Let us pray

It'd look a hell of alot better if there was a tank on it to blow up aswell.
No one knows how to attach the tank to this trailer?
I need to know, A, B and/or C.
A. How to attach the static trailer to the static truck.
B.. How to attach the static tank to the static trailer.
C.... How to attach the "Armour" to the "Trailer" <--- That's the ones that aren't static, though the tank would be static sitting on the trailer of course. ( I know how to attach the truck and trailer that moves.)
