batman
Pronunciation: /ˈbatmən
noun (plural batmen)
• dated
(In the British armed forces) an officer’s personal servant.
Origin
mid 18th century (originally denoting an orderly in charge of the bat horse 'packhorse' that carried the officer's baggage): from Old French bat (from medieval Latin bastum 'packsaddle') + man.

I can only assume that Batman's batman opened Colonel Bruce Wayne's campaign chest only when they were alone.
