It only takes a look through history to see who as a spotty oick teenager has joined the army after starting life as either an undesirable or from a less fortunate sitiuation who have through hard work and effort from both themselves and the army turned their lives around and made something of themselves. And in the process have made the lives of their country men what they are today
Like who? Got any examples? They'll be the one or two out of a few thousand that they use for recruitment drives in the economically deprived areas throughout the UK, where there are no other employment alternatives.
They don't show you the mentally ill, alcoholic/drug dependent schizos living in a box under a bridge (or a hostel/bedsit if they've done well). AKA the majority who go back to "civvy street", who'd planned at 17 a cushy life with no responsibilities and a lot of fun activities, to then retire at 38 on a full army pension but didn't consider the awkward bit, ie having to go and kill people and be crippled yourself, not just drive jeeps and HGV's for fun....
But then there are the fruitcases who relish the idea of being allowed to kill and not do time for it, beats getting life for stabbing someone down the local to satisfy their bloodlust.
