Base is designed to prevent 2 and 3 stars. Center and peripheral buildings are separated by a gap to prevent drags and hogs from heading to the center. Drags will go around the base destroying peripheral buildings while being hit by air defense and die. Hogs will go around the base destroying peripheral defense until they go BOOM on double giant bombs. High hit point storages are placed close by air defense so drags will get shot down while attacking them. But storages are not close enough to lead drags to center.
