Russians are using something called Glider Bombs that can be fired from distance from airplanes without being exactly above the targets. Ukrainians are unable to shot those plane with ordinary air-defenses. They need F-16’s + air superiority to shoot down those planes firing from distance. But these will start coming in significant numbers only in the second half of this year. Ukraine might be facing the most difficult part of the war this year. So I am part of those who think that Emmanuel Macron might simply be right about sending troops (If necessary) to Ukraine. Actually, this year there is a real possibility for the entire Ukrainian front to collapse. No matter how much aid the EU is still providing.
