What has me saying huh to the whole thing are the berets. Is that now authorized in the Riverines? Also notice the insignia on it. Additionally check out the patches on their left shoulders. "Don't tread on me" popularized by the Navy SEALs.
Despite being combined with Master at Arms for the port security mission it really looks like they're pushing real hard to be a quasi infantry force. I don't know if I'll be watching them but they have peaked my interests. I wonder what the end goal is.
