If you need to talk with any questions you can pm me anytime. My hubby is in the Army and I am in the Air Force. Like mary says it is tough but in my opinion it is well worth it. Yes there are soldiers over there and what not but anyone can die anytime. I knhow that sounds harsh. My hubby is getting ready to leave for his second deployment.
Now I dont know that much about the Marines i do have a cousin and my step brother is joining the marines. Even though I told him to talk to the recruiters of all branches.
To be honest is he dead set on the Marines if so why that branch. I would definately go with him to talk to the recruiter that will help you a lot. Also see if he will talk with other branches of the military. They are all good. I am biased as i prefer the military as i been in 8 years and only deployed once

and it was only 4 months unlike the marines who do 6-8 months and the army who does a year plus. Each branch has benefits. As Bristol will have medical and if you two were married and you are moving with him you can get on post housing which sometimes sucks but when you are starting out its good. (dont get married just for that though).
I noticed that the Air Force is VERY family orientated unlike the Army (maybe its just my husbands unit) The Air Force no matter where i go always let me take care of my kids when i need to with no questions asked.
I am rambling now but the military is my life

so like i said if you have any questions what so ever do not hesitate to ask me. I have experience with being in as well as a military spouse.
