Best bet would be to contact the Secretary of State in Lansing directly and ask them. They have been very helpful each time I have had a question and not like dealing with a gov't office at all. Actually nice and helpful without a lot of BS and hoops. Here is the link to their contact page:

If I remember right, you don't have to change anything as long as you are active duty, but it has been a long time since I knew active duty in the State. It may be to your advantage to change for price, depending on where you are coming from.
