>Ah, quartermaster corps :o) I worked for the S3 and later the G3 for a time. That was in my aviation days before MI. It was an interesting assignment. Are the Belgium levels denoted by size? In the Army, S4 is Battalion/Brigade level, G4 is Division level, et al:

Not as far as i'm aware of. As i said S4 = army, N4 = navy. Dunno about the airforce.
My father was an S4 and that was on division level.
