This is normal; the rules of attacking outside the base, whether on (Occupation Site, Resources field, Battle Lab or Nuclear Silo), your units will be killed, not injured, so if you lose a battle, you will lose all your units even if the Service Center is empty. And if you win a battle but have some loss, the result will be the same.
Why are there no damaged units and just killed units in Resource Zones, Battle Lab, or Nuclear Silo?
