For whatever reason (probably another topic someday) the mainstream media (aka the alphabet networks and certain newspapers with national distribution) is slow to report any good news from Iraq or Afghanistan. You can go straight to the USCENTCOM home page or subscribe to news feeds from them or from Defense Link and get the official information. Of course, some distrust the government, so you could also go to the military blog site for videos.
If you prefer a non-government view, try Iraq The Model. This site provides commentary and insight on aspects of the conflict that are not reported elsewhere. Since the bloggers are also graduate students, they have begun posting less frequently, but what they say is worth reading. Then there is Michael Yon's excellent photojournalism.
For a lighter look at the war, one of my blogging buddies has posted excerpts from another real buddy currently serving in Iraq. You will enjoy it.
