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 call sign 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 22-pound packages 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 President-elect Donald Trump’s win in the U.S. will change something in his life, but as far as he and other Ukrainian soldiers on the front are concerned, figuring out how is a game for politicians. For him, all that matters is the distance that Russian forces advance or retreat in the sector that’s 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.

Zelenskyy was among the first world leaders to publicly congratulate Trump and said the two discussed how to end “Russian aggression against Ukraine” when they met in September.

The Biden administration has said it will send as much aid as possible between now and Trump’s Jan. 20 inauguration to help Ukraine hold back Russian forces and maintain a strong hand in potential peace negotiations. But Russia is pressing just as hard for an advantage in what most believe are crucial weeks to come.

Aviator, a Khartia soldier launching the supply drones, said he can only do his job and hope for the best.

“You feel you’re useful, that you are in the right place, that the lives and health of our brothers depend on your work,” said Aviator, who returned to Ukraine from a job in Poland to join the army. “We’re just doing our job, we don’t have time to worry about the election.”
