Currently almost all of the anti tank guns and anti aircraft guns that engineers built are the same, Germans always use Pak38, Soviet always use 53K, with the exception of Battle of Berlin, in which all of the anti tank guns are Pak40 even the Soviet Union use Pak40. This creates a problem, those guns are OP againts lower tier tanks like Pz.II and BT-7, but ineffective against Tigers and Panthers.
I heard all of the campaigns will merge into research trees. Why not add another research tree for those stationary guns?

Besides those guns built by engineers, it would also be interesting to have stationary guns in the map that allows players to use.
