TOS-1A "Solncepek" is a further development of TOS-1 Buratino. As it's forerunner it launches a deadly barrage of smoke incendiary or thermobaric missiles. It has less launchtubes than Buratino, but less weight and hence higher speed. Also it's more armoured and capable to carry additional ERA kit "Relict" exactly like MBTs, which makes Solncepek more durable.
