Between 1980–1990, the Royal Thai Army purchased a large amount of surplus and recently retired military equipment from the United States to serve as a deterrent against communist neighbours. One such procurement was the M163 VADS SPAA system, of which 24 were ordered in 1981. Due to the obsolescence of the M163 in its intended role, it was primarily used as a fire support and anti-infantry weapon. In 2015, the RTA ordered a modernisation package from the Israeli company IMI for the M163, resulting in the M163 TVADS.

The Thai M163 was introduced in Update "Tusk Force" as part of the Japanese ground forces tree. The Thai M163 is completely identical to the one found in the US tech tree. While not as capable, nor able to reach out to the same distance as larger systems, the M163 does benefit from the very high rate of fire of its Vulcan armament. Due to these limitations, M163 players may find themselves driving rather close to the front lines to provide protection to allies and engage approaching aircraft, so extra care must be taken not to overextend. However, when the M163 unleashes its stream of 20 mm tracers towards a target, it can prove an intimidating sight to the enemy.
