The US military is actually surprisingly decentralized, with a lot of leeway and authority given directly to NCOs, and officers routinely getting ignored, circumvented, or subjected to malicious compliance if they even order something considered unreasonable, much less illegal. Also see: fragging. Malingering. Mutiny. Desertion. And the worst nightmare - Insider Threat. So much of the military runs purely off of trust, faith, and compliance to words on a page.
You think Don’t Ask Don’t Tell was actually fully complied with? Sentries already fall asleep while at their post, willfully, without needing to have any excuse other than being tired or disliking the watch officer. Roving patrols routinely miss rounds, don’t actually pay attention or inspect anything, and practice what we call “blazing logs”, that is, writing down “all conditions satisfactory” without actually looking at the conditions. Maintenance also gets blazed all the time - technicians just straight up not doing the required maintenance and writing down that they did, substituting unauthorized materials, or half-assing the maintenance. Paperwork just gets “lost”, or never gets signed, never gets filed, never makes it to the intended recipient, just because the admin secretary doesn’t feel like it. Information isn’t entered into a system, including disciplinary or otherwise disqualifying stuff, because the admin or command likes you or needs you.
Purging the upper brass won’t do anything to circumvent or “fix” any of that, it’ll make it worse, because it’ll incentivize the servicemembers to do it even more. The E-4 Mafia will straight up disappear when needed, entire supply chains will stop cold. Separation and disciplinary paperwork will just not get sent.
