Armourer buildings

[The spartan]

How do you get these buildings to work? That is, I have a master armourer and I can not retrain any units to upgrade their armor value and any new units I make in that city do not have any additional armor either. Any thoughts?

That's because your unit has already maxed out in its armor level.

For example,
http://m2tw.warlore.org/units/Quapukulu - the Qapukulu can upgrade to +1 armor because it has level 1 (default), and level 2 (upgrade at level 5 armorer)
http://m2tw.warlore.org/units/Gothic_Knights - the Gothic Knight cannot upgrade armor at all because it only has level 1 (the default level).

Units that can upgrade to +3 armor include dismounted byzantine lancer, and Catholic spear militia.

If you move a unit into a place that has some kind of armourer in it, and right-click on the unit, if an armour upgrade is possible it will say so - it will say "next armour upgrade heavy mail" or something like that. Then right-click on the armourer building to see what level of armour it produces. If it says "light mail" then you can't upgrade that unit until you upgrade the armourer. If it says "partial plate" then you will be able to do upgrades to heavy mail and partial plate (you don't have to do it twice though, you always get the highest upgrade possible in one go). Many of the lighter units will not say anything about an armour upgrade as they are not allowed any armour upgrades. Note that with some upgrades of this nature (eg the Swordsmith) you must not reload the game before the next turn after paying for the upgrade otherwise you pay for the upgrade but it doesn't happen next turn (it has been forgotten, it's a bug).
