Which statement regarding VBIEDs is incorrect?

The rationale behind selecting that option as incorrect lies in the understanding of Vehicle-Borne Improvised Explosive Devices (VBIEDs) and the versatility of the vehicles that can be used. While trucks may be common for such purposes due to their size and capacity to carry larger amounts of explosives, it is a misconception to assert that only trucks can be employed as VBIEDs. In fact, virtually any type of vehicle, including cars, vans, and buses, can be modified or used for this purpose depending on the attacker's objectives and the desired impact.

This characteristic of VBIEDs, where different vehicles can be utilized, also ties into their potential for modification for specific operational purposes. Given that various types of vehicles can fit the VBIED definition, and that they should always be approached with caution due to the inherent risks involved, the statement about only trucks being used is definitively inaccurate.
