Wikipedia seems to align with my memory: Seagull = Adjutant (flying around and sh*tting on subbies

)

I think that there is a bit of flexibility here varying with the functions each appointment fulfills in the battalion/regiment.
In the artillery there was an Adjutant (basically paper pusher who rarely if ever went into the field and whom we didn't trust with a radio); an Operations Officer (who accompanied the CO and ran the FSCC at brigade level); and a Regimental Command Post Officer (RCPO - who basically coordinated the regiment's fire and anything having to do with the gun lines).
In all units I was ever in, the RCPO was "Seagull" (as were the battery Command Post Officer and later when we went to a single six gun unit, the Gun Position Officer - we flipped things, in the two troop system the CPO ran the battery gun line and the GPO a troop gun line; subsequently in the single six-gun battery the GPO became the senior gun line officer and the battery CPO and battery Recce Officer the two juniors)
My recollection was that the Arty Rgt'l Ops O went by the appointment title "Acorn" as he was the nearest thing we had to an intelligence officer.
All kidding aside, the Adjutant was "Manhole" and the RSM was "Manhole Minor". All this is set out at Figure 7-7 of B-GL-371-004/FP-001, Field Artillery Vol 4 Duties at Regimental Headquarters and at the Gun Position.
For bonus points, does anyone know who the appointment title "Conrod" refers to.
