Read previewUkraine's latest claimed strike on Crimea is likely another example of how its older, Western-supplied missiles can foil even Russia's most advanced air-defense systems.

"None of our missiles fired were intercepted by the enemy's 'highly effective' air defense," Ukraine's General Staff said.
