Delta 8O8
They can either be NCOIC's
but most of the time their official title is: "SNCO" aka Senior Non-Commissioned Officer
..just throwing that out there
It doesn't matter if there are 20 SNCOs, there has to be one with the title NCOIC or SNCOIC. Without the IC=In Command, then they can have someone they report to, and without an S/NCOIC, then even two S/NCOs would be a hassle to deal with.
SNCO doesn't mean anything except that they are an E7 or higher. SNCOIC means they are in command of the particular group they work with, even if there are three other SNCOs of the exact same rank.
I have a question for you, btw. What rank is that in your sig on that Gaia Military thing?
