Do you by any chance have any proof of the coms at the time?
Do you know that you are responsible for who you shoot no matter what another person tells you?
The viddo you uploaded does not match what you said in the incident description. All i can see is one of them saying "we are going to the admins, your fucked bro"
Do you have any evidence of the metagame you claim etc.... ?
Seeing that no evidence can be provided, I'm going to have to close the report.
You could post on the UNMC military justice board, but again I think they will require evidence.
