My only comment is that I don’t expect the “general population” to be capable of providing decent soldiers. A random selection of today’s young people seems likely to provide mostly headaches for anyone trying to whip them into shape — especially so when you cannot be mean to, or yell at new recruits.
My prediction is that if any draft is implemented with today’s leadership, it will be replete with exemptions for practitioners of all the currently popular peccadilloes.
