AT4

AT4 is Saab’s family of disposable shoulder-launched weapons, widely used as a compact infantry anti-armor and assault system. Its design philosophy is different from guided anti-tank missiles: AT4 trades long-range guidance for simplicity, portability, and rapid issue to infantry units. That makes it especially relevant for force structures that need many lightweight weapons rather than a smaller number of complex launchers.

Saab presents AT4 as a versatile family rather than a single fixed round, with variants tailored for armor, structures, confined spaces, and other battlefield targets. The system’s value comes from matching warhead effects to common infantry problems: light armor, fortified positions, field works, and urban obstacles. Because it is disposable, training, logistics, and stockpile depth are central to its real-world effectiveness.

AT4 matters because it gives small units immediate direct-fire punch without the cost and support burden of guided missiles. In modern conflicts, such weapons are often used not only against vehicles but also against buildings, firing points, and barriers. For HiWars readers, AT4 should be positioned as a practical infantry tool whose battlefield impact comes from availability and ease of use as much as from penetration figures.
