I think this article should be taken with a pinch of salt, as should most articles written by those "in the know" about HM Forces. It all depends on what you call sexual harrassment, for example is telling a blonde joke harrassment? I would say no, but to whoever made the survey it probably counts as such.
Despite my light hearted comment above I would hate to think that anyone in the forces is subject to real harrassment, though I'm not so naive to pretend that people aren't bullied somewhere in their jobs. I've shown this article to a couple of girls I work with and they both laughed and dismissed it as sensationalist propaganda.
But then again, an article on the forces just getting on with their jobs in a professional manner just doesn't make headline news these days.
