The Roman Underwater Warfare Command tasks 30 Type-III U-boats to cut all supplies entering the Empire Of Yamakami's islands in the Atlantic (ships are allowed to leave), the U-boats are advised to move at no more than 3.5 Knots while in hostile waters. these boats are supplemented by patrols of F.W. 19's (50 tasked to the Area, groups of two) which where designed for the roll of harassing small ships, any cargo vessel attempting to enter will be given three warnings and 5 minutes to turn around, before the aircraft uses its Gau-8 and 102 mm gun to obliterate it. U-Boats only give one warning and three minutes to any ship, U-Boats will pick up any surving crew if they do sink a ship.

(Islands dont last long without food, or oil)
