You can play this ‘game’ for two to three years, but as each year that passes, you are giving up permanent billets. So you might have a AF unit with 110 billets on paper, and six are permanently empty because the incoming recruits/junior officers....aren’t there.
Same issue with reserve/national guard.
If you tried to bring the draft back? More than 90-percent of recruits would be physically unable to meet standards, have drug issues, refuse to take orders, or ID themselves as mentally incompetent. It’ll be curious what you are left with by 2035.
