The last several years have seen a sharp uptick in car bombings both in Syria and Iraq. It is no coincidence that this spike has coincided with ISIS's growing influence in the region. Car bombs are often created with many of the same explosive components that you find in IEDs. Think of a car bomb as an IED, but just on a larger scale. The ATF estimates that a compact sedan could potentially carry 500 pounds of explosive and pack a lethal air blast range of 30 meters. The spike in car bombings has also meant a surge in home grown car bombers. Training schools (including one discovered outside of Baghdad earlier this year) run by ISIS have sprung up to teach operatives how to build car bombs.
