U.S. Military Dignified Transfer The backstory: The dignified transfer ritual at Dover Air Force Base is conducted for every U.S. military member who dies in the theater of operation while in the service of their country. The dignified transfer is not a ceremony; rather, it is a solemn movement of the transfer case by a carry team composed of military personnel from the fallen member's respective service. During the process, transfer cases draped with the American flag holding the remains of fallen soldiers are carried from the military aircraft that transports them to Dover to an awaiting vehicle to transport them to the mortuary facility at the base. There, the fallen service members are prepared for their final resting place. The Source: This article includes information from The Pentagon, the U.S. Army, and previous FOX Local reporting.
