Now I have been patient for long enough. Guys, a tanker'S joy can be acchieved so easily:
Tatarataaa...
Get SBP, and you're done - quality sim experience assured.
...rattattataaaaa....
So, now I feel relieved. Sometimes a man must say what a man has to say!
Edit:
P.S. If you disable gunner's primary sights for all tanks, AI and players must use the secondaries, which are purely optical and in principle the same like in WWII. Use T72 and Leopard-1s, and equip them with oldest ammunition types available that are not as lethal as later ones.
