Watch for where the Submarine is firing from. If you are controlling the ship wait until the Submarine fires then click on Attack Ground right where you think the ship fired from.

Battleships vs Catapults
Most people use Attack rather than Attack Ground when using Catapults. Use this to your advantage. Keep your ship moving toward a Catapult until it fires, The after it fires, wait a second then attack the Catapult. By moving toward the Catapult as it fires, the Catapult will fire over the ship, missing it. After firing, the enemy will most likely run, if they run, you run as well waiting until the Catapult moves within range again. If they move closer, which most Catapult users do, turn your ship around and charge them. Keep moving forward again, until they fire then click on attack the Catapult.

Lock ("We got lock baby!")
When you right click attack on an enemy unit with a Destroyer, it will follow them and kill them unless something kills the Destroyer or it gets lost. This is really useful when attacking Transports with Destroyers. Just get a right click on the Transport, fire and forget. Quite often the Transport commander will devote a lot of time trying to get away from the Destroyer which unless other Ships get involved, is pretty hard to do. Land locks are often not as effective as water locks because there are many obstacles players can use to hide behind to confuse the enemy.

Got a lock on you?
If you have a Transport with a Destroyer or two locked on, forget about that Transport, it's dead. head to the nearest shore, enemy or not, and unload quick! If you can Blizzard, or set up a trap, lead the Transport and the Destroyers on it back into the track.

If you have an enemy locked onto your Peon or Peasant, build a Farm, then cancel it. This will break the lock. If the enemy isn't paying attention they will find their unit has stopped following the Peon.

The best way to to kill a Transport is to get a lock on it with a Destroyer.

There are server options available for unloading troops from a Transport. After a ship has left shore, select the Transport and hit U for unload then select where you want your Transport to unload.

If you have a specific unit you want unloaded, select the Transport then click on the portrait of the unit you wish to unload.

Loading units can be more difficult, select a unit then right click on the Transport. The Transport will move to pick up the last unit commanded to enter the Transport. If the Transport has difficulty reaching the shore or unit in question it will sometimes stop. Be sure to check the progress of the Transport, moving it to the proper location if necessary. When unloading and loading units at the same time, make sure the unit unloading from the Transport is quickly moved out of the way as it often blocks units trying to board the Transport.
