From my experience the key is building the business. The military of the future will have to work on commission based hits. In addition the military grunt will have to recruit grunts on the streets, turning them into net soldiers and earning commissions from his recruits' hits. They could do it on a volunteer basis and part time or full time.
This could be easily done, I wonder if the Pentagone thought about it. Building a business and using IT tools to leverage industry and war making is key. We cannot enslave ourselves to human resources either, robotisation is a must.
So, a MLM (multilevel marketing) military is what we need for the next war, eh? You guys never stop dreaming of ways to expand and make a buck, do you? :-)
