Sixth amendment rights in the AR 15-6?

I have a question and not really a response. What are your options for “rebukes”? For example if a soldier claims you hate Hispanics can you have Hispanic character witnesses to refute the claim? And at what point do you request to see your accuser?

It's my understanding, in the case of AR15-6, witness statements are obtained in the investigation process. This information is shared with the JAG attorney from the authority performing the investigation. And through that JAG Attorney the accused will see the statements, and have a chance to rebuke and request their own witnesses. I have been brought into an investigation of another soldier for sexual misconduct with a minor. I myself having children that had been around the soldier being accused, I and my spouse were requested to give a statement for the investigation and were called to testify at the court martial. The accused was prosecuted under Civilian Criminal Courts and UCMJ, the latter took precedence.
