Seven sets of dog tags, boots, rifles mounted into the ground with fixed bayonets, and Kevlar helmets were used to represent six Marines and one sailor at a memorial service at Camp Al Asad, Iraq. All seven died when their seven-ton truck, part of a Marine combat logistics re-supply in Iraq's Al Anbar Province, rolled over during a flash-flood April 2.Hundreds of U.S. Marines, sailors, soldiers and civilians attended a memorial service for the seven fallen U.S. servicemembers, who died earlier this month due to a vehicle accident in western Al Anbar Province, Iraq. Following the memorial service, Marines, many in tears, approached the seven-rifle display to pay final respects and give final, silent 'good-byes' to friends lost. Some took photographs from afar of the memorial display, while others touched the boots or gripped the dog tags -- eyes closed and heads bowed -- to offer silent prayers. All seven fallen Marines and sailor were part of the Camp Pendleton, Calif.-based 1st Marine Logistics Group. A memorial service for an eighth Marine, who was with the Hawaii-based 3rd Battalion, 3rd Marine Regiment and was killed in the same accident, was held at the Marines' base in Haditha last week.
