Ah, it uses the weird 14.5mm caliber of machine gun? I think I'm using 14.5mm as the caliber for the heavy machine gun the Mechs can equip.

Probably end up using later models, then. Maybe. Not real sure...I really should try to keep to as few ammunition types as I can, but with the bugs having different thicknesses of exoskeletal armoring, I kinda need the variety...from a lore perspective. 

These vehicles will be made after the invasion, along with a lot of the mechs. I suppose weapons and ammunition will have been reverse-engineered, or the blueprints for such might have been taken into space.

I've figured that there should be facilities dedicated to military, medical, education, residential, agricultural...you know, the important stuff...
