Actually, I think this was discussed a while back, maybe years ago. I recall making the point that it was clear to me at least that they had to have some sort of integrated structure that merged two services (at least). Similar to what you see maybe with an expeiditoinary strike group today in the US Navy, where they have high ranking Marines in the command structure or even as the head honcho. I mean, it makes a bit of sense, Tigh is clearly a Marine, and the rest are clearly Naval officers.

At least, that's what I thought until last season, when, as you mentioned, they started mixing up Marine and Naval ranks all over the place.

So...my guess is they lost their military liason who used to tell them what was what.

Oh well, still a great show.
