Have Military Law Questions? Ask a Military Lawyer.
Yes, there is. Your first step should be approaching your new command and asking that it fix the situation. If your new command either says it cannot, or just refuses to help, you can ask the Army Board for Correction of Military Records to backdate your promotion date to the earlier time.
If you Google the board, you'll find their website. The Board has the ability to correct many issues with military records, promotions being one of them.
The instructions for applications are on their website. It's a simple process to file an application.
