Apologies if he has already been referred to but one who stands out in my memory is WO Ireland who was CWO at Sleaford Tech in 1979 when I was on 36 IOT. Subsequently bumped into him again at Laarparts in 1981 - a rock and a tough one at that but was great fun to be with socially. Had his share of personal tragedies - son killed in NI on active duty.
We took the seniors out for drinks before graduation and he noticed my non regulationary neckline hair cut - he warned me that he would find me the next day. At the Sqn pre-grad phot and just as I thought I had got away with it, felt this pace stick going up the back of my neck: 'What do you think you are doing at dinner today Mr Bladdered' , 'not much Mr Ireland', 'well the station barber is expecting you Mr B and your f.....g late, move.......'.
