I am pressed for time just now, but.

Talked with my Dad and a couple of things he mentioned may help as far as the US forces are concerned.

First, no batmen as such.
Officers of field rank, Major and above, were assigned something called orderlies who provided, as far as my Dad was concerned, more or less the same services as a batman in the social sense.
The same rank of Officer was almost always assigned a driver who was also reasonably responsible for making sure his Officer was safe.

Orderlies were apparently assigned on the basis of "who is available at any given time" and did not necessarily serve a given Officer for any length of time unless there was a bond formed and the Officer arranged for a "permanent" assignment. The same was true for drivers but drivers tended to get attached to one Officer for the duration of a campaign and sometimes for the duration of an entire conflict or even the whole war.

The term I used earlier, "Stewards" was a Naval term and seemingly only used by the Navy and Marine Corps. Stewards were more or less a sort of male domestic servant, to use the words a bit harshly, and my recollection was that was pretty much what the Stewards that my Dad had did in terms of their job description. Housekeeping, housecleaning, babysitting, bar tending, car washing and so on.

Finally, it was Congressman Les Aspin who put paid to most of these traditions, particularly Stewards and whatever the equivelant title the Army and Air Force used and the Services became a little more Politically Correct. From what my Dad said, this occured in the 1970's as far as he can remember.

Another little historical footnote.
