In his second post, page one, New_WO1 says:
As a WO1, I'm not a Commissioned Officer but I am an appointed Officer (by Warrant) and a member of the O Club. On promotion to CW2, I will receive a Commission, so I'll be a Commissioned Warrant Officer
So by his own admission, he's not (yet) commissioned. Midshipmen would have got laughed out of the docks taking his attitude, IMHO
Followed by a digit or two as a salute
