The 9K11 Malyutka is an anti-tank guided missile system that was developed in the early 1960s by the Soviet Union. It was designed to be a man-portable guided weapon that would be a more capable follow-up for the 3M6 Shmel AT-1 Snapper. The 9K11 is also known by its NATO reporting name of AT-3 Sagger. This weapon system remains in widespread use today as it is a cost-efficient and simple to use modern anti-tank guided weapon.

This anti-tank system is a wire-guided missile with a fairly simple design. The HEAT warhead is located at the front end with an impact fuse. Most of the body is taken up by a solid propellant rocket motor. Its two exhaust nozzles are fitted due to the fact that the wire and control section for the four foldable wings are located at the end. The original and older models of the 9K11 used MCLOS guidance, but later models featured the more effective SACLOS guidance system; these were only used on helicopters and vehicles. This guided weapons system is mainly used from the manpack launch installation and from various vehicles, including the BMP-1 and BMD-1 mechanized infantry combat vehicles, as well as various tank destroyers based on the BRDM-1 and BRDM-2. The 9K11 Malyutka may also be launched from several export versions of the Mi-24 and Mi-8 combat helicopters. Effective against most Cold War-era tanks, the latest versions of the 9K11 have been drastically improved compared to its predecessors.

Considered one of the most iconic Soviet weapon systems, the 9K11 Malyutka was produced in large quantities and used widely throughout the Cold War. It was not only used by the Soviet Union and Warsaw Pact nations, but also widely exported across the globe.
