I think they should add both the sticky bomb and the Panzerknacker (Hafthohlladung) to the game.
One was basically totally useless, the other Extremely deadly irl.
The Hafthohlladung as a shaped charge weapon (HEAT) was totally deadly.
I would like to see these type of models added in leu of the Ubiquitous TNT fantasy bundles we have.
But I would prefer they be modeled realistically.
