The electronic warfare system of the TOS-1A Solntsepek heavy flamethrower systems has been upgraded.
This improved electronic warfare system gives it a protective dome from enemy drones, a gunner-operator of the combat vehicle told Russian media.
"The electronic warfare system helps us. It includes anti-drone guns and other systems that jam and suppress communications," he said.
Electronic warfare helps protect the vehicle and crew by blocking signals on various frequencies used by FPV and other drones, making the flamethrower systems less vulnerable to air attacks.
