Well looks like the Red Unit units fire the RPG, and not the Regular or any other unit, which is perplexing as I'm trying to get fired on by the RPG in my Clafghan missions. I reduced the cost to BIS values (along with the Weapons Pack), but the Red Unit RPG Gunner doesn't fire his weapon, he switches to the RPG and fires and hits me (just test mission, etc.) while I allow him to. Anyway so for now until you all know a trick with the AI (I can see if the cost works as 0.5 and go from there, but I don't know why that works). May be the values of the rifles, but we'll see.
