The cases identified tend to be in Africa and the Middle East I believe. The Menin Gate has the names of eg Indian soldiers who died thereabouts by name - and even a few "Camp Followers" are named. The Committee responsible for the war graves etc away from the Western Front appear to have had different standards. What they clumsily tried to do was to take cognizance of local conditions - some cultures do not bury their dead or use individual headstones etc. What is unforgiveable is the lack of individual names on a memorial of some fashion.
