BJ-2 12 series off-road vehicles adopt detachable soft tops, which are mainly used for commanders' riding and weapons carrying platforms. The car is suspended by front and rear hard bridges and steel plates, with short wheelbase, high ground clearance and quite strong off-road capability. The brake and clutch pedal of the vehicle are suspended, and the clutch and brake master cylinder fixed on the bulkhead of the engine room are pushed by the push rod. Suspension and girder are relatively strong. Vehicles can also be converted into 75 105mm recoilless gun vehicles, 63 multi-barrel rocket launchers and "Red Arrow" 73 anti-tank missile launchers, with strong combat capability.

However, BJ-2 12 also exposed the problem of poor comfort during use. Since 1980s, on the basis of introducing, digesting and absorbing foreign advanced technologies, Beijing Automobile Factory has upgraded BJ-2 12 by more than 0/00 technologies, and launched BJ-2 12L, BJ-2020N, BJ-2020s and BJ-200. Starting from BJ-2020, the engine power was increased from 75 horsepower to 85 horsepower, and radial tires were used for the first time in China, which solved the side slip problem. The three-speed front-speed transmission was replaced by a four-speed transmission, and the metal hardtop appeared for the first time.

BJ-2 12 and its subsequent models are frequent visitors to the National Day military parade. 1984, BJ-2 12 Party and state leaders inspected Tiananmen Square. 1999, BJ-2020 reappeared in Tiananmen Square as a platform for people to carry vehicles, weapons tractors and various equipment.

In 2008, China's second-generation light off-road vehicle "Warrior" rolled off the assembly line, and BJ-2 12 gradually faded out of the historical stage.
