I was going to get to that. The vehicles exist, but will not spawn naturally on a map because there are no spawners. the only way to get them in a vanilla map is to use the debug executable to spawn the tank/plane. Before you ask, the debugger is here;
http://www.shacknews.com/file/4460/batt ... executable the download link at the top is an ad, use the one at the bottom of the page.
I can give you an edited map to you, would be no trouble at all.
to spawn a vehicle, press the magic ~, and type, "Game.spawnObject (Objectname)" without the quotes, and in (Objectname), put the ammo count. no, I'm kidding, the object name. The name of objects can be found in the Objects RFA in Objects.con files. in this case, it is "AC-130" and "KingTiger" without the quotes. Press enter to key it in. Only the debugger can spawn objects like that.
