There was the problem, someone dug it up as a wish for the new version (?), of the game being unable to model tandem HEAT warheads on non-ATGM weapons.
That drives out several existing weapons like RPG-7V, RPG-29, several Carl-Gustav rounds, and gun tandem rounds if these exist.
So I was thinking about a small and probably feasible recoding, that is creating another HEAT version with a corresponding reference code (say 223 instead of 222) which will give it the HEAT-tandem (anti-ERA) capability instead of AP.
That kind of thing would work for any weapon class and allow for all kinds of tandem-HEAT projectiles, including the kind of fire-on-move Listy is considering, with a high accuracy value (guided rocket like).
Of course it would need code work, so this is just a proposal!
