The U.S. Army, Navy, Air Force, Marine Corps, and Coast Guard, in concert with a few faithful allies, performed amazing feats during the first three weeks of Operation Iraqi Freedom. Aerial bombardment obliterated key enemy facilities in Baghdad. Special Operations Forces and Patriot air defense batteries muffled ballistic missile responses. Spearheads sped north at breathtaking speed before logistical shortages and a blinding sandstorm made them pause briefly, then gutted Republican Guard diehards who guarded Baghdad's front door. Organized resistance in the capital city collapsed on 9 April, 21 days after combat began. Six soldiers remained missing in action when this issue went to press, but all seven U.S. POWs were safe. Coalition and civilian casualties were much lower than the most optimistic predictions. Countrywide mop-ups and counter-guerrilla operations continued, but full-scale warfare was finished.
