Ukraine Bolsters Air Defense with Arrival of Patriot Systems Amid Russian Aggression.

Patriot missile defense systems from the United States, Germany, and the Netherlands have arrived in Ukraine to help defend against Russian airstrikes. Ukrainian troops have been training on the systems in recent months and are almost ready to use them in battle. The delivery marks the end of Ukraine's lengthy effort to secure the defense systems, which were requested by the country's defense minister two years ago.
