The AT-4 is a modern 84 mm anti-tank grenade launcher manufactured in Sweden. The first copies of this weapon appeared in the early 1980s, but the weapon entered service in 1987 and remains in it today. The weapon is 102 cm long, with a grenade launcher weighing only 6.7 kilograms. The effective range of the shot is up to 300 meters, with a maximum range of about 2,000 meters. The projectile fired from this weapon has an initial velocity of 290 m / s. AT-4 was developed by Swedish plants Förenade Fabriksverken, which are now part of Saab-Bofors Dynamics. In essence, it is a far-reaching development of the 74 mm Pansarskott m / 68 grenade launcher, which entered service with the Swedish army in the 1960s. Like its predecessor, it was designed as a light anti-tank weapon of infantry subunits, capable of engaging Soviet light and medium armored vehicles at any point in their armor, and Main Battle Tanks against the side and rear parts of their armor. The weapon turned out to be successful and entered service mainly with the US Army, which replaced the M72 LAW grenade launcher.
