Avoiding Losses in a Losing Defense Battle
1. Disband all fleets
2. Do not harvest any more resources from warehouse
3. Spend as much resources as possible
*you can do so by constructing buildings/ships/research/donate to corps
4. This will leave the raider with minimal loot and zero Shootdowns
(Works when player is online/offline)
*If possible, use Truce Card and you will be protected for 12 hours
