The main difference between the TOS-1A "Solntsepyok" heavy flamethrower system (produced at the Omsk Transport Machine-Building Plant) and artillery guns is their operating principle. Artillery usually strikes ground targets, while the TOS strikes closed enemy positions (bunkers, pillboxes, and fortified firing positions). This was stated by a serviceman of the Russian Armed Forces.
The TOS crew consists of three people: the commander, the gunner, and the driver-mechanic. We fire thermobaric projectiles with a range of up to 6 kilometers.
According to him, fire adjustment is carried out using drones. Usually, the TOS crew strikes, firing up to 6 projectiles, after which it leaves the position.
The principle is this: when a projectile explodes, a wave with increased pressure is created. It passes into the room through the cracks and strikes the enemy with excessive pressure. We inflict significant damage.
Earlier, Defense Minister Sergei Shoigu inspected the production of the TOS-1A "Solntsepyok" at a plant in the Omsk region. He was informed that the production of guns in 2023 increased by 2.5 times due to scaling production and increasing staff. The plant in Omsk operates around the clock.
