Missile 9K115-1 Metis-M (AT-13 Saxhorn-2)

The 9K115-1 Metis-M (NATO reporting name AT-13 Saxhorn-2) is a Russian portable anti-tank guided missile system developed as a successor to the 9K115 Metis family to augment company-level motorized units. Russia formalized the introduction of an upgraded variant, the Metis-M1, which entered service in March 2016.

The Metis-M is a man-portable system operated by a three-man crew carrying a launcher and five missiles. The system can be fired from prone positions, standing foxholes, combat vehicles, or rested against local structures for shoulder firing. Missile guidance is semi-automatic over a wire link. The missile design excludes gyroscopic coordinators, electronic units, and onboard batteries, placing guidance processing off the missile. System components comprise the 9M131 missile (and 9M131M and 9M131F ATGMs for the Metis-M1), 9P151 and 9P151M launchers, and the 1PN86BVI thermal sight. The Metis-M1 target set includes main battle tanks equipped with Explosive Reactive Armor and Active Protection Systems, light armored vehicles, and fortifications in all weather conditions day or night.

The system is deployed by ground and airborne units in Russia and has been exported to several countries, including South Korea, Algeria, Bangladesh, Syria, Egypt, and Iraq. It is also operated by various non-state entities, including Hezbollah, the Free Syrian Army, and the Houthis. South Korea acquired Metis-M systems from Russia as debt payment. Following test firings between 2009 and 2011 in which ten of seventeen missiles either missed or failed to detonate, South Korea temporarily withdrew the system from active service before follow-up testing prompted its reintroduction.

Hezbollah used the Metis-M during the 2006 Lebanon War against Israeli Merkava tanks. During the Syrian Civil War, anti-government forces used the system against armor, infantry fighting vehicles, trucks, firing posts, and a derelict MiG-23MS aircraft. These systems originated from captured Syrian Army stocks as well as foreign transfers, including six sets supplied by Bulgaria via the United States. FUNCINPEC forces also used the system during the 1997 Cambodian coup.
