Two U.S. army sergeants have been awarded one of the highest medals for heroism following fierce fighting against insurgents in the Baghdad slum of Sadr City, the U.S. command said Saturday. Sgt. 1st Class Jerry Swope and Staff Sgt. Robert Miltenberger, both with the 2nd Battalion, 5th Regiment of 1st Cavalry Division, were awarded Silver Star medals at a ceremony Thursday for "exceptional valor in combat during Operation Lancer Fury" in April in a Shiite slump of Sadr City in Baghdad.
