Given that the role of any military force is to prepare itself to win wars and not come second, the selection process should reflect this aim by ensuring it has the best available personnel. The model that comes to mind is our national athletics team where, for instance, the 4 x 100 team is normally nearly all black because they are the best and that is who you want if you are to win. There is no suggestion that this team should reflect the ethnic mix of the country as this would inevitably make it less competitive, similarly we should not undermine the warfighting capability of our forces by imposing arbitrary targets for race, sexual orientation or gender.
