Makeshift roadblocks have been installed throughout this capital to impede the movements of Russian troops snaking toward the city in a convoy about 15 miles away.

On some strategic thruways, Ukrainians have parked trams and buses to restrict driving access. Checkpoints to inspect IDs have also been established to root out would-be saboteurs. “We have a lot of presents” for the Russians, Kyiv Mayor Vitali Klitschko said in an interview. “It’s not sweet. It’s very painful.”

“I call that 40-mile convoy, by the way, the biggest, fattest target in Ukraine,” retired Navy admiral James Stavridis, who previously led NATO forces as the supreme allied commander Europe, said on MSNBC. Put certain fighter jets “in the hands of the Ukrainians,” he added, “and watch that thing blow up.”

“More than likely, Russian forces have local air superiority, so it’s doubtful Ukrainian forces have a good opportunity to strike,” Michael Kofman, director of Russian studies at CNA and an expert on the Russian military said of Kyiv’s current posture. Given that imbalance, he added, “the Ukrainians’ best chance” of damaging the convoy at this point “is with drones.”

Ukraine has had some success striking Russian targets with Bayraktar TB2 drones, which were purchased from Turkey. Last week, Ukraine’s defense minister said in a Facebook post that additional Bayraktar drones had just arrived in the country, but it is unclear how many more drones Kyiv had bought.

Tony Radakin, the head of the United Kingdom’s armed forces, said during an interview with the BBC on Sunday that the Ukrainian attacks on the convoy are “impacting on morale” among Russian troops. Some of those troops are camping out in the nearby forest, Radakin added, for fear of staying in convoy vehicles that might be struck.
