The "Solntsepek" systems were actively used by the warring parties during the conflict in Nagorno-Karabakh.
It is known that both the Azerbaijani army (18 launchers) and Armenian units (an unspecified number) had such weapons.

It is known that only one combat vehicle was destroyed during the fighting. This happened on October 9, when the drone was able to detect a single TOS-1A and point a high-precision munition at it, which fell into the launch package.
As a result, there was a powerful explosion, and then an involuntary launch of the rocket. Of course, the heavy flamethrower was disabled, although the crew, who were behind the armor with the hatches closed, had every chance to escape.

This incident is the first and only reliable fact of the loss of TOS during military operations, although before that they had to fight in Afghanistan, Chechnya, Iraq and Syria.
Azerbaijani "Suns" went through the entire war without losses, more competent use and a higher level of training of crews affected.
