Consistentish Commissioned Ranks used
in "Battleship Delusions"
i.e. the 2003-onwards Ronald D.Moore version of
"Battlestar Galactica"*

Admiral/Admiral of the Fleet
Vice-Admiral (i.e. Helena Cain)
Rear-Admiral (William Adama post-Cain?)
Colonel (i.e. Saul "I'm a drunken Cylon" Tigh)
Lieutenant-Colonel (Robert Fisk, and other
dumb dead fraks)
Major (i.e. Lee 'Apollo' Adama)
Captain (as in 'Helo','Starbuck' and
'Apollo' before he was promoted)
Lieutenant/Full Lieutenant (Sharon 'Boomer' Valeri)
Junior Lieutenant/Ensign [these ranks
are mentioned but the insignia are all the same]
(Sharon 'Athena' Agethon and loads of other dumb fraks)

Fraks who "Command" battlestars but who aren't Admirals
are always 'Commanders'. They outrank Colonels. Colonels
and Lieutenant Colonels (same thing?)are always drunken
fraks, drunken Cylon fraks, corrupt fraks or paranoid fraks.

Commissions seem to be based on completing flight training
as part of the officer training school, or are given to serving
non-comms (i.e. PO2 Dualla married Lee "I'm not at all like my
Dad" Adama and was duly promoted to Junior Lieutenant). It is
debatable but probable that Officers in the Colonial Marine
Corps also undertook basic flight training. Full Lieutenants
are officers with greater flight experience.

The military in "Battleship Delusions" is pretty much
based on the United States Marine Corps. There are no
separate chains of command for different branches of the
service (so far as I can tell). And they're not trained
in defending themselves from jars of coffee that try to
attack them. Or are told what a hymen is. Do Cylons have
hymens? Frak knows!

*Actually, in terms of consistency the following
system for the Colonal Military as a whole/chain
of command would likely be as follows (I've
made 'Sergeant' a Commissioned Rank to account
for this and included all Commissioned Ranks
described and presumed i.e. shown on uniform
tags, described by the creators and shown in
shots):
President of the Twelve Colonies of Kobol
Vice-President etc
Minister of Defence
Fleet Admirals
Admiral
Vice-Admiral
Rear-Admiral
Commander
Colonel
Lt-Col.
Major
Captain
Lieutenant
Junior Lieutenant
Ensign
Sergeant
(some dumb dead Frak called
'Chuckles' was a Sergeant,
at least according to his
flight uniform. Warrant
Officer makes more sense.
Battleship Delusions
doesn't)
Cadet

Deckhands:
Master Chief Specialist
Senior etc
Chief Specialist
Sp1
Sp2
Sp3
Deckhand/Recruit

Marines:
Master Corporal
Senior etc
Chief etc
Staff Corporal
Cpl
Lance etc
PFC/Private
