The T-90 is a Russian main battle tank, the so-called 3rd generation from modern times. The first prototypes of this vehicle were made at the turn of the 1980s and 1990s, and the car entered production in 1993. In the basic version (T-90), the combat weight of the tank reaches 46 tons. The drive is provided by a single diesel engine W-84MS with 840 hp. The primary armament is the 125mm 2A46M smoothbore cannon, and the secondary armament consists of the 7.62mm PKMT machine gun and the 12.7mm Kord machine gun. In 2016, the unit price of the T-90MS was estimated at approximately USD 4.6 million.
The T-90 tank is in fact a very far-reaching modernization of the T-72B, also using many components from the T-80U. Originally, during the USSR, it was assumed that the T-90 (originally designated as T-72BU) would replace the T-64, T-72 and T-80 vehicles, leading to the unification and unification of the armored weapons of the Soviet Army. Currently, along with the T-14 Armata, it is the most modern tank in the service of the armed forces of the Russian Federation. Undoubtedly, the latest versions of this vehicle (T-90M and T-90MS) are modern combat vehicles, which, however - probably - are inferior to Western designs, especially in the field of electronics or armor. It is worth adding that these types of vehicles were used in combat, inter alia, during the civil war in Syria since 2011 and during the fighting in the Donbas (since 2014).
The first work on the self-propelled rocket artillery system TOS-1 began in the mid-1970s at the arms plant in Omsk. In 1988, the set was adopted by the Soviet Army. To this day (2017), it remains in service with the armed forces of the Russian Federation. Serial production started in 1988 or 1989 and continues to this day in Omsk. The TOS-1 set is based on the chassis of the T-72 or T-90 tank. On such a chassis was mounted a 24-guide or 30-guide 220mm rocket launcher for the TOS-1 family of missiles. They are thermobaric missiles, i.e. they have fuel-air warheads. For this reason, the TOS-1 set is called in Russia the "heavy flamethrower". The main purpose of the TOS-1 is to support its own armored forces during breakthroughs, fighting in built-up or mountainous terrain. In the course of combat, the TOS-1 is most often used to cover own tanks or - less frequently - mechanized infantry. TOS-1 underwent its baptism of fire in Afghanistan in 1988-1989 (Operation Typhoon), where it proved to be excellent. It was also used in combat during the Second Chechen War, and only then, during the fighting for Komsomolskoye in 2000, the world learned about the existence of such weapons in the Russian arsenal. A small number of TOS-1 sets are currently part of the armed forces of only a few countries, including Azerbaijan, Armenia, Iraq or Kazakhstan, but most of all the Russian Federation.
