THOM ("Tandem HEAT Optically guided Missile") is a Lindian anti-tank guided missile with a tandem-charge high explosive anti-tank warhead. It was developed by Pittacus, a Lindian weapon system designer and manufacturer. The THOM missile platform can be operated by a team of infantry, as well as be launched from ground vehicles, ships and helicopters.

While earlier versions were dependent on optical guidance instructions from the user, newer versions of the missile (THOM-III and higher) have fire and forget guidance systems as well as the ability to follow a lofted trajectory in order to perform top attacks. Earlier, shorter ranged, versions of the THOM platform sent guidance instructions over a fibre optic cable. While modern shorter ranged variants still retain this feature, the long range variant (THOM-IV) receives its instructions over a RF link.
