I finish my first official version of my naval mod who put the emphasis of using boat and amphibious for the main type of transportation to capture multiples objectives. The 2 sides who are fighting are the federation of Japan vs the American. Their goal, take the control of an illegal trafic that came under the radars of both nation.
