The military has been shifting to demographic and gender blinded promotion systems, like this for example: https://hbr.org/2020/11/reinventing-the-leader-selection-pro...
It is in no way the case that affirmative action is being used as an excuse to promote incompetent officers, let alone that this is somehow destroying the military. In fact the military historically has had the opposite problem. "Legacy" counts for far to much, particularly with the families at military academies, leading to a senior leadership structure that is very out of step with ordinary Americans, and fails to grapple the cross cultural international issues inherent to the US projecting military power globally.
Stop disparaging our military with your alt right fantasy nonsense. The rank and file certainly don't deserve it.
These things usually boil down to money and power, not {{cultural_issue_of_the_day}}.
