The MATADOR ("man-portable, anti-tank, anti-door") is a man-portable, disposable anti-armour and anti-brickwall weapon system developed by Germany, Israel and Singapore. It is an updated version of the German-Singaporean 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. The MATADOR was developed jointly by the Singapore Armed Forces (SAF) and the Defence Science and Technology Agency (DSTA), in collaboration with Rafael Advanced Defense Systems and Dynamit Nobel Defence (DND) joint team. Capabilities The MATADOR is among the lightest in its class. The warhead is effective against both vehicle armour and brick walls. The weapon has little back-blast, making it safe for operation in confined spaces. The MATADOR is supposed to be capable of defeating the armour of most known armoured personnel carriers and light tanks in the world. The dual-capability warhead, when acting in the delay mode, creates an opening greater than in diameter in a double brick wall, and acts as an anti-personnel weapon against those behind the wall, offering an unconventional means of entry when fighting in built-up areas. The MATADOR's projectile is claimed to be insensitive to wind due to its propulsion system, which results in a highly accurate weapon system. Warhead The warhead can be used in both high-explosive anti-tank (HEAT) and high explosive squash head (HESH) modes against armour, walls, or other fortifications respectively. Modes are selected by adjusting a probe (most likely a fuse extender): extending it for HEAT mode and leaving it retracted for HESH mode. Counter-mass system Similar to the Armbrust, the counter-mass counteracts the recoil of the weapon upon firing. The counter-mass consists of shredded plastic, which is launched out of the rear of the weapon when it is fired. This plastic is rapidly slowed by air resistance, allowing the weapon to be fired safely within an enclosed space. In addition, the positioning of the counter-mass takes into consideration the centre of gravity of the weapon to ensure good balance for better accuracy. Variants Variants of the original HEAT/HESH (HH) weapon have been developed by Rafael and Dynamit Nobel Defence, designed primarily for anti-structure use by soldiers operating in dense urban environments.
