improvised explosive device

homemade bombs and jury rigged explosives used to destroy vehicles or personel

I have seen police vehicles in the states do the same things also if you look (at least with the quality of this video) they appear to be nudging them lightly enough it doesn't even damage the bumper on the cars plus if you notice many people just get out of the way as the humvee drives through I doubt they just did this without warning I am sure there was a notification given more vehicles moved out of the way then got hit in the video
