This order enables you to upgrade part or all of a single subformation of a unit to be upgraded to a different subformation. (There is also a mass upgrade option available in the OOB/Supply statistics screen in AT Gold)

To do such an upgrade the subformation must comply to the following:

* Have enough supply in a selected higher HQ to pay for the supply consumption cost of the upgrade. May be overseas HQ, but max 2 HQs up the chain of command. Must be within rulevar 53 AP range of hex were upgrading is taking place. This supply usage is not subject to AS dammage.

* Have enough XP that might be required for the upgrade
