Generic Military

More to come.

Structure
The military operates in two main groups, the Common Group and the Technical Group. The Technical Group usually has educational requirements at one level higher than the Common Group, and the pay is also one grade higher than the equivalent Common rank, but ironically, except for the case of Privates where it is reversed, Technical Group members always rank below their equivalent Common counterparts.

Privates
Privates are soldiers with no Leadership responsibility, who specialize in certain fields and for certain assignments and tasks that they are responsible for.

Common Privates
The above sentence largely emphasizes the common Privates. They work on 5 year contracts and cannot re-enlist if they reach their fifth year and remain members of this personnel group at the end of the fifth year, unless they re-enlist after obtaining access to a different personnel group through other means (such as Corps Cadet). All Privates can simply be referred to as "Private".
 * Private 3rd Class (Called a "recruit") - A single downward pointing chevron
 * Private 2nd Class - (Called a "Trooper" if terrestrial, or "Sailor" if Naval) Two downward facing chevrons, one below the other
 * Private 1st Class - (Not designated differently from 2nd Class) Three downward facing chevrons, all three consecutively below each other
 * Master Private - Three downward facing chevrons, all three consecutively below each other, with a symbol above (the Symbol being the symbol of the branch the Private belongs to, this rank is usually given to a Private upon accomplishment of a private-contract, without having advanced into another personnel group, and it is extremely rare to find a Private carrying this rank in service, but it does sometimes happen as a means of reward, in which case it is usually short-lived, with the Private being offered to move-up).

Technical Privates
Technical Privates are called "Specialists", and work under the same contractual terms as Common Privates. Specialists are paid better than Privates of equivalent Rank, by one full rating, meaning a Master Technical Private makes as much money as a Junior Petty Officer 3rd Class, however, most specialists have real-world experience in a specific field, or even formal training and education.
 * Technical Private 3rd Class - A single straight horizontal line
 * Technical Private 2nd Class - Two straight horizontal lines, one below the other.
 * Technical Private 1st Class - Three straight horizontal lines, all three consecutively below each other.
 * Master Technical Private - Three straight horizontal lines, all three consecutively below each other.

Junior Petty Officer
Junior Petty Officers are typically those who Graduate from the Corps Cadet having taken a short education or the the Officer's Academy after a brief time there. Junior Petty Officers do not necessarily have any real leadership responsibilities, as they are considered to be management-in-training, and the rank is frequently given simply to extend the contract on a good soldier, as Junior Petty Officers are usually contracted for 20 years (including time spent).

Common Junior Petty Officer
Common Junior Petty Officers are almost always those who are sent from the military to the Military Academy, for, usually, 6 months, meaning they usually transition from being Privates.
 * Junior Petty Officer 3rd Class - A single upward pointing chevron (referred to as an "Command-Cadette")
 * Junior Petty Officer 2nd Class - Two upward facing chevrons, one above the other (usually referred to as a "Lance-Corporal")
 * Junior Petty Officer 1st Class - Three upward facing chevrons, all three consecutively above each other (usually referred to as a "Corporal")
 * Chief Junior Petty Officer - Three upward facing chevrons, all three consecutively above each other with a symbol below the lowest chevron (usually referred to as a "Master corporal").

Technical Junior Petty Officer
Technical Junior Petty Officers differ from Common Junior Petty Officers in the same way that Specialists differ from Common Privates, by being one rating higher in pay but also by having higher degree-requirements across the board. Unlike Common Junior Petty Officers, the job of being a Technical Junior Petty Officer is definitely a one-way track to leadership positions.
 * Technical Junior Petty Officer 3rd Class - A single upward pointing half-chevron
 * Technical Junior Petty Officer 2nd Class - Two upward facing half-chevrons, one above the other
 * Technical Junior Petty Officer 1st Class - Three upward facing half-chevrons, all three consecutively above each other
 * Chief Technical Junior Petty Officer - Three upward facing half-chevrons, all three consecutively above each other with a symbol below the lowest half-chevron

Senior Petty Officer
Senior Petty Officers are the real middle-management of the Military, supervising the individual departments down the chain. While usually working for an higher ranking Officer, the Senior Petty Officers are charged with knowing their department like the back of their hand, while the higher ranking officer's job is to remain appraised of the rest of the military - this being two-sides of the leadership coin.

Common Senior Petty Officers
Common Senior Petty Officers are most frequently former Common Junior Petty Officers who are sent to the Academy to train for their new rank and status, usually for some time. It is somewhat less common to graduate from a school's Corps Cadette as a Common Senior Petty Officer, but it can happen.
 * Senior Petty Officer 3rd Class - Three upward facing chevrons, all three consecutively above each other and one downward facing bow below the lowest chevron (usually called a "Sergeant" or sergeant 3rd class)
 * Senior Petty Officer 2nd Class - Three upward facing chevrons, all three consecutively above each other and two downward facing bows, consecutively below each other, below the lowest chevron (in infantry units, usually called a "Gunnery Sergeant", and otherwise typically called a "Line Sergeant" or sergeant 2nd class)
 * Senior Petty Officer 1st Class - Three upward facing chevrons, all three consecutively above each other and three downward facing bows, consecutively below each other, below the lowest chevron (usually called a "Staff-Sergeant", and work directly under the unit leadership as 2nd in command)
 * Chief Senior Petty Officer - Three upward facing chevrons, all three consecutively above each other and three downward facing bows, consecutively below each other, below the lowest chevron and a symbol in the hollow between the highest bow and the lowest chevron (usually called a "Master-Sergeant", and often work as advisors and assistants to the commander of a Company or Squadron).

Technical Senior Petty Officers
Technical Senior Petty Officers and Common Senior Petty Officers, once more, follow the exact same pattern of differences as the Technical Privates did from the Common Private, and similarly as with the Common Senior Petty Officers, only a little less than half ever advance out of the Personnel Group. Technical Senior Petty Officers are consecutively referred to as "Technical Sergeants".
 * Technical Senior Petty Officer 3rd Class - Three upward facing half-chevrons, all three consecutively above each other and one straight horizontal line, a small distance below the lowest half-chevron.
 * Technical Senior Petty Officer 2nd Class - Three upward facing half-chevrons, all three consecutively above each other and two straight horizontal lines, consecutively below each other, a small distance below the lowest half-chevron.
 * Technical Senior Petty Officer 1st Class - Three upward facing half-chevrons, all three consecutively above each other and three straight horizontal lines, consecutively below each other, a small distance below the lowest half-chevron.
 * Technical Chief Senior Petty Officer - Three upward facing half-chevrons, all three straight horizontal lines, consecutively below each other, a small distance below the lowest half-chevron and a symbol in the hollow between the highest line and the lowest half-chevron.

Junior Officers
Commonly just referred to as Junior Officers, this personnel group traditionally comes with considerable requirements, including endorsements from educational facilities, and prior military experience, or a long-term commitment to the Military Academy.
 * Junior Officers are the other face of the leadership-coin, being generally focused on the rest of the military, as opposed to focusing on knowing their own assignment and unit, relying on a subordinate Senior Petty Officer to remain in the know of these matters.
 * There is a distinctive leap in responsibilities and status from the Petty Officer Group to the Junior Officer Group, with "Common" Junior Officers being called "Administrative Junior Officers", and their counterparts remaining Technical Junior Officers. In a society where Nobility is non-existent, a typical requirement to become a Junior Officer would be higher education, in the case of a meritocracy, or even a monetary contribution to the Military (purchasing a Commission) in an oligarchy.

Administrative Junior Officers
The Administrative Junior Officers are trained specifically to understand the bureaucracy, chain-of-command and general function of every aspect of the military, meaning they have a much easier time communicating with, and understanding how other units operate than their lessors - but they generally tend to be much less specifically trained than a lower-ranking Petty Officer, and typically entirely lack a full understanding of the units they personally administrate, but as they advance, they grow into this understanding.
 * Junior Administrative Officer 3rd Class - A single bar (referred to as "Ensign" or as "Cornet" in the Cavalry, works as an Adjutant to another Junior Officer, and is essentially "apprenticed" - Sometimes derogatorily called a "Butter Bar").
 * Junior Administrative Officer 2nd Class - Two bars, side-by-side (Referred to as a "Yeoman", commands a Sub-Unit)
 * Junior Administrative Officer 1st Class - Three bars, side-by-side (referred to as a 2nd Lieutenant - typically an Adjutant to a 1st Lieutenant).
 * Chief Junior Administrative Officer - Three bars, side-by-side with a line drawn through the middle, binding all three bars together as if speared by it (referred to as a 1st Lieutenant, but typically serves as a Captain, as they are the lowest rank to typically have command of a unit capable of holding sub-units, meaning any vessels or installations fall under the command of the 1st Lieutenant).

Junior Technical Officer
Differing from their administrative counterparts in the same way as previous examples of Technical officers have from their common counterparts, Junior Technical Officer is a personnel group that extremely few advance from (one in ten). Consecutively referred to as "Technical Officers".
 * Junior Technical Officer 3rd Class - A single hollow circle
 * Junior Technical Officer 2nd Class - Two hollow circles, side-by-side
 * Junior Technical Officer 1st Class - Three hollow circles, side-by-side
 * Chief Junior Technical Officer - Three hollow circles, side-by-side with a line drawn through the middle, binding all three circles together as if speared by it.

Senior Officers
Senior Officers are promoted from the ranks of Junior Officers, with promotion to the first rank of Senior Officer almost guaranteed with seniority, but the remaining ranks being extremely competitive. Senior Officers are not typically involved in any huge decision making on their own part, but often supervises the decision making of those below them in rank, ensuring that mistakes aren't made.

Administrative Senior Officers
The first rank of Administrative Senior Officer usually commands a unit equivalent in size to a Company, and promotion to this rank, from Administrative Junior Officer, is almost guaranteed, but many careers end here. At this point, the Officer becomes less of a leader, and more of a supervisor and bureaucrat, and all the experience the Junior Officer has built up from working in a sub-unit, is suddenly not necessarily applicable to going forward, often resulting in transitional issues.
 * Senior Administrative Officer 3rd Class - A single diamond (referred to as a Master-Chief, the Master-Chief either serves as a commander for a specialized sub-unit, or as Adjutant to another Senior Officer, similarly to how a Junior Administrative Officer 3rd Class serves as Adjutant to another Junior Officer).
 * Senior Administrative Officer 2nd Class - Two diamonds, side-by-side (referred to as a "Major" in a terrestrial unit, or "Commandant" in the Navy).
 * Senior Administrative Officer 1st Class - Three diamonds, side-by-side (referred to as a "Colonel" in terrestrial units or "Commodore" if naval).
 * Chief Senior Administrative Officer - Three diamonds, side-by-side with a line running through all three diamonds, binding them together, as if speared (referred to as "Brigadier" if a Terrestrial unit commander, or "Flotillier" if Naval)

Technical Senior Officers
Senior Technical Officers do not differ from the remainder of their kind purely because Senior Administrative Officers do not require a higher education than Junior Administrative Officers, meaning the same educational requirements are in effect for both Senior and Junior Technical Officers. There are extremely few Senior Technical Officers, and it is impossible to advance out of this personnel group without becoming an Administrative Officer instead, which is extremely unlikely.
 * Senior Technical Officer 3rd Class - A single circle with an X in it
 * Senior Technical Officer 2nd Class - Two circles with X symbols in them, side-by-side
 * Senior Technical Officer 1st Class - Three circles with X symbols in them, side-by-side
 * Chief Senior Technical Officer - Three circles with X symbols in them, side-by-side with a line running through all three circles, binding them together, as if speared

Flag Officers
Flag Officers are Generals and Admirals, marked by Stars as their insignia symbols and coming in three classes, referred to as (respectively), rear-, vice- and Command General or Admiral with the Chief-General/Admiral being the Supreme Commander himself.

Other Ranks
Some Ranks exist outside of the common rank-structure, but are typically equivalent to that of Junior Officer and are to be assumed so unless otherwise noted. Special Ranks always outrank those they equal in rank, but do not rank equal or higher than the next level, in case of Chief/Master level.

Military Police
Military Police Officers can be referred to as "Constable", except when in the Junior Officer Personnel Group or higher. All Military Police Officers (as the name indicates) are at least Junior Petty Officers.
 * Considered as technical officers, regardless of official rank in their respective personnel group, they always outrank all members of their equivalent personnel groups.
 * Upon reaching the Junior Officer Personnel Group, Military Police Officers are referred to as "[insert short-hand name for equivalent rank in the administrative column]-Constable", for instance, a Military Police Officer holding rank equivalent to a 2nd Lieutenant would be called "Lieutenant-Constable".
 * The Master-Chief equivalent is just a "Chief-Constable".
 * Upon reaching the Senior Officer personnel group, the Constable is replaced by Provost. There is only one Provost-General, who is the only Military Police Officer who exists in the Flag-Officer Personnel Group.

Special Warfare Operators
Special Warfare Operators, referred to simply as "Operators" (regardless of rank), following the same rank-protocol as Military Police Officers, except that they are always outranked by Military Police of equivalent Personnel Group, and the highest achievable rank for a Special Warfare Operator is the Master-Chief equivalent, referred to simply as "Master-Chief" and never as "Operators", being the only person in a unit of Operators who is actually called by Rank.

Temporary Ranks
Some ranks are temporary, and can be addressed as such, but this is commonly only done in writing.

Captain
While not temporary in the same sense as the other ranks found here, the commander of any military vessel or installation is referred to as "[insert rank]-Captain".
 * A soldier who has a vessel(s) under their command, is temporarily promoted to "[insert rank]-Captain", but if not personally steering the vessel(s) in question, the Captain appoints (or there is a protocol in place that selects) a commander for the vessel(s) in question.
 * Captain also applies to the Commander of any installation, even temporary camps, exactly as if the installation was a vessel.
 * In many ways, a Captain is the De-Jure commander of a given installation or vessel, whereas a Commander is the de-facto commander of any such.

Commander
Any person can be given temporary control of any unit designation without receiving any kind of promotion. This is called "Command Appointment", and the appointed is "Commander [insert name of unit designation]".
 * While considered rude, a soldier who does not know, remember or care to speak the rank of his actual superior can always say "Commander" - though this is not considered rude in the field, where it is generally considered prudent to disclose as little personal information as possible - including ranks and names.
 * The commander of a vessel, appointed by means of protocol or by the Captain of the vessels, is referred to as "[insert rank]-Commander", as long as that person remains in control of the vessel, by appointment.

Adjutant
An Adjutant is second-in-command of some sort of unit, though the use of the word is mainly in regards to a proper Command (being the kind of unit that requires a Junior Officer at least), the terminology is used in all unit-regimes.
 * The 2nd-in-command is "Adjutant-[insert-rank]" or in much more formal settings "Adjutant-[unit designation]".

Brevited Rank
Being promoted by means of Brevit, means that the promotion is temporary, but assigned for no specific reason, usually with no specific expiration date on the temporary promotion - though it is often affiliated with a specific position, and the Brevit would be lost if the position was.

Field Promotions
There is an automatic field-promotion scheme in place, where the highest rank (or highest seniority in case of multiple same ranks) is automatically field-promoted to the appropriate rank necessary to take the place of a higher ranking soldier who is no longer present to fulfill their duties, with it being unknown when this superior will return/be replaced.
 * In situations where the unit commander simply temporarily departs, having left instructions about their return, the title of Commander is instead imparted upon the person next in line (or person of the Unit Commander's choice) to assume the duties of leadership.
