The MAT-120 cargo mortar projectile, designed and manufactured by Instalaza SA, is fired from 120 mm smoothbore mortars and carries 21 submunitions up to a range of 5,500 to 6,800 m, according to the mortar barrel length.The MAT-120 incorporates an electronic safety and arming system. When stored, the MAT-120 round does not contain any electrical energy. The main fuze generates all necessary power after firing, once the projectile is in flight.Each submunition has its own electronic super-quick impact fuze. The fuze controls activation after submunition scattering, initiation of the submunition warhead on impact, self-destruct after 20 seconds, or self-neutralisation after a few minutes.The safety and arming system ensures safety while storing, handling, firing and while in flight, reliability of the submunitions on impact and a safe target zone some minutes after firing.MAT-120 submunitions have a dual function:anti-armour, penetrating up to 150 mm of Rolled Homogenous Armour (RHA)anti-personnel (about 650 fragments with a 18 m effective radius).The MAT-120 projectile is fired in the same manner as any other conventional mortar round and does not require any specific training. After firing and once the preset time in the fuze has functioned, the round spreads the submunitions to fall freely in a near-vertical trajectory, reaching the target in a random pattern covering a circle some 50 to 60 m in diameter. The hit probability on a target with the dimensions of a main battle tank within the target area is close to 20 per cent. The effective area of each submunition overlaps
