It should have greater AOE/Damage against infantry, maybe have a HEAT shell with increased pen ability for a couple seconds to get off one shot for AT that costs 40 muni or something.
The smoke shell fires too slow and it gets caught on things in the way occasionally (something I've not seen happen with other tank smoke shells).
Is the game being updated anymore with unit changes?
lets give the command panzer laser rangefinder and the L/55 smoothbore gun of the leopard 2A6 as well, 30 rounds a minute and AoE of three 152mm guns at once
+ the smoke behaves as with other (ukf) smoke shells do
