Neutral.
I want to remind people, that an admiral would usually be in command of multiple ships in a fleet. So they would be able to command more than the naval personnel on the ship. Also if since we look at the clone wars, yularen and skywalker always seem to,be work side by side of on another. He did the same with Obi-wan, and it seems almost the same thing happened with Windu and the ship’s commander, before boba destroyed the ship. While some may say the saying “sir” is towards the higher person in command, it is also a sign of common respect towards people along the same rank and some times lower ranks. If we look at a ranks of militaries across the world and through a lot of fictional military also, so to build on top of that, if you reached admiral, your at the highest rank in a navy, just like a four star general, or in this case, a marshal commander.
The reason that this is a neutral post is that since there is a shift to a new map and it’s a land base map, the navy has to change accordingly, which will force the admiral rank to change and will pull that rank down since it’s a base that a general would usually command.
sorry for this rather lengthy post.
