Car Bombs as Weapons of War: ISIS's Development of SVBIEDs, 2014-19
The suicide vehicle-borne improvised explosive device (SVBIED) has been one of ISIS’s most powerful and versatile weapons. The group consistently adapted its SVBIED designs based on operational environment and other factors, with modifications in armor, payload organization, color, and detonation technology. ISIS’s research and development of SVBIED technology presents a continued threat, even after the collapse of the territorial caliphate, due to the group’s ability to share and export its designs, enabling nascent ISIS provinces halfway around the world to launch powerful attacks on unsuspecting communities.
