I have not watched much on this game, but I'm going to assume that you can't.
It really annoyed me that in the first game you could drill a massive hole into the side of a wall but could not shoot through it.

Dude you can shoot the walls down.....  then you shoot through them :)

yes you can drill through walls and shooterize people on the other side in bc2

So I guess my assumption was correct then? There is no shooting through walls. 
Lame.

Lame is the correct thought. Unless you could shoot through 3 houses, 1 brick wall, 2 people, and 1 chicken and then hit someone in the head with that same bullet like in CoD4 and MW2. :P

You can shoot through certain things, you definitely can. I killed people shooting through a wooden fence, and light metal crate thingies before. Actually unsure of walls, I naturally didnt try yet since it wasnt in the first. Maybe I can find out later sometime.

@imhuntad:
Yeah I was joking too. Do you remeber the part in CoD 4 where you in a flashback playing as Price? I wanted to say that for comical relief.

So I haven't seen it definitively denied yet. Just folks saying "why shot through when you can blow up the wall" or "you can shoot through thin cover" which doesn't really answer the question.
 
Can anybody in the Beta do some tests explicitly on walls?

you dont shoot through walls, you destroy them

Yet another non answer. Please, people!
 
The question isn't about micro-destruction, it's about bullet penetration.

There is bullet penetration, but it is not nearly as flimsy as Call of Duty plays bullet penetration.  In Call of Duty, there might as well not even be walls....just a flat area for you to shoot each other on.  In Bad Company, you could shoot through some thin objects, and the closer you were to a wall, you had a better chance of being able to get more bullet pen.  There's an actual volume to bullets in Bad Company. 
 
In the end, though, it doesn't matter...because the Bad Company franchise blows shit up real good.  Now that you can collapse buildings, who gives a shit about shooting through a wall except folks who can't play a face-off against another player? 
 
Seriously, FPS gamers nowadays just wouldn't survive in CoD2 or UT2004 or Quake III nowadays.  They'd whine and bitch so much that they can't shoot through walls.

well yeah that's kinda it's selling point

COD penetration is indeed pretty absurd, but it's better to have it than nothing. Most games don't treat it realistically and allow perfect piercing (without deviation) until the bullet just 'disintegrates' after a certain range
 
Optimally the bullet trajectory would deviate upon hitting the surface, and the amount of deviation would depend on range, bullet type, velocity, angle, and surface material (including the possibility of ricochet). With such a model the headshots through concrete often found in MW2 wouldn't be nearly as exploited.
 
But the idea of "blowing up a wall is always better than penetrating through it, no matter what circumstance" isn't a well thought one. The kit doesn't always have the option of blowing up a wall just to kill the guy behind it.
