The National Infantry Museum at Fort Benning has officially opened, with retired Gen. Colin Powell speaking at the grand opening. The four-star general and former secretary of state joined other dignitaries Friday at the $107 million, 190,000-square-foot museum honoring the 234-year history of the U.S. Army Infantry. The building contains a 13,000-square-foot hall with six galleries covering battles from the Revolutionary War to Iraq. Outside, Gen. George Patton's original office and sleeping quarters are found on World War II Street, which also displays 1940s barracks, mess hall and other buildings moved from their original locations on Fort Benning.
