Most of the personnel of the battalion-tactical group of invaders defeated near Mykolaiv are former Ukrainian military who switched to the Russian side in Crimea in 2014, the SBU has reported.

"Near Mykolaiv, the Ukrainian security forces defeated the battalion-tactical group of invaders. Most of its personnel are former Ukrainian military who betrayed our state in 2014 and switched to the side of the Russian Federation in Crimea," the SBU said in a message posted on the Telegram channel.

"Since then, the SBU has identified each traitor by name and has been waiting for an opportunity to punish them, as they were hiding in the temporarily occupied territory. Now Putin has helped the SBU bring the perpetrators to justice – he himself sent the traitors to certain death in Ukraine," the SBU said.

According to the Ukrainian intelligence service, the SBU also seized documents of the Russian military with callsign tables, mobile phone numbers, flash drives, SIM cards and personal documents of the invaders.
