SKOLE, UKRAINE - FEBRUARY 19 : Vadim Kirov, 49 years old, co-founder with his wife Zoryana Hankova, 51 years-old, of the Haidamatska Sich, explain to the 11 teenagers how to hold a weapon on February 19, 2022 in Skole, Ukraine. Across Ukraine, civilians are participating in such groups to receive basic combat, medical and survival training. While Ukrainian officials have acknowledged the country has little chance to fend off a full Russian invasion, Russian occupation troops would likely face a deep-rooted, decentralized and prolonged insurgency. Russia has amassed tens of thousands of troops on its border to Ukraine. (Photo by Gaelle Girbes/Getty Images)
