Have you looked into how the military was professionalized in the 1960s/1970s? Military academy slots were valued and given to sons of prominent individuals. Universal conscription was acquiesced to, perhaps because service in the military was not a horribly low-paying job compared to the value that the young men could provide to their family through their labor on the family land. Officers were sent abroad to the Soviet Union for professional education. Obviously, recreating that system might be difficult, but there might be lessons that can be gleaned from the old system.
