Probable Enlisted Ranks re-imagined "Battlestar Galactica"

A fairly concise list of Colonial Marine Corps ranks can be
surmised from the show, based on those of the United States
Marine Corps (how original!) but there is a 'shortage'
of described enlisted Navy ranks.

i.e. only the (vague) rank of 'Chief' is given
alongside 1st and 2nd Class Petty Officers
('Chief' Tyrol is however described as a 'Senior NCO')

This may be considered strange considering the plot basically
concerns a battleship in space which serves the 'Twelve
Colonies of Kobol'.

Ranks of Sergeant-Major, Sergeant, Corporal, Private
First Class and Private are all mentioned, while crewmen
are only referred to as 'Deckhands' (or 'Knuckledraggers')

Probable enlisted ranks CMC:

1.Sergeant-Major
2.Master-Sergeant
3.Gunnery-Sergeant
4.First-Sergeant
5.Sergeant
6.Corporal
7.PFC
8.Private

Similarly, there are likely a similar rank system
for the navy crew as all crew and officers are in
the same chain of command regardless of duties or
position. The only caveat to this is the titular
(or brevet) rank of 'Commander' which is automatically
given to Battlestar commanders (below Rear Admiral
and above Colonel)

No mention of Generals or other Field ranks for the
CMC are given which is strange considering that it
is a distinct part of the colonial armed forces.
Also, despite Naval terms like Petty Officers and
the existence of an Admiralty from what I can
gather there is no specific mention of a Navy,
instead the Colonial's military acts more like
an Air Force with a Marines section included in
it's overall chain-of-command.

I'm actually uncertain as to what the military
is actually called, OK other than references
to the 'Colonial Fleet'.

Senior Commissioned Officer's ranks roughly follow
that of the modern US Air Force (and most Armies)
and would appear to be the same regardless of
position (i.e. Marines or Fleet):

Colonel, Lieutenant Colonel, Major and Captain

while Junior ranks are based on those used by the Navy:

Lieutenant, Junior Grade Lieutenant and Ensign.

(Marine Ensign?????)

Above Colonel and Commander, the 'flag' ranks given
are Rear and Full Admiral. The position of
'Vice-Admiral' may be assumed while it the actual
number of Admirals is never given.

A 'Colonial Intelligence' section is never mentioned
nor is a security branch outside the CMC either although
both of these are plausible.

Probable enlisted ranks Colonial Fleet
(each position is equivalent
to the same position in the Colonial Marines):
1.Senior Chief Petty Officer
2.Master Chief Petty Officer
3.Chief Petty Officer
4.Petty Officer (1st Class)
5.Petty Officer (2nd Class)
6.Petty Officer (3rd Class)
7.Deckhand
8.Recruit

I should add that despite the continual references to
Ancient Greece and the apparent setting in the ancient
past it seems strange that very modern ranks and officer
/NCO systems are in use. Never mind!

Rough 'explanation' (as far as I am concerned)

Humanity evolves on Earth

Some time later an advanced civilisation develops

Millenia later....

For some reason this civilisation splits into three parts:
Elective Primitives who remain on Earth, an Advanced
Civilisation who,eventually, colonise the planet Kobol

(failed attempts probably include the 12 colonies themselves,
'New Caprica' and 'the algae planet/Jupiter's Eye'
as they all contain some abundance of carbon-based life)

and the quote unquote 'Angels'

Millenia later....

"Summing happens" on Kobol, the 13th Tribe flees to
(an?) Earth and the 12 Colonies are settled

Millenia later....

The Cylons are created (not for the first time),
the 12 Colonies are annhihilated and the remnants
of Humanity, eventually, colonise Earth

Millenia later....

Civilisations are established on Earth

Millenia later....

I write this

The End!
