? Please just open YouTube and watch videos. Also in our clan real tank drivers from the army said you see the shot fired. It is not realistic that the tank shot is invisible.
It dont need to be "tracer" i think, perhaps head signature you see as a gunner. It was good as it was, now with the patch its gone.
Lets play "realistic" tank sims like STEEL BEASTS PRO Pe. You will see the same there.
