The Heavy Incendiary Explosive Gun Emplacement has been used by the Coalition of Planets for 22 standard years. It is refitted and remodeled every year, so the 22 on the latest model signifies its length of service. With a well placed shot, entire platoons can be disenagrated and or blown to bits with the 200 mm HIE round. Main pic is what you DON'T want to see...It is also the worst of these pics, all else of which I think are phenomenal for my standards!
