs. In principle, any explosive weapon not originated from an industrial production line may be classified as an IED. ieD explosives anD construction There is considerable diversity therefore in the configuration and size of IEDs, …
