Read previewRussia has been hitting Ukraine with glide bombs, with one official reporting that Moscow's forces dropped 700 of the devastating explosives in just under a week.
Shooting down the fighter-bombers means putting precious air defenses closer to the front, where they'll be at greater risk.
Ukrainian air defenses also don't have enough ammo.
Glide bombs began showing up last year but have seen increasing use since the start of this year.
Russia has a variety of glide bombs in its arsenal, including some weighing more than 6,000 pounds.
