Description
The AT-4 HEAT is a low trajectory, low-dispersion weapon and each preloaded shell carries an extremely effective shaped charge. And to ensure stability and accuracy the shell is equipped with highly effective stable fins that unfold as the start of trajectory. The AT-4 rocket launcher is manufactured by a Swedish Company.
 
Variants :
AT-4 HEAT: basic version
AT-4CS HP: CS for Confined Space and HP for High Penetration warhead
AT-4CS AST: CS for Confined Space and AST for Anti-Structure Tandem
 
Technical Data
 
Operation
The AT4 took many of its design features from the Carl Gustav, which operates on the principle of a recoilless weapon, where the forward inertia of the projectile is balanced by the mass of propellant gases ejecting from the rear of the barrel. To fire, the gunner first removes the safety pin located at the rear of the tube, which unblocks the firing rod. He then takes a firing position ensuring that no one is present in the back blast area. If firing from the prone position (lying on his stomach) he must also place his legs well to the side to avoid burning himself. Then the gunner moves back the front and rear sight covers, allowing the sights to pop up into their firing positions. The AT4 requires little training and is quite simple to use, making it suitable for general issue. However, as the cost of each launcher makes regular live-fire training very expensive, practice versions exist which are identical in operation but fire reloadable 9mm or 20mm tracer ammunition.
Sight
The AT4 sights are iron sights and are similar in concept and use to those on assault rifles. The AT4 can mount an optical night sight on a removable fixture. In U.S. military use, the launcher can be fitted with the AN/PAQ-4C, AN/PEQ-2, or the AN/PAS-13 night sights.
Projectiles

HEAT (High Explosive Anti Tank)
The AT4 HEAT can penetrate up to 420 mm (16.5 inches) of RHA with beyond-armour effect.[18]
AT8 (Bunker Busting)
A version of the AT4 where the standard HEAT projectile is replaced with the bunker busting warhead developed for the SMAW.

Combat use
The AT-4 HEAT has an effective range of 300 m and carries a warhead with unmatchable behind armour effect. it is this combination that gives the AT-4 HEAT its ability to penetrate the armour of modern light armoured vehicles and devastate their interiors.
