RF has no air supremacy in Ukraine, so they have high loses, but they advance anyway. Small or large losses will not stop an empire, except Imperial Japan maybe.
Ukraines Air Force is tiny and poorly equipped. Compare it to just the Nordics for example who are soon on hundreds of F-35 and Gripen. Staging any mass movements against that kind of air support will be challenging.
Besides NATO already has a large land based army as well. US, Turkey, Poland , Finland all have large ground forces
