are able hit less protected areas. It has been estimated by the Washington Post that as much as 64% of U.S. deaths in Iraq occurred due to IEDs. IEDs have also been used extensively by other groups, such as Maoists in India, ISIL in Syria and across the world, and by the Liberation Tigers of Tamil Eelam (LTTE) in Sri Lanka. Land mines Land mines have been used extensively by insurgents throughout Cold War and post-Cold War conflicts such as the First Indochina War, Vietnam War, South African Border War and conflicts in Iraq, Syria and Yemen by insurgents as a method of area denial, psychological warfare and attrition. During such conflicts, minefields are never marked and are used for more than defensive purposes, and are also placed singly over a less wide area. Land mines were commonly deployed by insurgents during the South African Border War, leading directly to the development of the first dedicated mine-protected armoured vehicles in South Africa. Namibian insurgents used anti-tank mines to throw South African military convoys into disarray before attacking them. In the areas of fighting that covered vast sparsely populated areas of southern Angola and northern Namibia, it was easy for small groups to infiltrate and lay their mines on roads before escaping again often undetected. The anti-tank mines were most often placed on public roads used by civilian and military vehicles and had a great psychological effect. Mines were often laid in complex arrangements. One tactic was to lay multiple mines on top of each other to increase the blast effect. Another common tactic was to link together several mines placed within a few metres of each other, so that all would detonate when any one was triggered. To discourage detection and removal efforts, they also laid anti-personnel mines directly parallel to the anti-tank mines. This initially resulted in heavy South African military and police casualties, as the vast distances of road network vulnerable to insurgent sappers every day made comprehensive detection and clearance efforts impractical. The only other viable option was the adoption of mine-protected vehicles which could remain mobile on the roads with little risk to their passengers even if a mine was detonated. South Africa is widely credited with inventing the v-hull, a vee-shaped hull for armoured vehicles which deflects mine blasts away from the passenger compartment. During the Iraqi, Syrian and Yemeni civil wars, landmines have been
