Armor stats override?

[maty743]

I'm wanting to somehow override the armor stats of the unit trees I've created. For the correct visuals some units have top tier armor and some have low tier, so I want to be able to define a set value for each unit to keep balance correct.

I've seen this done in the Custom Troops mod for Crusader Blade (my troop trees are for that as well), where you could override stats, hp and shield hp as well. So I'm wondering if anyone can guide me on how to pull this off myself?

Any help or tips would be very much appreciated.

Thanks!
