Regarding adding the elements of land combat vehicles to China's tech tree during the Cold War

Currently, the Cold War section of China’s tech tree still lacks some subsequent upgraded models, For example, the Type 92B wheeled infantry fighting vehicle and the Type 86A infantry fighting vehicle, which were upgraded and put into service after 2000, both come equipped with a stabilized version of the common turret featuring a 30mm main gun. Additionally, the Type 92B wheeled infantry fighting vehicle is also armed with the Hongjian-73Type anti-tank missile。And in the future, a series of infantry fighting vehicles equipped with 8-round 90mm cannons, as well as wheeled and tracked 122mm self-propelled howitzers, can still be added,
