Kyiv: Russia's full-scale invasion of Ukraine has killed hundreds of thousands of people. It has also served as a proving ground for new weapons systems and raised an uncomfortable question for the North Atlantic Treaty Organization: Is the alliance prepared for the next war it might have to fight?
Five Ukrainian and Western defense officials told Reuters that developments on the battlefield are moving so quickly that some NATO weapons and tactics risk becoming outdated. While Ukraine - which is not an alliance member - adapts in weeks, NATO buys and develops systems over years, sometimes decades.
