War of the Suns. Chinese War of Resistance 1937-45. Rules Reinforcements & upgrades/reductions.

Must admit I normally like the approach of replaced counters with better units (when they have new designations - like in most East Front games), or, at higher level, when their DRM changes, like in Unconditional Surrender. But, considering how many different types / factions you have here, it would make sense to add extra counters to mark upgrades.
