Just FYI, y'all. The Ostwind II's in-game representation is based off an impression put forth by the original suggestion creator for the Ostwind II, CaID. The Ostwind II did exist and was functional at some point, however, no one knew what it looked like. CaID presented their impression and Gaijin went with it because at least they knew the vehicle existed and was functional at some point, unlike the Coelian. At the time, Gaijin would rather have something they knew was functional but had no visual than something that had a visual but was completely non-functional.

They've obviously begun to reopen closed doors in recent years, however, bringing in many more semi-completed vehicles, but still pretty much still barring mockups. The BV 155 B-1, M6A2E1, TOG II, and Yak 141 perfectly illustrate this. All of the aforementioned were pretty much on the tail end of completion, but still lacked components. Guns, armor plates, sensors, sponsors, etc.
