The C-17 has already played a huge part in the war. They have been busy for months hauling troops and equiptment into the area. Flying the resupply to the troops during the war is also a vital role. Long after the war is over the C-17's will again be used to bring people back home and to bring relief aid and supplies into Iraq. The C-17 is busy doing lots of the work the old C-141's did in the past.
