From the USA one of the WAVEs on related work recalled her induction in Washington DC ("I joined the navy to see the world, but all I saw was DC"), unfortunately I can'd find the reference, so I'm recreating from memory:
"We had a tough introductory talk about security. This was followed by another man, who we expected would give us a warm introduction, perhaps a prayer. Instead, he told us not to expect to be treated differently because we were women: If we talked about our work, we would be shot."
