The TDA-3 () mobile smoke generator is a support unit that lays a covering smoke layer to obscure visual and thermal/infrared optics on the battlefield, obscuring advances of other units. This also blocks laser targeting. It is employed primarily by the Russian NBC forces to protect conventional units. History The first prototypes were delivered around 2016. Testing suggested that they could be very useful on the battlefield. Features The TDA-3 uses a modified Kamaz 5350 chassis with a 6x6 wheel formation. The cargo section of the truck contains three modules: An auxiliary power unit (APU), power unit, electrical appliances, and control panel. The APU consists of a TA-6A gas turbine that both powers all systems and projects the smoke onto the battlefield. Tanks for the smoke generator, one of 2500 liters and the other of 900 liters. A 2700-liter powder tank, acoustic mixer, mix pumps, and other equipment. Additional equipment, including meteorological equipment, spare parts, and emergency supplies, may be carried on a trailer or a separate vehicle. Once the APU activates, powder is fed into the exhaust to generate smoke, which rapidly disperses across the battlefield. The vehicle can begin issuing smoke as soon as 90 seconds after arrival. Enormous volumes can be generated by a single unit, with generation lasting between two and six hours, depending on settings. The unit can be refilled in the field. The ingredients for the smoke can vary. It can theoretically contain chemical components, and it has been demonstrated performing degassing, disinfection, decontamination, and pest control. Operations The TDA-3 was used in the Russo-Ukrainian War. At least one was lost around 23 February 2023. References Military vehicles introduced in the 2010s Military vehicles of Russia
