Okay, add a little more content, because I don't know which topic these pictures should be placed under.

As you can see, the content in the picture comes from the Helicopter Expo a few days ago.
The Army Aviation Corps showcased the main models of helicopters they are currently using. The "Mi-171 Armed Helicopter" does not seem to be a weapon testing platform, but unfortunately, our information is very limited, and only a small amount can be learned from those military enthusiasts who pretend to be mysterious.
