Comparing: (R) T-62A vs. 121B

Development of the first Soviet post-war medium tank started in 1951. In 1961, after developing and testing several working prototypes, the T-62A with a rifled gun and the T-62 with a smoothbore gun were deployed. In March 1962, mass production of the T-62A was discontinued. The T-62 tank was mass-produced from 1961 through 1975, with a total of twenty thousand vehicles manufactured. Later modifications of the vehicle are still in service.

The upgraded version of the 121 Chinese medium tank, developed in the 1960s. Unlike the prototype, the 121B was equipped with a modern 105-mm rifled gun, improved suspension, and reinforced front armor. The vehicles of this modification were equipped with infrared lamps and a laser rangefinder. The 121B aiming system had a higher firing accuracy than that of the Type 59.
