Okie - as for retraining, thats answered about 20x in other threads - plz search the archive cuz its alot of typing and I am a lazy bum.

Now - disbanding units. There are a couple of reasons one would do this - first if you have a unit (specifically - a general) that loses a couple of battles and survives - and thus is at rank -2. This means that his army has a -1 to their honor. Ditch the tactical numbskull by disbanding his unit.

The other reason is when, in the midgame, you have inferior troops (ashi's usually) that are sucking up maintenance when harvest comes around. You can disband these units to make sure you have enough koku to retrain/train and build the quality troops and buildings you need. Its also useful in late game situations when you have groups of troops sitting around deep in your empire that you don't need - disband em and save money.

Qapla!
