Vehicle borne IEDs (VBIEDs) can include which of the following vehicles?

Vehicle-borne improvised explosive devices (VBIEDs) can indeed include a wide variety of vehicles, which is why the correct answer encompasses all the provided options. VBIEDs are defined by the use of a mode of transportation that is capable of carrying explosives into a target area.

Cars, trucks, and buses are frequently used because they are common, easily accessible, and can be modified to conceal explosive materials effectively. This makes them a practical choice for those intending to carry out such attacks. Boats and airplanes also have the potential to be used as VBIEDs, especially in scenarios where targets might be located in or near bodies of water or air travel routes.

By recognizing that any vehicle capable of transporting explosives can serve as a VBIED, it becomes evident that the broadest categorization, including all the vehicles listed, is the most accurate. Thus, each type of vehicle can be utilized depending on the circumstances and the specific attack strategy.
