How are the bodies of World War 2 cleared?

The allies moved the bodies to gravesites after they were identified. If they could not be identifed they went into graves for unknown soldiers. Even body parts were identified and buried. Some could not be recovered because bombs incinerated them. The Germans were not so civil nor were the Japanese. Many bodies were just dumped in large mass graves or incinerated. When they had to clear bodies out of bombed buildings they carefully sorted through all the rubble and pulled the bodies out. Efforts to identify and count the bodies was done before they were buried or incinerated. The Japanese buried their own people as they went through the rubble and burned out places. They practiced their ceremonial rites for the dead.
