“After some young guys began laying down their arms and going over to the Lugansk [militia] side, a group of about 10 people arrived from the centre. Our commander, Colonel Meshynchuk, said they would provide psychological support. In reality, this group served as a blocking detachment. During each battle, they would watch us to make sure that nobody abandoned their positions. They fired without warning on anyone deemed suspicious”, Yankovsky said.
The commander of the blocking unit was a Right Sector fighter named Vuyko going by the nom de guerre "Punisher", according to the officer. His aides included a fighter from Ukraine’s Nikolaev region, a Georgian national, whom Yankovsky suspected was a mercenary, and a sniper with the alias "Raven" who would “take up a position in the rear during battle and threaten to kill anyone who runs in the wrong direction”.
