I think their biggest was when they vaporized a cement truck.
beyond amazing - I didnt think it possible
I had a keen interest in that episode because I drive a concrete mixer, the hours and days immediately after 9/11 I carried my Beretta 92 with me when I made deliveries because we were advised of a possible threat of truck hijacking to use a mixer for truck bombs.
The trucks I drive are 10-12 cubic yard capacity, that translates to 40-48,000 lbs. of material they can haul.
That much explosive in a single mixer truck would be the size of a small tactical nuke.
