Do you retrain?

[sanitarium]

It's well known that the AI rarely retrains with the exception of with alex.exe. So in a lot of ways if you're playing with any other executably, it's effectively an exploit in favour of the human player.

It's also, IMO, pretty unrealistic too, given you can restore a veteran unit with a handful of survivors right back to it's old effectiveness. And in only a season, doing the same with potentially several units at once.

I wouldn't say it's an exploit just because the AI doesn't use it, it's still a legitimate game mechanic. It'd be kind of like calling naval invasions an exploit since the AI rarely if ever does them (at least, not coordinated invasions).

When I retrain a veteran unit, I almost always lose chevrons. Especially when there are only a handful of men left; I've seen silver chevron units drop to 1 or 2 bronze.
