I'm a female Mechanic at prototype; I'll be moving to report for sea duty in about a month.
I wish I could serve on a submarine, but in order to explain why I would have to compare the submariners I've met to the surface guys, and usually that starts an argument. (At least it does at prototype.)
Most female mechanics put in for ELT-I will not be an ELT. Uhmmm we have to stick together through some things, like pregnancy is a rough subject. I had a pregnancy scare not too long ago (I'm married-so not too big of a scare) but it winds up being a touchy subject, because we can't do our jobs when pregnant. They were going to yank my TLD (you'll learn what that is if you don't know), so I couldn't be on the boat and wouldn't be able to qualify until the child was born. On week 20 of a 24 week stint, that sucks, because I'd be starting back over. A Ma'am pulled me aside to "give me counseling on being a woman in the Navy", and she gave me some legitimate BS about how it's practically dereliction of duty to start a family right now, and was I not aware that I signed a contract? (She's wrong by the way-you're well within your rights to have a family.) I asked a surface guy what he thought and he told me plainly that women should not be in the nuclear field, with that being a primary reason. He continued by saying, though, that women belonged in the home and that I couldn't be a good mother and a good sailor...so I'm pretty sure he's wrong too.
What I'm trying to say is that there are some double standard expectations, and some women will be your friend and give you sound advice on what to do, some will try to be the poster woman by trying to trump the double standards. No kidding, the ma'am who tries to do only what she thinks others what women to do in the Navy is rumored to have slept around on her carrier and is getting surgery to better fill out her uniform.
You have to be strong and confident in yourself. If you're not sure of what to do, ASK.
But I don't have very much great advice yet; I've not been in this field but almost two years. I will help in any way I can.
