As in the title, why certain tank’s gunner sight shake so much after shot but in few others don’t ? I am pretty sure most modern MBT Fire Control Systems are fully stabilized so it shouldn’t shake and obscure view as much. More like smoke and dust could but no gun revoil. All M1 Abrams 120mm shake so much that I fell uncomfortable and make me think I am gonna miss ( it really does xD). Same as T-80U f.e. In the other hand on Leopards/Challengers/Type 90 it doesn’t shake at all
At some point you will not gonna even notice the shake.
