Thank you for the information and your question. The CID record is there because they opened an investigation into misconduct. So, it is like with any other law enforcement agency where someone was arrested or charged with a crime, even if the disposition is a dismissal or not guilty. So, this should not be showing up as a conviction, but instead an open investigation or arrest. If that is the case, then there is nothing you can do to have it removed. In other words, there is no expungement of correct information in the Federal system.
The proper way to handle the report is to divulge that you were investigated and then produce your military record and shows you were not punished or court-martialed. Again, like other persons who have charges or arrests on their records, who sometimes have to explain the disposition. This, however, if not a conviction, so it shouldn't effect your employment.
If the information is incorrect, then you can petition, the Army
Board for Correction of Military Records to have it removed. You can find out how to submit your request by going to: http://arba.army.pentagon.mil/abcmr-overview.cfm
Please let me know if you need any clarification. I would be glad to assist you further if I can.
