Coast Guard Boats are destroyers equiped with thicker hulls and more powerful engines. They are only seen once in Red Alert 2 Mission Sub-Divide of the Soviet Campaign. They are colored green on that mission. As RA2 is well known for its modding, some mods or maps feature it and can be built as a faster destroyer at the cost of some durability, contrasting the heavier hull that its design shows.
