Deployment and Wedding Dates?!

Honestly, you might not find out the date of the deployment until less than 30 days beforehand. I would really suggest talking to his superior or whoever is in charge of scheduling asap. We picked our date a year out and my then-fiancé went to the scheduling office and got it on the calendar then. Basically, he scheduled himself for leave a year in advance. If you talk to the right people, I'm sure they'll be willing to work with you.

In terms of before or after, I would say before just so you don't have the anticipation of a wedding hanging over you the whole deployment but after would work well if you think you'd have more time to plan while he's gone.

I would say before. My cousin planned a June 2002 wedding. Then 9/11 happened. Found out Jan 18 she was being deployed, got married Jan 19, shipped out Jan 21. They decided to get married before she left because if anything happened he would have spousal benefits and military health insurance and also active duty incentive pay.
