The soldiers are: Specialist David W. Yancy of Ripley; Specialist William E. Brooks of Southaven; Sgt. Leonard A. Casper Junior of Myrtle; and Sgt. 1st Class Wyman C. Floyd of Hattiesburg. The men are all members of the 155th Brigade Combat Team. Brooks' mother, Carolyn, tells The Associated Press her son was the worst injured. She said quote -- right now is he is in critical but stable condition. He had both legs amputated below the knee. Carolyn Brooks says the four soldiers were in the same vehicle near Baghdad when the explosion occurred. Yancey and Brooks were transported to the Landstuhl Regional Medical Center in Germany for further treatment. No further details of Yancey's condition was released. Floyd and Casper were expected to return to duty this week.
