Why is it that so often a really good bloke as a major, easy going; sense of humour, perspective and proportion becomes a complete twat on promotion to Lt Col in command? The same bloke inevitably turns into an amenable member of the human race again on further promotion - seemingly having just taken a short "carreer break" from the human race for 2 years (with some notable exceptions). Is there a bit in the CO Des cse that says that's what they've got to do? Example - a CO I know commented once that, even though he was commissioned with and had served almost all his career with, a certain individual, now that he was CO and this bloke was still a Major he would expect to be referred to by him as Colonel or Sir at work (fair enough perhaps) but also in the informal social environment of the CO's or the Major's home. What's that all about then?
