Given that the army are taking the bulk of the casualties, and are arguably bearing the bulk of the overstretch it was a surprise to see that their morale is higher than the other services, according to the survey
Although isn't there an argument that the wars are allowing them the opportunity to get on and do what they joined to do - fight people with guns? I think overstretch features to some degree in people leaving, but it's a multi-faceted thing with not necessarily the expected causes. I would suggest people have a Pick n'Mix approach to their reasons - some fair, others unreasonable and overstretch isn't necessarily an issue everywhere.
