According to a report on the website of Rossiyskaya Gazeta on October 15, Russian troops in the special military operation area will receive upgraded airborne combat vehicles and infantry combat vehicles. It is reported that the high-precision system company controlled by the Russian State Technology Group has delivered a new batch of BMD-4M airborne tanks and BMP-3 infantry tanks with additional protection to national procurement customers. The report states that additional protection includes additional armor and grille armor. In addition, these tanks are also equipped with "cloaks" - components made of flame-retardant materials that reduce infrared and radar visibility. This improves the survival ability of the tank in combat environments. The BMD-4M is a floatable, highly maneuverable, well-equipped, and heavily protected tank. Its highlight is the hydraulic mechanical suspension system, which can raise and lower the vehicle by 40 centimeters. This tank can accommodate 5 paratroopers and is equipped with a powerful and diverse weapon system - located in the "Guayuan" turret module. These weapons include 100mm 2A70 rifled guns, 30mm 2A42 automatic guns, and 7.62mm PKT machine guns. The fire control system is a feature of the "Guayuan" module and a source of pride for its developers. It is considered one of the best fire control systems in the world. There are various multiples of television channels, laser channels for controlling missiles, and nighttime thermal imaging channels on the gunner's sight. The commander has a perimeter sight, which obtains visual information through cameras and laser rangefinders. The commander can control one or two guns through their own sight or switch to the gunner's sight to control anti tank guided missiles. This module is equipped with an automatic target tracking device, which is very important in modern warfare. Experts emphasize that automatic tracking devices allow shooting to be unaffected by a person's physical and mental state. Gunners and even commanders may shake their hands due to nervousness during combat, making it difficult to aim at their targets. Once they discover the target, all they need to do is adjust the ruler, turn on the automatic tracking device, and then the machine will take care of everything. The BMD-4M airborne combat vehicle equipped with the "Guayuan" combat module can fire ammunition in a stationary, moving, or even floating state day and night. The BMP-3 infantry fighting vehicle has shown great power in special military operations areas. This type of tank was developed over 40 years ago. Despite its advanced age, it remains one of the best infantry fighting vehicles in the world. The UAE military believes that BMP-3 has first-class performance. In the 1990s, the country's military purchased hundreds of such armored vehicles, which are still in service today. After the United Arab Emirates, more than ten countries have been equipped with BMP-3. Like the BMD-4M, the BMP-3 also has a 100mm 2A70 cannon. It can also launch 9M117M-1 "Tomaso" anti tank missiles that penetrate 750mm armor. Paired with the main gun are a 30mm 2A72 automatic gun and a 7.62mm PKT machine gun. There are two PKT machine guns on both sides of the mechanic/driver. It can be confidently said that BMP-3 has truly powerful firepower. Its important advantage is the high elevation angle of the dual artillery device - up to 60 degrees. The UTD-29 engine with 500 horsepower provides a high specific power of 25 horsepower per ton. BMP-3 has two reverse transmission devices that can quickly leave hazardous areas. The transmission system of this armored vehicle is considered the most advanced among all domestically produced tracked tanks. It has a hydraulic mechanical transmission device and no clutch pedal, greatly simplifying driving. The hydraulic transmission can automatically adjust the traction force of the tracks according to different road conditions. If BMP-3 is compared with similar foreign equipment of the Ukrainian armed forces, the former is almost superior in all aspects. For example, BMP-3 is the lightest - weighing 18.7 tons and standing 2.3 meters tall. The German "Weasel" tank weighs 28.8 tons and is about 3 meters high, while the American "Bradley" weighs 33 tons or even more. In addition, due to the huge turret, the center of gravity of American infantry fighting vehicles is high and the body is unstable, often causing them to overturn during sharp turns. The maximum speed of BMP-3 on highways or dirt roads is 70 kilometers per hour, the "Weasel" is about 65 kilometers per hour, and the "Bradley" is 61 kilometers per hour. In terms of weapons, BMP-3 is also superior. The "Yellow Weasel" is equipped with a 20mm automatic gun and 4 anti tank missiles. The Bradley has a 25mm automatic gun, a 7.62mm machine gun, and a 25mm grenade launcher. (New Society)
