Ask HN: What do you think of the expression “military aged male”?

Considering the current Russia/Ukraine conflict, and the wartime travel restrictions for men, it feels relevant to ask this question to a wider audience, regardless of whether they are pro anyone, neutral, or feel mostly clueless about the war.

Is "military aged male" a morally legitimate phrase, to be used without further criticism, or should the expression have the same negative connotations as the various types of social repression against women?
