I know this is an odd question. But surely there are some officers out there that would wish to stay as Lieutenant/Captain/Major and not go higher? Are they forced or coerced to promote in any way if they would rather stay doing the more 'interesting stuff' on the 'frontline'? (Infantry). I just can't help thinking some officers feel they would not be happy going into a staff job. Also, do officers move from regiment to regiment often to gain a more general grounding? Or can they just choose to stay in their original regiment if thats their wish? Thanks.
