Sorry parabellum, bit of a pavlovian response from me. Having suffered through one particular outfit which had been taken over by ex mil types who thought that anyone who had not followed their exact career path was in some way morally and professionally suspect I tend to react accordingly.
Mind you I'm not sure that a load of embittered ex squaddies would really fit the bill either. How about selecting people on the basis of their ability to fit in? Flying airliners does not really call for the ability to dodge missiles or SAS survival techniques as a prerequisite.
