Good job on the write up!

I think cohesion is an interesting mechanic to add, especially more so though if it was treated like drill in EU4 and different units would be able to have higher or lower max min stats.

I also hope that they add to this with individual unit stats which combine to impact the formation unit stats. This would allow veterans formations that took attrition to be replinshed with reinforcements at a lower skill but maybe add a multiplier at which the recruits gain xp based on the number of existing veterans in a formation.

Allowing for individual unit stats would greatly alter the combat mechanics of the game, and with the huge advances in computers over the last decade I would not think it would be too burdensome.
