who is playing vs elite ai?

[Imp]

Just my view but you would be better of selling your units & buying new ones to keep experience sensible, If you want a rational for this your elite guys are transfered to fight beside raw recruits & keep them alive. Still want an advantage keep your Company Leaders.
You can start with some of your army as conscripts & change them to regular when they reach 70 or so if desired.
You cant buy 100 exp units in the game let alone higher as in reality they dont exist, nor is the game really set up for them as they become super human.
If however you want to explore the game engine go ahead
