KHARKIV REGION, Ukraine >> The four drones were designed to carry bombs, but instead the men of Ukraine’s Khartia brigade pack them with food, water and handwarmers and launch them in darkness toward the front line, a 15-minute flight away.

The unit commander who goes by the callsign Kit, or “cat,” pilots the tiny uncrewed aircraft from a basement room he jokingly calls their Airbnb. Guided by the drone’s night-vision camera, he drops the 10-kilogram (22-pound) packages one by one as close as he can to the position where as many as five infantrymen battle Russian forces in the late autumn chill. The delivery will hold them for two or three days.

That’s about as far as Kit dares look into the future. He knows that the reelection of Donald Trump will change something in his life, but as far as he and other Ukrainian soldiers on the front are concerned, trying to figure out how is a game for politicians. For him, all that matters is the distance he measures in the meters (yards) that Russian forces advance or retreat in the front-line sector that is his responsibility.

“We are trying with all our might to destroy them and win back our territories, so that it does not go any further, so that there are no more destroyed cities and destroyed lives,” Kit said. “We need to focus on the present in our work and try to do it effectively in the here and now.”

But he cannot escape the sense of a gathering storm.

Russia is increasingly hitting the Kharkiv region with unstoppable, building-leveling glide bombs and swarms of drones and chipping away at territory there. Its troops are advancing in the Donetsk and Zaporizhzhia regions. Up to 12,000 North Korean troops have been sent to Russia’s Kursk border region to help beat back Ukrainian forces there, according to U.S., South Korean and Ukrainian intelligence assessments.

Trump, who has called President Vladimir Putin “pretty smart” for invading Ukraine, has repeatedly criticized American backing of Ukraine. He characterized Ukrainian President Volodymyr Zelenskyy as “the greatest salesman on Earth” for winning U.S. aid.
