Ukrainian President Volodymyr Zelensky confirmed in a Telegram post on Tuesday that the country's forces had used the Army Tactical Missile Systems (ATACMS) in their fight against the Russian military.
"Today, [I'm sending] special thanks to the United States. Our agreements with [US] President [Joe] Biden are being fulfilled. ATACMS have proven themselves," Zelensky stated.
The long-range missiles struck nine Russian helicopters in the eastern part of Ukraine.
