[Mobhack]

Vehicles with a large cannon as weapon 1 usually do have smoke shells assigned and based on unit class as do mortars etc. (Dont look at Mobhack if that was what you were looking at - it is done in internal unit creation code, not read from external data).

See the "X" key for firing these, and the unit information screen under "smoke ammo" for how many shells and S/D are currently left.
