Yes, you can. I had many married friends throughout A-School. Once you show up you'll get a week to go get your wife and your household goods, then you'll either move in on base housing, which is very close to work, about a 2 minute drive in no traffic, or you can get a house out in town. Out in town can be a lot nicer for the same price, but it's further away. A lot of people actually end up getting married in A-School because your quality of life is so much better. People online will tell you about how hard it is and how you'll have no free time, but it's not that bad. You'll study more than anything else you've ever done, but even my friends who struggled through the program had some free time on the weekends, and had very happy marriages. Best of luck to you, and feel free to ask any more questions.
