This movie shows how Volume Breaker in TP works. It's still work in progress so I use only Volume Breaker.I'll add much more small debris,Fume smoke and so on.
For this TP set up, I referred Joe Scarr's and Hristo's method which we can see in their DVD.

I made some trigger particles on the body of tank then attach them. Wall also has a lot of trigger particles on the surface. When both tank's trigger particles and wall's trigger particles are close to certain distance, the cell particles and activation particles will born to activate VB. Then collision object of tank collide and push VB debris.
