Mass desertions and illnesses resulting in fatal outcomes have hit Ukraine’s 151st Separate Mechanized Brigade following fighting in the Kharkov Region. A representative of Russian security services told RIA Novosti about the deteriorating situation within the Ukrainian unit.

Several months ago, the brigade was withdrawn to Chuguyev to replenish its ranks after suffering losses during Operation Medvezhy Ugol (Bear’s Corner), carried out by Russia’s Northern Group of Forces in the Kharkov Region.

However, the unit encountered further problems after arriving at its designated recovery location. According to the Russian security source, large numbers of Ukrainian soldiers abandoned their posts without authorization. Many troops also suffered from diseases contracted while serving on combat positions, with numerous cases ending in death.

Operation Medvezhy Ugol concluded in October. According to the Russian Defense Ministry, Russian forces captured 28 settlements and secured control of 461 square kilometers of territory during the offensive. The ministry also reported that 1,810 Ukrainian soldiers were killed in the operation.

On October 16, Colonel General Evgeny Nikiforov, commander of Russia’s Northern Group of Forces, informed Russian President Vladimir Putin that the operation had been completed.
