retaining unit exp after retraining?

[Raz]

Did you not read what Thor the Bassist said? It cannot be done! He states it in the very first line!
And anyway, if I can remember, experience is tracked per individual soldier and the chevrons you see is the unit average. If you have half strength unit of 2 chevrons, and retrain them so they have a full strength, the average will be 1 chevron in the entire unit - Half will be 2 chevrons, the other half will be 0 chevrons.

But if you must you could also use:

create_unit "<location>" "<unit name>" <amount>,<chevrons>,<armour upg.>,<weapon upg.>

Which creates any unit you want. So if you want five 9chev hastati with gold armour and weapon upgrades spawned in Rome, you'd use this:

create_unit "Rome" "roman hastati" 5,9,3,3

if it can't be done through gameplay, I don't want it. especially what you are giving me is essentially to spawn a 9 exp unit. if I want to do that I would not have try to get an unit to max lvl through 100+ turns of battles. a simple one liner saying it is one of the hardcoded limits would have told me what I needed. that big post actually made me thought he didn't want to tell me how :(

As Raz said it is possible to create an experience 9 unit but you must keep re-training and re-training. When you wittle your troops down to the say 10 9 chevron troops and you retrain them they dont lose their experience but simply the group average goes down. You then send this unit into battle and next time they have experience 9 you will proberably have 17 or 18. Re-train then wittle down to about 25 now. Re-train, fight 30 left. Re-train, fight 34 left. Re-train fight 37 left...

This will go on until you have a reet good unit.
