We’re a huge nation of 320 million souls. I can’t imagine a situation where we’d need to use females in those roles. I’d rather see a foreign legion before that.
There isn't one. The purpose of girl-Rangers, girl-SEALS, girl-mariners, and girl-aviators isn't the protection of the country. There's nothing any of them does—and this also applies to female cops or Guardsmen—that couldn't be done better and with less compromise to their unit by lots of males who would be glad to take the job. Coed protective services exist so some women can feel they have a life. They don't think they do, because they have no respect for . . . women. This applies to some—but certainly not all—females in the service. It applies mostly to civilian females—especially politicians—who are burned up over the idea that men can do things that women can't. It doesn't appease them that women can do things that men can't. Their self-loathing doesn't allow for that.
But delusion makes bad policy. Breaking things and killing people on an industrial scale is a male thing, and that's that. As far as I know, both the Israelis and the Russians gave up the girls-in-combat thing long ago, because it was a disaster.
