people say the ostwind was "rare" like it means something.
The 37mm Flak 43 on the ostwind is nothing special. The germans had a 37mm flak gun through out the war. The 37mm Flak 18 was was replaced by the 37mm Flak 36. The Flak 36 was the "standard version". The 37mm Flak 43 appeared only in limited number in the second half of the war. However, the round did not change with the models.
Whats was more "rare" is the chasis not the gun. All sides during world 2 had similiar anti aircraft guns. They were mounted on on all sorts of vehicle types.
Ofcourse in rl these guns were nowhere near as effective or as concentrated like you see in ah.
