She grew up as a farm girl (no brothers) repairing farm machinery because her Dad was large and not very dexterious with his hands. Her appitude, background and small size made her perfect for the job. But she was more interested in just doing her job than in 'one-upping' the men in her unit.
Princess Elizabeth (before she became Queen) had a similar experience during World War II, albeit from an entirely different background. There is a famous story about the Land Rover that she and Prince Phillip were driving around in breaking down somewhere in the Scotland Highlands sometime in the 1960s and she crawls under it and fixes the problem while her husband simply handed her the tools.
I think the discussion was front line infantry soldiers, not of the mechanical skill positions. On the latter specialty field, I agree with you.
During my service time we had the WAC so I have no first hand observations and rely upon common sense regarding the infantry specialty. From my common sense, I feel that upgrading “dorms” including security monitors ( perhaps barracks” would be a better descriptor to the uninformed who wrote this article), to accommodate two separate sexes is a waste of money, time and energy unless of course they are planning on having separate squads based on sex in each platoon. This is insanity on steroids.
