[@phillmyster] I might make both a pirate and a marine, if I do I am okay with grouping up.  As for your question  the Marine bases seen so far had a name consisting  of G and random numbers, I think

Pretty sure only Marine Bases that are based in the Grand Line that have the G-[number] as a base name. The four seas have Marine Bases that are [number] Branch (like 50th Branch or 80th Branch).

Although, some of the bases haven't actually been named yet, so I could be wrong.
