It is based on the hull of the older Type 63 (which in turn is based on the Soviet PT76 amphibious light tank). The Type 63A features a number of improvements, in particular the new welded turret which features much greater armour protection and the 105mm main gun (capable of firing standard NATO projectiles as well as the gun launched anti-tank missile). The marines are believed to have continued operating the Type 63 and the non-amphibious Type 62 light tanks as secondary units. The Type 77 amphibious APC was the standard armoured transport for the marines for many decades. However, new designs have been adapted from the army to complement these aging transports. These include specially modified versions of the Type 89 and Type 63 APCs, with enhanced swimming capabilities. The Type 86 (or WZ501) IFV is also in service with the marines. Based on the Soviet BMP-1, it is armed with a single 73mm main gun and mounts an HJ73 ATGM (with max range of 3000 meters). For air defense, Chinese marines employ a mix of automatic and manually operated anti-aircraft artillery systems, as well as short range surface-to-air missiles. The marines have been seen operating the new Type 95 self-propelled air defense platform on an amphibious hull similar to the Type 77 APC. This platform is armed with four 25mm cannon with a short ranged SAM combination to achieve effective killing capabilities against low flying targets at short ranges. The Type 89 self-propelled 122mm gun is the first SP artillery system in service with the marines since 1999. This adds additional accurate firepower to the PLAMC.
