Captured Russian inmates who have been sent to the front lines in Ukraine as part of the Wagner Group, an infamous mercenary organization with ties to the Kremlin, say they've witnessed public executions of deserters and disobedient troops, per a new report from Polygon Media and the independent Mozhem Obyasnit outlet."Those who disobey are eliminated — and it's done publicly," Yevgeny Novikov, a former inmate who was recruited by the mercenary group said, according to a translation of the report from the Daily Beast.Alexander Drozdov, another former inmate cited in the report, said many of the Russian prisoners sent to the front line in Ukraine by Wagner are drug addicts and "completely insane."While some recruited prisoners may desert or disobey orders, others "are just fucked up and bulldoze their way through," Drozdov said, noting that these fighters "are very different from ordinary mercenaries."The first batch of prisoners to survive six months of fighting in Ukraine was recently released back into Russia, with the head of the mercenary group celebrating them as heroes deserving of great respect while also advising them not to drink too much, do drugs, rape women, or kill."
