bulletproof vest. The Type 19 uniform with new xingkong digital camouflage patterns, tactical vest, backpack, protective gear, and eyewear started to replace Type 07 uniform series since 2019. Along with the uniform, a new communication system, personal computer, tactical interface, and assault rifle family QBZ-191, new variants of the QSZ-92 pistol family, along with whole new sets of weapon systems are also being adopted by the PLAGF since 2019. These new upgrades are components of the new Integrated Soldier Combat System, a program aiming to overhaul the PLA's infantry equipment. Transformation In 1987 the PLA ground forces, which relied upon obsolescent but serviceable equipment, were most anxious to improve defenses against armored vehicles and aircraft. Most equipments was produced from Soviet designs of the 1950s, but weapons were being incrementally upgraded, some with Western technology. One example of upgraded, Soviet-design equipment was the Type 69 MBT, an improved version of the Type 59 MBT, itself based on the Soviet T-54. The Type 69 had improved armor, a gun stabilizer, a fire control system including a laser rangefinder, infrared searchlights, and a 105 mm smooth-bore gun. In 1987 the existence of a new, Type 80 MBT was revealed in the Western press. The tank had a new chassis, a 105 mm gun, and a fire control system. The PLA was believed to have atomic demolition munitions, and there were unconfirmed reports that it also had tactical nuclear weapons. In any case, nuclear bombs and missiles in the Chinese inventory could be used in a theater role. The PLA had a scarcity of antitank guided missiles, tactical surface-to-air missiles, and electronics to improve communications, fire control, and sensors. China began production of the Soviet Sagger antitank missile in 1979 but lacked a more powerful, longer range, semiautomatic antitank guided missile. The PLA required a mobile surface-to-air missile and an infantry shoulder-fired missile for use against helicopters and certain other aircraft. The PLA Ground Forces continue to undergo significant modernization and re-structuring to deal with potential threats and enhance their capabilities. Front line troops such as special forces, marines and paratroopers are given priority in receiving modern weapon systems and equipment. Other areas of improvement are its battlefield C4ISR capabilities, with the introduction of satellite communications, wireless networks, and digital radios, army commanders are now able to maintain constant communications with their front-line units while on the move.
