Not wrong. At “best,” we’ll see a fracturing of the military…which could be much more trouble than it’s worth. I’d expect a small wave of resignations/desertions (since resignation for an officer takes a long time). The remainder of good people will actively try to avoid and sea-lawyer their way out of doing any damage to civilians without violating orders. There will be a good chunk who will happily fire on US civilians, though.
Yep, but those who resign for moral reasons will be more likely to take actual actions to protest/stop what’s happening. The military will have a hard time recruiting competent people in that environment, though, and the people taking the vacancies will likely have diminishing competence as time goes on.
To put it in perspective, if more officers retire at 20, they’ll generally be O-5s (Lieutenant Colonels or Commanders), and so the next year’s promotion cycle will need to promote more O-4s to cover the vacancies. This will then trickle down, and suddenly, you have officers who have been O-3s for just a couple of years being promoted to O-4 rather than waiting longer and gaining experience.
In that scenario, there will be less efficiency in planning and execution and far more incompetence, and if being used against civilians, more brutality. But incompetence is easier to defeat in the long run. Seeing the incompetence and brutality will deprive the military of the smartest recruits who staff the important IT, intelligence, cyber, etc. communities. So, while they may get true believers, a lower proportion will be competent.
No matter how it shakes out, it will get very bad.
