An international terrorist organization is planning an attack during the Thanksgiving Day parade in New York City this year. The organization has created a front through a local religious organization that allegedly supports the Thanksgiving celebration and has secured a position in the parade for two floats. The floats will actually be vehicle-borne improvised explosive devices (VBIED).
What are these forms of delivery of high explosives? What is the typical target for such attacks? How can you mitigate and prevent such attacks as well as develop proper response strategies knowing that the offenders probably have established secondary and tertiary concerns as well?
Your response should be at least 200 words in length.
