What makes leaving the armed forces different?

In many respects, a career in the armed forces is unlike all other jobs. Military work can occupy 24 hours a day and seven days a week, and it frequently involves working, sleeping and socialising with the same people, in a 'self-contained social world'. With its ‘different ways of communicating and relating to others, different living arrangements, [...] and different standards of behaviour, dress, and bodily comportment’, it is often described as more of a 'life' than a job.
