WTF is "What bad on realistic weapon behaviour?" supposed to mean??
What language are you translating this from or is that how you write questions normally?

1 cm armour increments is standard for SP1 and SP2 AND THESE GAMES and that goes back nearly 30 years and it is baked into the code

BUT..

This is REALLY GETTING OLD..

Trucks can be destroyed by small weapons fire. "Armoured" trucks are assumed to be protected to withstand small weapons fire.

THIS is how the game works and most things you have posted prove you do not understand how the game works but think it should work the way you think it should work which is not how it does or will.

Maybe a long time player will have better luck but I am done trying
