Does anyone have good advice on what to do for my wife before I get mobilized?

Excellent Question 1LT Jeremy Janulis!

Please ensure she has total access to all finances. Make sure your Will is up to date and written the way you want. Give her all phone numbers for your Unit’s rear detachment. Encourage her to take time for herself. She is going to need a good support system in your absence. If you have children, please talk to them before you deploy.

Your family is naturally apprehensive about your deployment Everything you are able to do to reassure her and them will make this transition earlier for everyone. Best if Luck and you might want to encourage her to establish her own account on RP

First things first, Sir, is to see if your unit has an established FRG. If your unit does, have your wife get in touch with them. There will also be a Yellow Ribbon event. I HIGHLY recommend your wife attends that with you.

Dishes?? Just kidding, ex and I were both serving Navy officers. We always seemed to be coming and going. We decided that for sanity, we would reserve one night for a good dinner out together. No talk of deployment, no worrying about what was to come. That way, when things inevitably get stressed we would always have that night to remember the good times.
