The men traditionally attracted to the military are staying away in droves. From John Haughey at The Epoch Times at zerohedge.com:
The directive came from the top: A memo from the U.S. secretary of defense ordering Pentagon leaders and the commanders of the six military branches to review and recommend changes to “policies, programs, and processes that may negatively affect equal opportunity, diversity, and inclusion for all our people.”

A month later, the secretary issued a second memo, titled, ‘Immediate Actions to Address Diversity, Inclusion, and Equal Opportunity in the Military Services,’ outlining a “three-pronged approach” for implementing those recommendations.
The secretary called for reviews to ensure diversity in promotions, prohibit pregnancy-based discrimination, bias awareness, “bystander intervention in response to improper remarks or other communications made by peers or superiors,” and a Workplace and Equal Opportunity survey to “include metrics concerning harassment and discrimination, extremist groups and activities.”
The Secretary was Mark Esper. The President was Donald Trump. It was the pandemic summer of 2020 and there was violence on the streets in the wake of the death of George Floyd.
