Army Hits Republican Guard "U.S. Army units attacked the Iraqi Republican Guard for the first time yesterday south of Baghdad, while enemy paramilitary units doggedly refused to let go of the strategic port city of Umm Qasr. In the land engagement by 40 U.S. Army Apache helicopters, ground fire brought down one chopper. Its two American pilots survived a "hard landing," only to be captured by Iraqi forces, becoming the war's first allied aviators taken as prisoners of war."
