The first recorded videos of the Russian TOS-1A multiple launch rocket systems (MLRS) firing at Ukrainian targets have surfaced online, showing the devastation and destruction it is capable of on the frontlines.

News of Russia using thermobaric weapons isn’t new. Russia had used thermobaric weapons before in Chechnya in 1999 and during the Russian intervention in Syria, where al-Assad forces used vacuum bombs made by Russia.

Russia was reported to have deployed the TOS-1A Thermobaric MRLS (also known as the “Solntsepyok” or “Sunshine”) in March, where it was spotted on the back of a lorry en route to the frontlines in Belgorod around late February.

Russia first admitted its use of the devastating weapon last March in Ukraine. At the same time, the Ukrainian government accused Russia of using vacuum bombs and cluster bombs in war. Amnesty International and the British Ministry of Defense have since confirmed the use of cluster bombs and thermobaric weapons, respectively, with SOFREP also reporting on the matter last April.
