A drone recording reportedly from recent fighting in the Bakhmut area of Donetsk shows a Russian TOS-1 Thermobaric "Heavy Flamethrower" rocket barrage striking Ukrainian positions.

The TOS-1 220mm 30-barrel multiple rocket launcher systems (MLRS) is mounted on a T-72 tank chassis, and due to its short range, doesn't fall under an artillery designation, but instead rolls at the front of the assault with tanks and infantry. It launches "thermobaric" warheads, also know as fuel-air bombs or vacuum bombs, which combust the oxygen around the target, resulting in a powerful fiery explosion.
