Fighter jets are necessary to cover tanks in an assault. If the tanks are about to break through Russian lines, I'm sure Russia would commit every aircraft it has to stop the attack. The Battle of Kursk during World War II is known as one of the greatest tank battles in history, but it was also one of the greatest air battles.

Instead of a "fighter jet coalition", it would be better for Ukraine to have just one type of fighter. It would be simpler to train on and maintain. Since the US is reluctant to supply ATACMS, it should supply GLSDB.

That would be great. Russia should not be informed until a week before the fighter planes are deployed in Ukraine.

The West must supply Ukraine with a fighter plane ASAP so training can start. Tanks aren't enough. They must be part of what is called combined arms operation. Fighters will provide air cover as tanks and infantry move forward.
