I was just wondering becuase I have heard from a lot of people that they only attach you to the unit and not PCS your family.Currently I am active duty in a WTU. When you fill out the packet you can request which WTU you would like to go to. It is not guaranteed that you will get that WTU, but you can request it based on the medical treatment, or if you have family support in the area. If you get approved for the WTU you will PCS and your family can come with you. Me and my family reside off post and my wife attends my appointments with me for help and support. The WTU process can be quick, a lot of it depends on your command and med team doing the paperwork correctly and it getting approved. Best of luck let me know if you have any other questions.
