MATADOR (Man-portable Anti-Tank, Anti-DOoR) is a 90-millimetre (3.5 in) man-portable, disposable anti-armor weapon system developed in collaboration between Israel and Singapore. It is an updated version of the German Armbrust design, and operates on the same principles. The development of this weapon began in 2000 and the MATADOR will eventually replace the German-Singaporean Armbrust Light Anti-tank Weapon, which has been in service since the 1980s.
