From what Iv read everyone has covered a lot of what you are asking.
I was a Seabee and very proud to have been. Just having that on my resume
got me work in the civilian world and I have no regrets. For an outfit that as far as history goes, they do not have a long history but they have a very proud one,and have accomplished some really amazing things the Seebee museum in Port Hueneme is one of the best museums I have ever been in, and covers that history, and just a walk through it would make anyone proud. I would recommend them to anyone looking to join the Navy. Everything you would learn
with them will always translate into the civilian world.
But one thing you have to keep in mind your husband would be taking a job you cant quit. If he ends up hating the military way of life It could make for a very bad time, and the stress that It will put on a marriage, and it will put stress on the marriage is extreme. So be very careful what you and he do if this is done just for economic reasons it could be the worst thing you could both be doing. Most marriages end because of money problems. Then add to that extended periods of separation that could be months and even years.
So what seams to be the answer to a problem could only make it much worse, and be regretted in the end.
Then to end it all regrettably America has a bad habit of relegating its service men and woman to the lowest rung of society,when their time is up and they have given so much
Just look at the numbers of homeless vets.
So please take your time and look at all options and some you may not have thought of.
