Ukraine's Armed Drones Could Offset Some of Russia's Military Advantage

KYIV, Ukraine--Last October, as artillery shells fired by Moscow-backed separatists pounded a Ukrainian mechanized brigade, Kyiv responded with a powerful new weapon. A Turkish-made drone launched a missile and knocked out a Russian-supplied howitzer. This demonstration of force--the first drone strike in combat by Ukraine's military--unnerved Russia and fueled complaints from Moscow that North Atlantic Treaty Organization countries including Turkey, the U.S. and Britain were threatening Russia's security by supplying sophisticated new weapons to Kyiv.
