Asking about possible uses like that for NPCs is part of combat, and so has not been determined yet. It would make more sense that they couldn't use weapons out side their main category (projectile for riflemen etc) as otherwise there would be less reason to buy different versions - just train and apply skill points into multiple categories for one NPC type.
“just train and apply skill points into multiple categories for one NPC type.”
But then your would be diluting the effectiveness of your NPC. Example:
-I have an NPC with a skill of 1 in projectile weapons, and 1 free skill point. I apply the point to projectile weapon skill, so now he has a skill of 2.
-You have an NPC with a skill of 1 in projectile weapons, and 1 free skill point. You apply the point to heavy projectile weapon skill, so now he has a skill of 1 in each.
-Our NPCs face off in battle armed with the same projectile weapons. My NPC stomps your NPC since my projectile weapon skill is better. Your NPC might be able to use heavy weapons, but that does you no good since it doesn't come into play in this battle.
It'd probably still be ok, but the whole idea of specialized NPCs is that they start off
with some skills, and can possibly have extra skill points to add.
If you buy a rifleman and use his unused SP on non-projectile weapons skill,
then he'd be worse off than a melee combat trooper that had it's SP put towards
it's non-projectile weapons skill. That's why it'd be dumb.
Indeed. On the other hand, you only need to pay (or will do) one NPC, and you would get the versatility of 2 categories in just one NPC. In any case tis all up to the admins at the end, when they code it.
