I have a friend who was a Captain in the Military Police, until she was forced to leave when her commanding officers found out that she is gay. She had been doing a sterling job for many years, always praised and promoted, and had been gay all that time.... it hadn't affected her ability to be a good soldier in any way.
Personally I can't imagine why anyone would want to join the Armed Forces but I find the idea of actively encouraging a particular group to enlist just to widen diversity in the ranks quite off-putting.
Don't knock people who wish to join the Armed Forces, just because YOU don't want to!
How can you possibly know what it's like unless you've 'been there, done that'?
It offers much more to people than 'civvie street', one learns trades, & accomplishments, superior as well.
With free medical, dental, eye care, low house/rental costs, travel far & wide, it's an attractive employment to 1000's, thank goodness.
Be a shame if they all had taken on your view, VerityG
