Sole Harbor is the fourth, War Room-exclusive stage available in Advance Wars and Advance Wars 2: Black Hole Rising. The stage takes the shape of a giant peninsula, upon which one of the two headquarters is located, the other of which is situated upon the mainland. Just by looking at the map, it is obvious that the army located on the peninsula has a grand, immediate advantage over the forces based on the mainland; by comparison, there are many more territories under the control of the peninsula-bound army. However, that is not the only difference between this stage and that of its predecessors, as this map is the first to incorporate Ports and Shoals as a part of its landscape, as well. Ports enable armies to engage in sea-faring warfare, providing Template:Aws, Cruisers, and Template:Aws to aid in such battling, and the Shoals allow for Landers to dock and accept the loading of units scheduled to be delivered to a specific location quickly and easily via the sea. Either way, the most battle-intensive area of this map will be the land bridge that connects the mainland to the peninsula, especially since there are only three Ports and that is the single, unclaimed land segment that exists between the two headquarters. The version of Sole Harbor available in Advance Wars 2: Black Hole Rising is identical to the one seen in Advance Wars.
