The United States Central Command, aka CENTCOM. - More news straight from the horses mouth.
Multi-National Force Iraq - Just what the name implies.
Michael Yon Online - independent journalist imbeded with forces currently fighting in Iraq. His dispatches are carried by several major media outlets, but he is supported by donation.
I think that's enough to keep you busy all weekend.
