I have an ex ranger on my team who is the most sexist, pompous, self important asshole I’ve ever met. By far the best bloviator and derailer of projects I’ve seen.
While I didn't serve, I did grow up with and had close family and friends that were part of navy, army and air force special forces.
The clown you describe does not last long in special forces unless he's a modern day Audie Murphy, Roy Benavidez or Chesty Puller.
