Ok as for the LTAR post, you guys don't need any more guns on your anti-aircraft vehicles...
So that wirbelwind is out 
Actually, the Wirbelwind would be less effective than the Ostwind unless you had a particularly good gunner, for a simple reason -- where the Ostwind has a feed tray for its ammunition (and the loader can just keep slapping sticks of 37mm rounds on the tray all day long), the Wirbelwind had separate 20-round magazines for each of its guns -- so that after you'd fired off your 80 rounds, you'd have to wait while the clips were changed before you could shoot again. Assuming that the clips were modelled, that would give you about a three-second burst, then you'd have to wait several seconds to reload.
If it was modelled as just one continuous ammo load, then it should be perked; the ROF would make it entirely too powerful as a 'free' ride.
