The Ukrainians are better trained, theyre just having problems with the fact that the Russians are using unique technology like "mines" and "planes".

No, no, no. Air superiority is when your planes are more expensive. You see, the more pricey the plane the more superior the air. Missiles are cheap, and thus can't contribute to air superiority.
