What makes leaving the armed forces different?

The military is often described as a 'self-contained social world'. It often implies a professional commitment far in excess of the traditional eight hours a day and five days a week, and usually involves toiling, sleeping and socialising with the same people – often in relative geographic isolation, during lengthy deployments, sometimes at short notice and habitually in extreme environments. 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.
