staff officer

I had a momentary mental picture of him as some Roman staff-officer rushing back to the base in his chariot.

The military chauffeur was not surprised either; nor was Captain de M., the French staff-officer who accompanied us.

I was on detached duty as staff-officer, and so got a leave of absence.

The staff-officer leads us half a mile to the right, where, sinking down utterly exhausted, we are soon sound asleep.
