Does concealment and cover stack?

[NeoNick]

As in the title I wonder if concealment and cover stack?

I may be missing it but when I read PH on page 280 and 281 I cannot find anything that implies it shouldn't. But I want to ask anyhow as 4 ed sparsely gives big bonuses/minuses to attack-roll and the stacking can make a huge difference.

Yes. Cover and concealment stack. They incur penalties, and penalties always stack.
