Russian Air Force and Ukraine's Air Defense

The big challenge that they face since the beginning of the war both sides is the lack of air dominance. The Russian strike campaign is also draining Ukraine of air defense ammunition right you saw Russian military just reloaded another batch of Shahad drones from from Iran and that's a shot exchange that's very favorable to Russia. With Western help I think it'll happen but that's why I'm harping on the air defense issues and your term problem than now then the Russian Air Force can begin looking for ways to return itself to to the actual battlefield.
