No joke. During my time in the military the females proved to be a seriously catty, backstabbing group where other females were concerned. I didn't dare turn my back on any of them.

I was in when they still had the WAC and so I had no contact except with nurses. But my time in private industry has showed the same thing. Males are much more team-oriented and far less vicious in their personal relationships.
