Development/Description Following development of the X1 light tank, essentially a modernised M3A1 Stuart light tank, Bernardini rebuilt to a new standard two vehicles known as the X1A1. The Brazilian Army did not adopt this model but development continued and resulted in the X1A2 which is similar to the X1A1 but is based on a new chassis instead of a rebuilt M3A1 Stuart. Between 1979 and 1983 50 X1A2s (military designation MB-2) were built for the Brazilian Army. A version with an automatic transmission was proposed, called the X1A3, but this did not reach the prototype stage.


Description The hull of the X1A2 is all-welded steel with the driver's compartment at the front, fighting compartment in the centre and the engine at the rear. The driver is seated at the front of the hull on the left and is provided with a single piece hatch cover that opens to the left. Mounted in front of the hatch cover are three periscopes for observation when the hatch is closed. The all-welded steel turret is in the centre of the hull with the commander, who also acts as the loader, on the left and the gunner on the right. Both are provided with a single piece hatch that opens to the rear. The commander's cupola has five observation periscopes and the gunner has three and a telescope linked to the main armament. The vertical volute suspension has three bogies each side with two road wheels each, with the drive sprocket at the front, idler at the rear and three track-return rollers. Optional equipment includes a laser rangefinder for the main armament, full range of night vision equipment and an air-conditioning system. Prototype X1A2s had a French D921 gun as fitted to the Panhard AML-90 (4 × 4) armoured car and early production ENGESA (6 × 6) Cascavel armoured cars, but production vehicles have a 90 mm Cockerill gun made in Brazil by ENGESA which is also now fitted to current production Cascavel armoured cars. A 7.62 mm machine gun is mounted coaxially with the main armament and a 12.7 mm machine gun is mounted externally at the commander's position for anti-aircraft use. Three electrically operated smoke dischargers are mounted either side of the turret at the
