The AT-4 is a man-portable, disposable, single-use anti-tank weapon, developed by FFV (now SAAB-Bofors) in Sweden. The name of the weapon is a play on its 84 mm bore (AT-4 is pronounced as "Eighty-Four"), as well an indication of its role (AT for "anti-tank"). It was and remains one of the world's premier expendable infantry anti-tank weapons. It is also distinct from most other weapons in its class, being a recoilless gun rather than a rocket launcher, though many sources still mistakenly identify it as the latter. The AT-4 is also often assumed to simply be a disposable version of the Carl Gustav M2, but the only major attribute their ammunition shares is the same bore.

All AT4 weapons are single shot and fully disposable. You simply aim, fire, destroy the target and discard the empty tube. Furthermore, the AT4 family has proven itself to be a highly reliable, robust and durable weapon system that has been extensively proven in combat. Its key characteristics include high target effect and hit probability – creating a high target kill probability for each fired weapon.

The AT4 is an 84-mm unguided, portable, single-shot recoilless smoothbore weapon built in Sweden by Saab Bofors Dynamics. Saab has had considerable sales success with the AT4, making it one of the most common light ant-tank weapons in the world. 

The AT4 is intended to give infantry units a means to destroy or disable armoured vehicles and fortifications,although it is generally ineffective against current modern main battle tanks (MBT).The launcher and projectile are manufactured pre-packed and issued as a single unit of ammunition.

The AT-4's gun tube is long and cylindrical, with numerous external fixtures. The muzzle is surrounded by a thick composite bracket, which in turn is enveloped by an octagonal shock absorber; the venturi is flared, conical, and has an octagonal shock absorber rim as well, though its visibly broader than the muzzle. Numerous brackets are wrapped around the tube, making quick identification by counting them relatively pointless. The shoulder pad on the aft underside has a broad salient shape, and includes a folding wire-frame shoulder rest with a short canvas strap; when extended, the shoulder rest takes-on a delta shape. A long tube covered by a conformal housing (which contains a cable used to fire the weapon) runs from the trigger mechanism to the breech along the top of the tube. The front and rear sights are located on the forward upper right side of the tube, underneath rectangular protective covers which can be slid-away when the sights needs to be raised. A rectangular foregrip is located just behind the muzzle on the underside of the weapon, and is folded against the tube when not in use (some AT-4s were produced without a foregrip). The firing mechanism, safety catch, and cocking lever are on top of the tube in its midsection, just behind the rear sight cover. The AT-4 is usually fitted with a sling, the swivels for which are located on the lower left side between the sight covers, and on the very bottom of the tube just in front of the venturi. Various stencilings and instructional decals are plastered onto the tube. AT-4s may be painted in different colors or camouflage patterns, but are usually solid olive drab in color.
   The construction of the AT-4's gun tube is extremely similar to that of most modern disposable anti-tank rocket launchers, but is still able to cope with the overpressure of an 84 mm recoilless round. The tube consists of reinforced fiberglass, with numerous sheet steel and composite brackets. Unlike the Miniman, the bore liner is not metallic, although the venturi is made of aluminum. The shock absorbers on the AT-4 are made of a hard foam rubber material. The sights, trigger mechanisms, and shoulder rest frame are made of steel, while the sight covers, foregrip, and numerous other fixtures are made of plastic. The projectile itself has an aluminum shell, and the fins are probably made of aluminum as well. The AT-4 is rated for operating temperatures of −40 to +60 °C.

   The iron sights consist of a front post and a rear peephole, with the range adjustable for 100 m to 500 m, in 50 m increments. Two different peepholes are available for the AT-4; a 2 mm hole for use in broad daylight, and a 7 mm peephole for use at night and in order low-visibility situations. Interestingly similar set of sights are also used on the M141 BDM anti-structure rocket launcher, probably due to a similar range and trajectory. A variety of optics may also be fitted to the AT-4 by clipping them on, to include night vision optics, infrared optics, and laser aiming devices.
   The main body of the projectile is shaped like a generic artillery shell, with a cylindrical body, a finely-tapered conical nose, and a boattail. It has a diameter of 84 mm, a length of 462 mm, and a fin span of 290 mm. The trailing body consists of a metal shaft, enveloped by a spring-loaded assembly containing 6 stabilizer fins that spring into a hexagonal pattern when the projectile leaves the tube. The main body of the projectile is marked with a yellow band, for easy identification of UXO, should the projectile fail to launch and/or detonate properly. The projectile is fired down a smooth bore, and is stabilized solely by drag via its fins when in flight, as it does not rotate. Although the AT-4 is frequently referred-to as a "rocket launcher", the projectile does not contain a rocket motor.

The AT-4 projectile weighs 1.81 kg, and contains 453 g of Octol that force a thin copper charge liner into a jet-like penetrator upon detonation. This charge will penetrate up to 400 mm of RHAe at a 0-degree obliquity, but there is more to the lethality of the warhead than just its penetration. The AT-4 was the first anti-tank munition especially designed to employ enhanced lethality against armored vehicles, through what the manufacturer has termed "Beyond Armor Effects". Using a number of special attributes built into the warhead, the damage caused to the interior of a penetrated armored vehicle and its occupants are dramatically increased, resulting in a significantly greater probability of disabling an armored vehicle. These effects include an instantaneous overpressure of 1 bar above normal (twice the ambient air pressure of the Earth's atmosphere at sea level), greatly increased back-spalling and penetrator spatter, a flash of light over 100 times stronger than sunlight, greatly increased smoke from combustion of the warhead and armor during penetration, and more intense heat than that of a generic shaped charge of similar penetration. Exactly what components of the AT-4's warhead create the Beyond Armor Effects are still highly classified (though observers have noted that it probably has something to do with the charge liner's unusual trumpet-like shape, a focus ring around the front of the liner, or an additional layer of a special aluminum-based alloy bonded to the back of the liner), but as video footage and photographs of AT-4s hitting armored vehicles graphically demonstrate, they are not a marketing overstatement.

The AT-4 may be fired from a standing, sitting, kneeling, or prone position, though prone firings are typically forbidden during training. When firing from a prone position, the user must lie at a 45-degree angle off the axis of fire, as being exposed to the backblast at the venturi will result in severe injuries.
   To fire the AT-4, the user must first remove the safety pin at the rear of the launch tube, ensure no personnel are in the backblast area, and shoulder the weapon. If the iron sights are to be used, the user must slide the cover for the front sight rearward, slide the cover for the rear sight forward, and flip-up the sights. The cocking lever must then be flipped moved forward, upward, then to the right, then take aim at the target. When the target is in the user's sights, the safety lever must then be held down, and the trigger button pressed-down by the user's thumb; if the cocking lever is not set to the armed position and the safety lever held-down with the trigger is pressed, the trigger will not engage and fire the weapon. The user must also *squeeze* the trigger until it "breaks" (like the trigger on a typical rifle) rather than simply jabbing it, as doing the latter could throw-off the aimpoint. The weapon will then fire, and the tube is discarded; it isn't designed to withstand the stresses of multiple firings, and thus cannot be reloaded.
