Oooooooh! Good idea! I say it was your inventor who defected to Arcis since it's a nation built on immigrants banished peoples, so it would make sense. How about the inventor, for reasons we will discuss later, defected to Arcis, gave them the tank designs, then help develop the new, unique "Arcis Rounds" to give the tanks a greater edge? Oh and upon learning this, let's just say our nations relations are going to be quiet the cluster fuck. XD
