Bazooka/Shreck back blast

[kojusoki1]

Hi
I am wondering what is a back blast effect? I would like to deny bazooka/shreck placemnt in buildings - how can it be done?
I see back bust is "on" and we still can deploy bazooka/shreck in house... So what is the difference? Only animation?

Due to engine limitations the Bazooka/schreck must be able to fire from buildings.

The only mechanism available to stop fire from buildings means all shots are top of armour shots (like vetbob)  and so almost always record an instant kill.

Im not sure if i understand you properly - do you mean to set upper armour like 500mm of steel so shreck cannot penetrate this? And nobody will ever place shrecks in buildings becouse of that?
