For anyone trying to do level 9 on hard mode: I managed to win by only making battlecruisers and submarines. Use your infantry to capture as many structures as possible, while covering with your other units. Only build battlecruisers at first. All you land troops will eventually die, but it does not matter. Once the AI starts build a lot of boats, start making some submarines to defend your battlecruisers. Once you have the enemy under control, start moving up the map.
