They were fixated on violence. My father spent four years at sea during World War II, first aboard the USS Greer in the North Atlantic, and then in the Pacific on DD-554, the Franks. He didn't talk a lot about it. Those were ugly days when blood ran on the decks and the kamikazes screamed in and you red-barreled everything you had at the nacelles and hoped you hit a fuel tank before the pilot hit you. I bet those sailors, mostly dead now, all of them forgotten, would be proud to know about Potty Consciousness.
Truth is, the military needs to be stripped of all manner of gender-unfriendly trappings.
The very thought must be offensive to women, and make them Uncomfortable. Submarines are nothing but nuclear-powered phallic symbols. I reckon we ought to have gender-neutral, cubic submarines. Flowered wallpaper would add a homey feel and, if you got rid of those awful male torpedo-things, there might be room for a shopping deck. The potty problem has reared its genderishly inequitable head for years in the mascara military.
