M136 AT4 The M136 AT4 is the army's primary anti-tank weapon. The M136 AT4 is a rifle used primarily by infantry forces to defeat and defeat small arms. The gun's rugged design allows for precise delivery of the warhead against the 84mm high-explosive weapon. The M136 AT4 is a lightweight, self-propelled, unarmed, free-flying, fin-stabilized, rocket-style cartridge, expendable, one-piece, fiberglass-wrapped weapon. The M136 AT4 is portable and only fires from the right shoulder. The launcher is waterproof for easy transport and storage. Unlike the M72 Act series, the M136 AT4's trigger does not need to be extended before firing. Although the M136 AT4 is used in limited visibility, the firefighter must be able to see and identify the target and estimate its distance. After the first field of the weapon, a reusable night vision mask was developed and put into service. This allows the use of standard night vision equipment. The system has a tactical engagement range of 250 meters and has been used in numerous combat situations. Ammunition is in a disposable delivery tube. The system weighs 15 pounds and can be used effectively with minimal training. Technical data

The M136 AT4 warhead provides excellent penetration and post-weapon lethality. Extremely destructive, the 440 gram shaped charge explosive penetrates over 14 inches (35.6 cm) of armor. (1) Consequences. The nasal cone sags; the impact sensor activates the fuse. 2) Extinction. A piezoelectric fuse element activates an electric detonator. Start the main charge and the booster explodes. 3) Log in. The main charge fires and enters a gas jet that penetrates the armor plate. (4) Aftermath of weapons.

Swedish 84 mm (3.31 in) unguided, manned, disposable, shoulder-firing anti-tank weapon, manufactured by Saab Bofors Dynamics (formerly Bofors Anti-Armor Systems and formerly FFV Ordnance).
The AT4 is not considered a missile launcher because the warhead is not powered by a rocket engine; In the same way, it is not a precision rifle, but rather a recoilless rifle because the trigger is smooth and not a rifle.

Saab achieved great commercial success with the AT4, making it one of the most widely used anti-tank weapons in the world.
The name AT4 is a play on the weapon's 84mm caliber, (84) "eighty-four" being a homophone of "A-T-4".
The name also doubles as an alpha-phonetic word for weapons, thanks to the common military abbreviation "AT" for "anti-tank".
This name was coined for export purposes, as the nickname "eighty-four" was a common Gliese nickname for Carl Gustaf after the 8.4 cm caliber pistol.
Antitank Guided Missile
The AT4 is intended to provide infantry units with the ability to destroy or disable armored vehicles and fortifications, although the vulnerable parts of the tank's armor are not applicable to current main battle tanks (MBTs), in especially armored jets. The launcher and projectile are pre-assembled and released as a single weapon unit, and the launcher is discarded after a single use.
(Miniman) Adopted by the Swedish Army in the late 1960s. Like the M/68, the AT4 was designed by Förad Fabrikswerk (FFV) and manufactured at its facilities in Zakrisdal, Karlstad, Sweden.
The FFV began research in 1976 on a replacement for the m/68, developing a counterproductive individual anti-tank weapon that could not overcome the heavy armor protection of the MBTs (main battle tanks) on the frontal turrets. The AT4 is designed to arm light armored vehicles in any direction, MBTs from the sides or rear, and as a weapon against buildings and fortifications. The FFV was also a design goal for the weapon to be simple to use, rugged, and far more accurate against moving targets than previous weapons. Another key requirement is that the AT4 not only penetrate armor, but also have an unarmored damage effect after penetration. The FFV and the Swedish Army began the first evaluation firing of the AT4 prototype in the spring of 1981 with 100 trials in early 1981.
Before the AT4 was adopted by Sweden, it competed for the US Army's new anti-tank weapon mandated by Congress in 1982, and the FGR-17 Viper failed to replace the law. M72. Six weapons were tested by the US Army in 1983: the British Law 80, the German Armbrust, the French APILAS, the Norwegian M72E4 (an updated M72 Law), the US Viper (for comparison purposes base) and the Swedish AT4. The U.S. Army informed Congress in November 1983 that the AT4 FFV came closest to meeting all major requirements for an Act M72 replacement.

Although impressed with the simplicity and durability of the tested version of the AT4, the US military saw some room for improvement, particularly the addition of rear and front bumpers to the missile tube, and changes to sights and trim. After these changes, the AT4 was adopted by the United States Army as the M136 light general-purpose weapon.
The Swedish military also recognized these improvements and adopted an Americanized version of the AT4 as the Pansarskott m/86 (Pskott m/86), adding a forward folding arm to stabilize the AT4 during aiming and shooting. The advance is the only difference between the AT4 adopted by Sweden and the US Army version.
Due to the urban combat environment regularly encountered by U.S. military forces during the Iraq War, the U.S. Army Close Combat Systems Manager is responsible for obtaining overhead orders for the standard version of the AT4 and the US Army now commands the AT4. CS version (limited space).

The AT4 can be considered a disposable and inexpensive alternative to the Carl Gustaf 8.4cm recoilless rifle. The AT4 carried over many of its design features from Carl Gustaf, which operates on the principle of a barrelless weapon, where the forward momentum of the projectile is balanced by the momentum of the propellants exiting the barrel . But unlike Carl Gustaf, who used a heavier and wider steel tube with his weapon,
The disposable AT4 design dramatically reduces manufacturing costs by using a smooth fiber reinforced outer tube. Having a disposable gun makes for easier and cheaper construction. In a single-use pistol, the barrel must contain a single pressurized jet, which can be thrown out if destroyed or burned, unlike traditional pistols. survive the failure of most pressurized jets, so they must be ruggedly constructed and made with heat resistant materials. The pressure is also kept very low compared to most traditional guns. Its light, thin barrel and low pressure, combined with almost complete elimination, allow the use of relatively large projectiles (compared to mortar and artillery systems), which would not be possible with a manned weapon.
The system, originally developed by FFV for Carl Gustaf, features a plastic carriage mounted behind the center.
