I dont have a big problem with trucks, but I think some more fun could be added. Make them do what trucks where suppose to do: carry stash!
As of now, once they have brought the men to the front, they are kind of worthless, except as vehicles that can be used for spotting for mortars/artellery, taking comand point, victory tokens etc. But I feel that there are several other fun rules which can be introduced in connection with trucks.
1 Ide: transport ammunation: For example, a hex could be determinded as the ammo-dump or something. Once a truck enters that ammunation dump, you recieve X command points. To recieve more command point, you have to move your trucks to design edge of the map (road hex maybe?) and return. Combined with an 'out of ammo' scenario could be fun. For example you could force one side to pay one command for every infanteri that fires, have them start with a limited command and the only methode of getting more command could be by securing a load of ammo from a truck?
2nd Ide: create a dex called SUPPORT II. Which works preaty much as the current version, except that a truck needs to drive to your men for it to be affective. One card can for example be to place a spesilization token below a truck which have droven of the edge of the map. The truck can then reapear on the map, and the token can be dumped anywhere, and can be picked up by any one of your squads.
3rd: Halftrucks and trucks should be able to transport AT guns along roads! But maybe only along roads. In combat situations, AT guns should obviusly not be as mobile as a tank, and thus limiting to only along roads only makes sence.
These are three idees to make trucks act as trucks.
