>Blood in the Water<

You start in Vladivostok. Your first priority is to secure the Ore Node to the north of your starting position. Build some Defences there to protect it. Start churning out Naginatas and Shokaku Battle Fortresses. Once you have a decent force, head north and destroy the Soviet Naval Yard.

Next, move south and bombard the Soviet Defences from the south. Don't rush in; soften them up from a safe distance.

After dealing with the southern defences, secure the Ore Node in the southwest corner of the map. Build a Dojo and a Mecha Bay in this new location. Use this as your secondary base to finish off any remaining Soviet forces and capture their Ore Nodes.

Now for the big guns: the Giga Fortresses are available! Three of these behemoths have been sent to help you. Send them to the docks and annihilate Oleg's Naval Yards. The Giga Fortresses on the water can easily handle any enemy ships.

When you're ready to take on Oleg's land bases, transform your Giga Fortresses into Sky mode. Use them to eliminate Oleg's three bases. Oleg will blame Moskvin for this mess.

Keep an eye on the clock. After some time, Giles' troops will arrive from the southeast corner. Your Giga Fortresses should be more than capable of driving them off. Once Giles retreats, refocus on the Soviets.

For defense, use any regular Naval units you have to protect your Structures. Continue producing Giga Fortresses from your main base.

To support your Giga Fortresses, produce Jet Tengus to provide air cover. These will help clear the skies while your Giga Fortresses demolish everything in their path. Once Oleg's bases are destroyed, it's time to deal with Moskvin.

Head over to Moskvin's purple base, located in the northeast part of the map. He'll have a lot of units, but surprisingly, not much Anti-Air. Use your Giga Fortresses and Jet Tengus to easily destroy his Structures and Units. With Moskvin defeated, the mission is complete!
