Historical Reference:
In the second half of the 1950s, the USSR was developing tanks without a turret. In Kharkov, they worked on a vehicle called “Product “Bush”, conceptually similar to the Swedish Strv 103. The gun guidance was supposed to be only vertical or with minimal horizontal angles. The project did not advance beyond the model stage.
