This footage reportedly shows Russian troops using ground-based robotic systems and attack drones to carry out combat missions in Pokrovsk.

The Russian Ministry of Defence said on November 12 that units of the Radiation, Chemical and Biological Defence troops from the ‘Centre' group of forces were performing daily combat tasks and advancing in the Donetsk region of Ukraine.

Authorities said unmanned aerial vehicle crews were striking Ukrainian positions and manpower.

They added that operators of the ‘Courier' ground robotic systems were deploying aerosol smoke screens across designated areas to conceal troop movements.

The statement said the use of the latest drones enables the Radiation, Chemical and Biological Defence troops to conduct combat missions quickly and effectively.

Officials also noted that the Radiation, Chemical and Biological Defence troops mark the 107th anniversary of their founding on November 13.

The report also claimed that drone crews of the 6th Guards Tank Regiment of the 90th Guards Tank Division destroyed four Ukrainian armoured vehicles near Pokrovsk, as well as an American-made M109 self-propelled artillery unit.

Russia invaded Ukraine on February 24, 2022, in what the Kremlin is still calling a 'special military operation'.
