So if you are going to muck about with weapons why don't you give most AP & HE as use kinetic armour & HEAT for plasma or some such that can be shielded. So stuff with no shield has both armours the same & stuff with shielding has high HEAT armour to represent. Or work something out with ERA armour setting it to 8 or 9 so it protects well for a few hits. Biggest Warhead size you can for tactical nuke or area effect weapon perhaps with limited shots. Or a weapon that causes very low casulties but major suppression in an area. Use truck movement (not 4WD) for stuff without good cross country ability etc etc.
Can't see how you can go about modding without at least scanning docs to see how things work mind.
