Here is a quick run down of a few things that you are going to want to start a handy dandy deployment binder.
You can request a Deployment Kit from USAA here. Some FRG's will provide this for you. I didn't want to use this big bulky thing, so I used some of the info and put into my binder.
Power of Attorney: You want a General POA for sure. Don't forget a Special POA if you are planning on any major purchases while your soldier is gone.
I had my man get a special POA specifically for taxes and one for anything dealing with the house. We own our home and I just wanted to have it JUST IN CASE something was to happen.
Passport: I still haven't taken the steps to do this, but I do recommend it. If your soldier gets hurt in combat, they are most likely sending him/her to Germany. If you want to be with them, you need your passport!
Customs forms: You know how friends and family are always asking, "Hey get me ________'s address & I'll send them a box!" but when they get to the Post Office many are faced with the challenge of figuring out a customs form. Filling those babies out are second nature to many mil spouses, but not all civi's know what its all about. What I do at the beginning of each deployment is go to the Post Office and grab a handful of forms and fill out the addresses in advance. I try to keep them in both my binder and in my purse. This saves the lovely friend wanting to help out, the headache at the Post Office and its a lot easier on me as well.
Soldier's ID: Copy his/her Military ID front and back as well as their drivers license. You just never know what you will need! {{{Having a copy of military ID is against DOD, do this at your own discretion. We have needed it in the past, but often times you are fine with just having a copy of his/her state ID}}}
Red Cross Info: In case of an emergency, before calling your local Red Cross chapter make sure and have the following information handy: servicemember's rank, address (unit, company and location where he or she is stationed), social security number, and branch of service.
I keep a copy of all this in my binder just in case something was to happen to me. I have also told a trusted friend where my binder is if she needed to be the one to contact him.
FRG info: I, for one, am not big on the whole FRG thing. I know they are there for a reason and they are a very important part of the military. They are there to help! I recoment keeping the phone tree roster in your binder as well. You may need to contact someone if they have not contacted you about Home Coming information. No one wants to be the spouse not at the dag/hanger/field when your honey gets home. TRUST ME. It almost happened to a friend of mine a few deployments back. Right, Rain.
There you have it. A few tips that have helped me in the past. This is a tried and true method of keeping all info right where you know where it is.
Reminder: You will have sensitive information in here. Keep it in a safe, but convenient place.
