The following is an excerpt from a recent response to a person researching an individual who was killed during the war and interred in a common grave with others of his unit. This is to inform - or remind - that combat casualties weren't - and aren't - always as neat and photogenic as the propaganda photos and John Wayne movies would have us believe.
"Very Important!! Group burials result from inability of Graves Registration personnel to identify individual remains. Remember, these guys were in an aircraft that crashed - and probably burned - after falling from several thousand feet. Six men are listed on the grave marker because Graves Registration found body parts sufficient to suggest six individuals. Deceased files relating to group burials can be pretty graphic. Those who handle these files usually simply (1) pull the file, (2) feed it through an automatic copier and (3) send it out. There's usually little-to-no editing so be prepared for a shock - maybe a big one."
You might keep the above in mind when ordering deceased files.
