Just as a general observation from my time as a flying instructor in the Forces and that’s there is not automatically or necessarily any overlap between the personal attributes needed to be a pilot of an attack helicopter/fast jet, a high achieving scholar or a successful business person, but being genuinely “thick” would rule you out of all of those occupations.
For info sadly many graduates fail flying training (classroom skills only get you so far), some business people fail training, even worse a few pass and then kill themselves because they let ego get in the way of sensible decision making…
According to all credible sources I’ve seen and heard from Harry passed wings and managed to hold down two roles on the Apache (BTW a co-pilot in any aircraft is a genuine qualified pilot, not some form of lower ranking assistant) so I’m not convinced he is quite as “think” or “stupid” as some try to paint him, or at least wasn’t when he was serving.
OTOH I get the impression it is possible he lacks motivation and is generally aimless unless kicked by NCOs, Senior Officers or men in grey suits.
As for the circumstances of his leaving HM Forces… he’d followed a fairly normal career path by doing his specialist junior officer operational tours in his twenties. The usual career pattern for those that want to stay on in HM Forces as they age is to move into more of a management role, and yes, that might mean exams….if you don’t fancy that then often the only other option is to leave.
As a result of the above over the decades many many junior officers have opted to leave the forces in their early thirties and transition to some role in civilian life.
The vast majority of those that do leave HM Forces don’t belly ache about it, they usually make the transition to civilian life successfully despite not having a second career lined up for them by Pa and/or without having their hands held by men in grey suits…OTOH despite having such assistance Harry doesn’t seem to have managed it. Why?
To be honest I look at Harry and I don’t see someone who is obviously thick or dim, but I do sense I’m seeing someone who is (?still) aimless, lacks motivation and possibly has a massive sense of entitlement on top.
