The announcement came from National Police Chief Ihor Klymenko, who was appointed the country's acting interior minister following the death of government officials in a January 18 helicopter crash on a foggy morning in a residential suburb of Kyiv. Klymenko said in a press release Thursday that Ukraine is forming "Offensive Guard" assault brigades that will be made up of police and border guards and have the goal of "liberating our territories."

"These are people who went through the crucible of 2014-2015, some of whom fought already in 2022," Klymenko said. "Some of them are wounded. The units will consist exclusively of volunteers who are driven by patriotism, and there are a lot of such people in our country."

Ukrainian President Volodymyr Zelensky has said that withdrawal of Russian troops from all territories, including Crimea, is essential to ending the war, which is approaching its one-year anniversary. He has vowed to take back the peninsula, saying during a televised address on August 29, 2022, that Ukraine's military has "kept the goal" of recapturing Crimea since it was annexed.
