Someone brought up ammo and field weapons with infantry. For AS they may not track ammo but for TW games it is one ton per weapon. Field Guns can use rapid fire rules as well as different specialty ammo. They do not, however, explode. Field Artillery can also use any ammo a normal artillery unit can, though I would advise against a Davey Crocket at short range. The MUL has very few of either as well as others have discovered. Best to make them in MML and print the RS (which is getting an overhaul).
