Personnel and Ranks

[SushiKnight]

Here's a brief breakdown of the organisation of the Republic Army:
Regular Army:

Type of Unit	Composition	Led By
Section	9 Troops	Sergeant*
Platoon	4 Sections	Lieutenant
Company	4 Platoons	Captain
Batallion	4 Companies	Major
Regiment	4 Batallions	Lieutenant Colonel or Colonel/Jedi Padawan Commander**
Legion/Brigade	4 Regiments	Brigadier-General/Senior Clone Commander/Jedi Knight**
Corps	4 Legions/Brigades	General of any rank/Clone Marshall Commander/Jedi Knight**
Sector Army	4 Corps	General of any rank or Surface Marshall/Jedi Master**
Systems Army	2 Sectors Army	High Marshall/Jedi Master (Council Member)**
Grand Army	2 Systems Army + additional (including Special Forces)	Supreme Chancellor and Grand Marshall/Jedi Council**

Special Forces:

Type of Unit	Composition	Led By
Squad	4 troops	Sergeant
Troop	4 Squads	n/a***
Company	5 Troops	n/a***
Commando Group	5 Companies	General (Brigadier-, Major-, or Lieutenant-General)/Jedi Knight
Special Operations Brigade (SO BDE)	10 Commando Groups	General (General or High-General)/Jedi Master

SO BDE fits into the GAR scheme directly under the Commander-in-Chief, and outside of the Systems Army command structure, so that the commando units can be sent wherever they are needed immediately, without transferring their command to a new Systems Army.


Footnotes:
* Non-commissioned Officer
** Jedi only command Clone troops. Non-clones are never commanded by Jedi, who exist outside of the true military command structure. They may, however, work with Jedi under joint commands.
*** Not Applicable. Commando squads are organised into Troops and Companies for ease of bookkeeping. Each Squad is commanded by it's Sergeant. Note that "Sergeant" is the minimum rank needed to command a squad. Indivual squad leaders might be promoted to higher ranks to reward strong performance.

I'll post a rank progression next.

Private: Some specialist army units use alternative ranks equivalent to Private: Trooper in armoured units; Gunner in artillery; Signalman in signals, etc.

Most Republic ground forces wear armour, and thus are referred to as Troopers. Commando is appropriate for Special Forces units.

A Private makes up the bulk of any ground force.


Lance Corporal: In artillery units a Lance Corporal is known as a Lance Bombardier. A Lance is usually second in command of a fire team. A Lance Corporal is referred to as "Corporal" except in the most formal of circumstances. May be referred to as a "Lance" in the third person, i.e. "Corporal Fon is my Lance."


Corporal: In artillery units a Corporal is known as a Bombardier. A Corporal leads a fire team.


Sergeant: A Sergeant leads a squad or section. In larger sections, this will be further subdevided into fire teams. In Clone units, a Sergant is identified with green fletching. In specialized units, however, they will carry unit markings.


Second Lieutenant: The 2nd Lieutenant is the least senior of the commissioned ranks. This is the rank you need to attain to be in command of a Platoon. A Second (or First) Lieutenant is referred to simply as "Lieutenant" except in the most formal of circumstances. Clone Lieutenants typically have blue armour fletching. Though in specialized units, they wear unit colours.


First Lieutenant: Basically the same as above, but at a higher pay-grade. Clone Units only have "Lieutenants". They aren't sub-devided to seniority.


Captain: A Captain is the least senior rank needed to command a company. Clone captains typically have red fletching, except, of course, in specialized units.


Major: Officer in charge of a Batallion. Clone units do have this rank, but I have no information on armour fletching at this time.


Lieutenant Colonel/Colonel: Officer in charge of a Regiment. Lieutenant Colonels are referred to as "Colonel". Clone Regiments are instead commanded by a Padawan-Commander.


I'll just list the further ranks in increasing levels of seniority because I'm tired and want to go to bed. I'll mod this later.


Brigadier-General: Officer in charge of a Brigade. Clone units are instead called "Legions" and are commanded by a Senior Clone Commander. Clone Commanders feature yellow armour fletching. They are also allowed to wear ARC armour and have individual names which are used outside of their squads*.


Major-General/Lieutenant-General/General/High-General: Officer in charge of a Corps (or higher). Marshall-Commander is the equivilant Clone rank. They also feature yellow armour fletching and ARC armour modifications.


Surface Marshall: Officer in charge of a Sector Army. Clone units are lead by a Jedi Master.


High Marshall: Officer in charge of a Systems Army. Led by a High Jedi General (Council Member) in Clone Units.


Grand Marshall: Commander-in-Chief of the Army.


Notes:
All General ranks, besides Brigadier are referred to as "General". Brigadier-Generals are referred to as "Brigadier". Surface Marshalls are "Marshall". Grand Marshall is, however, referred to with full rank.

You never heard of Thrawn being called "Admiral" did you? (Allright, you smart-ass. I know what you are thinking: "Except when he -was- an Admiral." Yeahyeahyeah. You know what I meant.)

Footnotes:
*Other clones might have individual nicknames, but these are not used outside of the Squad/Section environment. Clone Commanders, on the other hand, have earned the right to be called by their name, and often select one that has a personal meaning to them. A good example of this is Commander Gree, Yoda's Clone Commander on Kashyyyk during the Clone Wars. Gree is an obscure alien language, showing Commander Gree's love of obscure languages. Oddball is another good example.

Could I just become a private?
