Let's be honest here, everyone wants to see this added. Generals 1 (with the expansion) was really cool and fun, but it was missing a "Battleship" factor. Land-to-sea or Sea-to-Land battles would, in my opinion, be a great addition to Generals 2. Quite certain I'm not the only one that would like to see Navy action.
Here are some pictures of the Iranian Navy to make a GLA Navy force believable, and armed with suicide boats of course.
