My friends over at Straighterline.org have a great article on how their program can give military members an edge in earning their degree. Many Service Members may be waiting to get started on their degree until they get CONUS or waiting until a new semester begins - but you don't have to. Many college and university programs will let you start when you want to start. The beauty of Straighterline is that you can start when you want and finish faster - you take the classes when you have the time.
Take a look at their article for those looking at using the GI Bill for Education.
