I stand by position that the US mil should be all volunteer; unless in time of war. Your example illustrates my position - in times of war cops and firefighters were drafted, which I did not know. But no in non-war times.
And I am not saying that all or any percentage of draftees were not qualified. But in any draftee situation some (whatever percentage) will definitely not be qualified, especially in terms of attitude.
Have you even been there and done that?
