About 100,000 Russian troops are believed to be on the border with Ukraine. While countries like the U.S. and U.K. have sent military hardware to Ukraine, Germany has been conspicuously reluctant to send equipment.

The offer of helmets, made on Wednesday, has been derided by some Ukraine officials. For one, Kyiv’s mayor Vitali Klitschko dismissed the offer as “a joke” and said it had left him “speechless.”

“The behaviour of the German government leaves me speechless. The defence ministry apparently hasn’t realized that we are confronted with perfectly equipped Russian forces that can start another invasion of Ukraine at any time,” he told the Bild newspaper on Wednesday.

“What kind of support will Germany send next?” he asked. “Pillows?”
