As in aviation, there's a formal process to rescind a warfare qualification (I.E. FNAEB). AFAIK, that has not happened for Greitens. Not being given an NSW billet as a reservist is a completely different matter.I thought I read an article that said when he attempted to re-affiliate with the Navy, the SEALs would not allow him back into the community. Interesting if they wouldn't let you back into the community they would still allow you to wear the Trident.
