Anti-colonial hybrid defence: how Ukraine’s resistance fights in the occupied territories

Between 2022 and 2025 Ukraine’s resistance managed to inflict persistent losses and disruption on Russian forces in the occupied territories. The kinds of operation – from bombs and bullets to spies and sabotage as well as raids and ambushes – show a comprehensive guerrilla strategy aimed at eroding the occupier’s control. Ukrainian partisans first blunted the occupation through fear and attrition and later became an integral part of Ukraine’s broader hybrid defence strategy to reclaim its territory.

“Join the ranks of Atesh – we call on every conscious person who is ready to help us defeat the occupiers to join our ranks,” reads a leaflet from Ukraine’s partisan movement. The leaflet was not distributed in Crimea, where Atesh – meaning “Fire” in the Crimean Tatar language – originated. Nor was it distributed in Mariupol, Berdyansk, Donetsk or Luhansk, where Atesh’s partisans have struck and continue to strike.
