Default 5.56 vs. .223

I have been noticing that alot of the civilian tactical rifles are chambered in 5.56 and .223. What is the difference between the two.calibers, like in balistics?

5.56 is a higher pressure round than the .223. You can fire 223 in a barrel designed for 5.56, but you do not want to fire 5.56 in a barrel designed for .223.

Not to be a dick, but there have been at least two other threads on this exact topic in the last week. It is also discussed in the "AR primer" sticky thread. I don't understand that.

Here is one: http://www.firearmstalk.com/forums/f18/difference-between-223-5-56-a-78224/

5.56 is what real operators use. .223 is a much weaker round and isn't as good at killing terrurists. FYI Call of Duty uses guns chambered in 5.56. There's a reason for that.
