MOSCOW, March 14. /TASS/. Russia’s Battlegroup Center has broken down rotation of Ukrainian troops in the Avdeyevka area with the use of Grad multiple launch rocket systems, the Russian defense ministry told TASS.

"Having received the coordinates of the place of deployment of Ukrainian troops, artillerymen took an unprepared firing position. After a trial launch of 12mm projectiles, the combat vehicle commander, in cooperation with the team of a reconnaissance unmanned aerial vehicle, adjusted the gunsight and fired the rest of unguided projectiles at the designated target. According to data recorders, rotation of Ukrainian troops was frustrated, with Ukrainian forces sustaining serious losses while retreating in the Avdeyevka area," the ministry said.
