This Ukrainian intelligence officer was instrumental in kicking Russians out of northern Ukraine in 2022 and thwarting assassination attempts on Volodymyr Zelenskyy. Here is why he's optimistic about Ukraine's coming offensive.

Lessons learned from Russia's failed assault on Kyiv
Marchuk detailed how Ukraine gained experience in capitalizing on Russia’s logistical weaknesses, disrupting Russia-Belarus cooperation and on countering Russian sabotage techniques. These experiences will aid Ukraine’s forthcoming counter-offensive. Marchuk described how Ukraine deftly pushed Russian forces into Kyiv and in the process, overstretched their logistics. He recalled how “Russia’s long column of vehicles turned into a continuous traffic jam and was immobile,” and that soldiers in this column were given expired food. Budanov capitalized on its Russia’s immobile column by creating “special groups” of 30 people and 2-3 units with equipment, and it took only 20 of these groups to cause Russia’s logistics to collapse. Marchuk argues that the quality of training of the 72nd mechanized brigade was especially critical in strengthening these small groups.Battle of Kyiv: tactics and tricks that saved Ukrainian capitalUkraine’s operation to thwart the landing of Russian troops in Hostomel, an airfield 30 km to the north of Kyiv, was crucial to preventing the capital from being seized. Then, Ukraine’s National Guard and the first intelligence department destroyed not only a large number of helicopters and elite troops, but also prevented the landing of many Il transport airplanes carrying hundreds of paratroopers each. These were forced to land in Belarus and move on foot columns towards Bucha and Irpin. Marchuk also highlighted Budanov’s decision to flood dams instead of landing forces in Hostomel and its strikes on bridges near a major hydroelectric power station, which did not destroy the plant itself. To thwart Russian offensive operations that might accompany a Ukrainian counter-offensive, GUR could revive this playbook. To complement these deft military tactics, Ukraine also restricted Russia’s ability to leverage logistical support from Belarus. Marchuk described Belarus as a “weak link in Russia’s war effort,” as President Aliaksandr Lukashenka is trying to do everything possible not to enter the war, and Belarusian elites were willing to sabotage military orders. Marchuk believes that the sudden death of Belarusian Foreign Minister Vladimir Makei in November 2022 was interconnected with the events in Ukraine. With respect to combatting Russian sabotage operations, Marchuk recalled how Budanov “within hours” foiled a Russian plot to release prisoners from a pre-trial detention center in Kyiv “to pump the streets with criminals” and ensure chaos in the streets. The Wagner Group arrived in Kyiv after Russia’s prisoner release plot failed but it was unable to create terrorist attacks or assassinate Zelensky. Marchuk also praised the ability of the Ukrainian intelligence services to infiltrate into the Russian military, which prevented the assassination attempt on Zelenskyy as well as a Russian chain of terrorist attacks inside Kyiv. While Ukraine’s ability to sustain counter-offensives on multiple axes of advance and destroy Russia’s fortification infrastructure is unclear, there is considerable cause for optimism. As in-fighting sharpens between the Wagner Group and the Russian Ministry of Defense, Ukraine can leverage its unity and replicate its experience capitalizing on Russian logistical failures in Kyiv.
