The AT-7 Saxhorn is the NATO reporting name for the 9K115 Metis ("mongrel") man-portable SACLOS (Semi-Automatic Command to Line of Sight) wire-guided anti-tank missile system of the Soviet Union.


The missile is fired from the 9P151 launching post - which has a simple tripod for support. It can also be fired from the shoulder.

The launching post weighs 10.2kg. The missile is launched from the tube by a booster rather than the gas generator used on the AT-4 Spigot system.

The 9S816 guidance system is powered by a thermal battery attached to the launch tube shortly before launch - the missile itself is remotely powered along the guidance wires.

The missile can be launched from an enclosed space such as a building or cave but requires at least 6 meters behind the launcher, and a total internal volume of at least 100 m³. The missile has a short minimum range of 40 meters, and can engage targets moving at up to 60 km/h.

The missiles warhead is a single HEAT shaped charge.
