As mentioned I was not trying to be insulting and do not doubt your abilities on RAF aircraft. Prior to my lobotomy, I had 12 years doing similar work to you, before another 12 years being an Eng O.
However, you missed out procurement at DPA, R & D or military specialist at QinetiQ or DSTL, role offices in HQSTC, secondment to industry teams. As an eng o, I had to write cardinal point specs, judge on competitive tenders, attend equipment and system design reviews, provide MAR recommendations, conduct flight trials, let contracts. Admittedly, this is not hands on in the context that you mean but there are more elements to being an eng o than dismantling aircraft.
Fortunately, I managed to avoid MT and the support sections.
