A National Guard multi-purpose utility truck fords the floodwaters left by Hurricane Katrina to bring supplies to the Super Dome in downtown New Orleans, La., on Aug 31, 2005. Tens of thousands of displaced citizens sought shelter at the dome but are now being evacuated as floodwaters continue to rise throughout the area. Department of Defense units are mobilizing as part of Joint Task Force Katrina to support the Federal Emergency Management Agency's disaster-relief efforts in the Gulf Coast areas devastated by Hurricane Katrina.
