I wish to see truck that can tow the heavy gun to the frontline.
They are considered to be towed during the operations phase of a campaign.
Russian cavalry are abstracted the same way.They are assumed to be riding horses during the operations phase(hence greater movement) but are considered dismounted during the tactical phase.
During a battle the trucks are assumed to have moved away to a safer location.
I would like to see trucks tow guns in the tactical phase also.
Maybe one day we will see this in a future DLC.
