Attrition..

[george585]

I don't think there is a way to script the removal of small portions of units. I remember an attempt to simulate loss of troops to weather, desertion, etc on the RTW engine but it just couldn't be done quite right. The best option was to script a plague and that didn't even work.

I am by no means an expert, but using console commands it is possible AFAIK to remove units from the army and then add them again with different number of troops. It's a technical trick (instead of dicreasing the number of troops in a unit, you are simply removing the unit itself, and then adding it back but with fewer troops). I suppose it would be possible to retain all the experience and armor upgrades by checking the original unit's stats, and then applying them to the new unit. Wouldn't this approach work?

Absolutely not.
