Advance Wars 1+2: Mission 9 (Olaf's Navy with Max)

I rarely bother with this map, since I don't like the premise. If you would prefer, you could bring Andy instead, but it is probably faster with Max if you know where all of the enemy units are.

Basically, Olaf has a giant navy that will instantly sink yours. Then exploiting how bad the naval units are in the game, you walk around the land, taking the north bridge to bypass all of them and seize the HQ for the win. If you ask me, this map perfectly encapsulates why the naval units need a massive buff in the series and why Tiny Metal never bothered to make any naval units.
