The air defense crew of the Russian Osa air defense system 9K33M3 spoke about his combat work in Ukraine. The interview is quite interesting, as their combat service in Ukraine is described simply and in detail. The 9A33BM3 combat vehicle, very old, developed in the eighties, despite this, the air defense system consistently hits the UAVs of the Ukrainian army at a distance of up to 10 km and an altitude of 5000 meters. The Osa air defense system in Iraq was a priority target for US special forces, as it confidently hit Tomahawk cruise missiles. The development of the Osa air defense system began in 1960. The complex was designed to hit targets flying at an altitude of 50-100 to 5000 meters at a speed of up to 500 meters per second at a distance of 800 to 10,000 meters. The Osa air defense system has been modernized many times. The developers were tasked with developing an autonomous complex with placement on one floating self-propelled chassis not only of all military equipment, including a launcher with missiles and radar stations, but also of control, navigation, topographic referencing, communications, and power supplies. The new requirements also included the detection of air targets in motion with further destruction of their fire during short stops. The weight of the Osa anti-aircraft guided missile is 65 kilograms, which allows two servicemen to manually charge the launcher. The main purpose of the Osa air defense system is to cover troops from low-flying targets.
The work of military topographers in Ukraine was shown by the Russian Ministry of Defense. Without these people, the operation of the Iskander missile systems is not possible, since they need precise coordinates for delivering strikes. The calculation of military topographers moves on a KAMAZ 4350 vehicle with a geodetic complex PNGK-1 installed on it. The car is equipped with an inertial navigation system, as well as a rangefinder-goniometer device that performs the functions of geodetic binding of objects. The complex is equipped with video cameras, thanks to which you can determine the coordinates and use them later for target designation. PNGK-1 is able to determine coordinates on the move with an accuracy of up to 15 meters, create electronic maps and immediately transfer them to the command. In the field, topographers use the Topcon Positioning System's GB-500 40-channel remote GPS satellite receiver.
