In the 1950s, the Soviet Central Auto and Tractor Directorate began a development program to replace the AT-P series of artillery tractors (which were based on the ASU-57 airborne self-propelled gun) with a new generation of vehicles. The MT-L was developed to meet this requirement based on the PT-76 amphibious light tank chassis. The MT-LB is the armored variant of the MT-L. Entering production in the early 1970s, it was cheap to build, being based on many existing components, e.g. the engine, which was originally developed for trucks. It is built at the Kharkiv Tractor Plant^[2] and under license in Poland by Huta Stalowa Wola^[3] and Bulgaria.^[4][5]

The crew, a driver and a commander/gunner sit in a compartment at the front of the vehicle, with the engine behind them. A compartment at the rear enables up to 11 infantry to be carried or a cargo of up to 2,000 kg. A load of 6,500 kg can be towed. The vehicle is fully amphibious, being propelled by its tracks in the water.^{[citation needed]}

A small turret at the front of the vehicle fits a 7.62 mm PKT machine gun with 360-degree manual traverse and an elevation of −5 to +30 degrees. The vehicle is lightly armored against small arms and shell splinters with a thickness of 3 to 10 mm of steel with a maximum of 14 mm for the turret front.^[6] The infantry compartment has two hatches over the top, which open forwards. There are four firing ports—one on either side of the hull, the other two in the rear twin doors of the infantry compartment.^{[citation needed]}

The driver is provided with a TVN-2 infra-red periscope, which in combination with the OU-3GK infra-red/white light searchlight provides a range of about 40 m. All vehicles include a CBRN defense system.^{[citation needed]}

IraqEdit

• MT-LBV fitted with wider tracks.
• MT-LB converted into a SPAAG by mounting a ZU-23-2 23×152mm twin anti-aircraft gun on the rear part of the vehicle. The gun had its wheels removed and as such cannot be easily dismounted and used separately. There were at least two variations of this conversion; one with the ZU-23-2 mounted in an open-topped turret, the other with the ZU-23-2 mounted on a platform extending beyond the hull of the MT-LB with a roof for the gun operators. The second version was most likely intended to be used in a fire support role, as the roof would hinder the gun's sights at high elevation.^[13]
