A few years ago I worked as a telecoms engineer. The role itself was pretty free-roaming and a large part of your working day was unsupervised and allowed you to make your own decisions and your day to day achievements were pretty much all down to you and/or the guys you were working with.

Anyway, the company had a spell where they hired a lot of ex armed forces personnel into various engineering roles, many of whom had done long stints in the military. Pretty much every veteran I worked with was smart, hard working, organised and a joy to work with. With one caveat, most of them needed an 'order' to do a particular thing, or pushing into thinking for themselves. They had spent their entire working life in a structured, order based environment, that left them unprepared when they were given the freedom to think for themselves.

I can totally get how homelessness and addiction problems can beset people when the structure they have spent their whole lives within, is suddenly not there any longer.
