What are the controls on battlefield bad company 2?

I play modern wrarfare 2 alot and im going to get battlefield bad company 2 in about a month(hopefully) and I heard that the controls are different, could you tell me what you use to shoot. aim, crouch, throw grenades ECT. Just about every control, I would like to know.What are the controls on battlefield bad company 2?
For shooting, ads (aim down sight). sprinting, reloading, and switching weapons is the same as any other shooter.



The only difference is the d-pads are for switching between your gadgets, LB for grenades, clicking the right thumb stick makes you crouch (unless you played with the tactic layout on MW2) and RB is for knifing,



You can set the controls up to where is works like the first one. (unless you haven't played the first one)



After that, don't worry about it. :D



I've had friends like you, but when they got on and had explosions and tanks and stuff happening around them, they tend to forget about it. XD
