Is it possible to upgrade my existing infantry, or must I disband the old units and build new ones?
I purchased the next military technology level which opened up Azab Infantry and made Yaya Infantry obsolete. It prompted me to choose the new unit type, but I cannot find a way to upgrade my existing infantry.
I'm in the middle of a Peasant War (endless uprisings) and have no manpower left. Will disbanding units put the remaining men back into the manpower pool?
