The animated points displayed on the map represent every roadside bomb and improvised explosive device (IED) attack between 2004 and 2009. Coalition forces continue to battle this unconventional warfare technique that has resulted in 66% of the casualties in Afghanistan since 2001. There has been increased effort to study the use and origins of the IED in Afghanistan. Geography has proven itself to be one such answer, both the physical and human geographic element. The central highlands of Afghanistan form part of the Himalayan chain which sequesters itself from the more populated lowlands. Encircling the highland region is Asia Highway 76 and Highway 1, also known as Ring Road that connects Peshawar, Pakistan to nearly every densely populated city in the country.
