ukraine: Ukraine builds layered air defences as Russia ramps up strikes
Russia has unleashed regular long-distance missile and drone attacks since October, but it seriously increased strikes in May as Ukraine prepared for a counteroffensive this month. The strikes, which regularly kill civilians, look at least in part aimed at depleting air defence stocks so that fewer systems can be used to protect troops trying to advance under Russian air superiority, Kyiv officials say. "The most difficult is an attack by various types of aerial targets," said the Avenger unit's commander who goes by the call sign "Architect", his pre-war profession.
