If you play the singleplayer you will gain exp and knowedge and yes in SP there is tips and guides how to do certain things.
I tried to google it, but nothing.
Is there any guide?Even a multiplayer-only (with HQ maps, tactics etc).
If I'm not supposed to ask that here, I'm sorry!
Stay focused, stay alive!
