I understand they were offered a Captains Mast (Article 15), but they turned it down. My guess is that this will never get to trial.
Yes: This is the reason I dont buy the allusion that this court martial is to protect the Seals.
They were offered a Captains Mast and they refused it, and asked for the court martial.
They were offered nonjudicial punishment. Since they refused they will automatically receive a courts-martial.
There are other charges such as giving a false statement and obstruction of an investigation.
They may get off of the assault charge but the other charges I’m not so sure.
