Any number of units can move across an army boundary, but you must place a "Done" marker on each of them to remind you that they can't move again in the same turn. Starting on the next turn, the unit(s) can be activated by the new army's command chit.
The way this is worded in the Galicia scenario is confusing. You're really activating an army's zone, not the units of that army specifically. The Ypres scenario instructions make this more clear.
