Ani and Epidauros fall, with Sparta and Varna set to follow. Brazil, like Iceland before them, has air superiority even on this front. A larger push by Brazil could probably secure control of the former Dvinnish Empire territory, and from there, the entirety of the Arabian peninsula. Remember when the Boers were confined to territory south and west of Dvin? Those were the days.
Incidentally - I’ve forgotten - has Brazil’s intervention meant that Arretium has yet another new owner, or has Brazil owned it before?
