My experience is that there are as many variations of SWO as there are of any rank and trade. The difference is that the SWO is in a unique position to 'set the trend' at a unit.
If the SWO is a bad un, it permeates through the entire unit but a good un is a godsend and can make a unit 'zing'.
When the current Mrs O-D was somebody in authority at a place not far from Oakham, the SWO was a top notch guy who was a character in every sense of the word and participated in most aspects of the social life of the station, casting off the SWO 'mantle' when appropriate (ie on the football pitch) and wearing it to full effect when necessary (Prisoner and escort, quick march!!).
Several days before the QBH List was published, the dear lady visited the unit and at the end, as her carriage taxyed for take-off, the stash turned to said SWO and said something along the lines of: "It's a couple of days early but Mr ????, you're to be awarded the MBE in the next honours list, come and have a pint!
