Syria has fired TOS-1A Solntsepyok thermobaric rocket launchers and Grad multiple rocket launchers against the Islamic State positions.
The Syrian Army published a video of firing of the rocket launchers last week. The Solntsepyok is a Soviet 220mm 30-barrel multiple rocket launcher and thermobaric weapon mounted on a T-72 tank chassis. TOS-1 was designed for defeating enemy personnel in fortifications, in open country, and in lightly armoured vehicles and transport.
The launch vehicle is equipped with a fire control system with a ballistic computer, aiming sight and 1D14 laser range finder. The other standard equipment consists of a TKN-3A sight for the commander, a GPK-59 navigation system, an R-163-50U radio station, an R-174 intercom and a 902G smoke grenade launcher with four barrels.
