Just to avoid confusion, Alman is correctly pointing out that in a Retreat phase, any units of inactive countries will be destroyed (that is the auto-destroy this thread is discussing). But it will not be done in the move phase - the only time a unit is destroyed in the move phase and removed immediately is if the unit has no adjacent empty territories to which it could be ordered.
