-- This plan is to send a limited amount of force to try to initially push the attacker off a planet.
-- It should only be invoked if the defender can spare some units and still have a strong base defense.
-- This is to provide a middle ground between the all out rush (when the AI decides that it has overwhelming
-- force) and the total defensive posture (when AI doesn't clearly have overwhelming force).
