Ukrainian footage reportedly shows the dropping of modified US-made 40mm projectile grenades onto a Russian T-80BVM tank. The effectiveness of the strike isn't clear. There is an initial flash of fire indicating some sort of propellent was rapidly combusted, but it's unclear if the tank suffered any structural damage. The vehicle continues to burn as the video ends, and as we've seen several times, Russian tanks are prone to catastrophic explosions if the on board ammunition storage catches fire.
