Then.... Now.... 4-07-2004 GRIEF-stricken US Marines huddle together in prayer over the body of a dead pal yesterday. For a few precious moments of mourning the tough troopers turned from the fury of battle at Fallujah to bid him farewell. The Marines had fought hard to keep their buddy alive. They had bound his head wound after he was hit by shrapnel, then defied enemy fire to carry him to a first-aid post. But nothing could save him.
