A video recently posted to the Internet depicting an improvised explosive device (IED) attack in Syria has garnered a great deal of attention. A Syrian militant group called the Hawks Brigade of the Levant claimed the attack, which targeted a Syrian government armored troop bus as it traveled along a road near a rebel stronghold in the Idlib governorate. According to the group, the attack depicted in the video employed a type of IED called an explosively formed penetrator (EFP). Though the video was shot from a fairly long distance away, it does appear that the IED punched a substantial and focused hole through the armored bus -- precisely the type of effect that would be expected if an EFP were employed against such a target.
EFPs are a logical tool for militants to use against superior government forces that are heavily dependent upon armor. EFPs pose a significant threat to armored vehicles, which the Syrian military has utilized extensively, and quite effectively, in its campaign against Syrian rebel groups.
Studying the IED technology employed by a militant group is an important way to determine the group's logistics situation and trajectory. It can also be a way to discern if a group is receiving outside training and logistical assistance.
