It's an interesting idea that the military should "reflect the population it serves". I would actually prefer that it didn't! To my mind, it would be smarter if it reflected the job that has to be done.
I am also curious to know what impact removing 'traditions' such as uniform, saluting and other hierarchical manifestations will have on the ranks, as is being suggested in this thread. Have any behavioural scientists been consulted about whether it might lead to dissent and, ultimately, a military force in which it becomes a bit of a gamble as to whether a legal order will actually be carried out?
