I don't know - there were several effective land armies in WW2 - Germany, US, UK (though small), Russia from 1942 or so. They didn't have it much easier then. There was technology then, which was simpler but also more raw. What they did have was good officers, NCOs and training. I don't see reason to believe that a side in the Ukraine war has these.
