Speaking directly from experience, that is all i had to do. I simply showed a copy of my current orders and my drivers license (from my state of record) and was issued a GA permit (GFL). My wife on the other hand (just a dependent) had to get a GA driver license before her GFL. I am not sure of the state where you are but I know the states I have been to and cared about that was the way it was. If unsure a phone call to the Sherrif's office, court house or DMV (depending on your state) is all it should take to know for sure.
