Generals command large units brigade-size and larger and hold high-echelon staff command positions. Field marshals lead full armies, and above them is the Marshal of the Armies of the Senate and People of the Republic of Free Races, serving as part of Joint Command.
Promotion to brigadier general requires a doctorate in military science.
Field officers command units of battalion size up to brigade size or serve in high-level staff roles.
Promotion to major requires a master's degree in military science.
Company officers command units the size of platoon up to a company or serve in staff roles.
Professional officers hold a bachelor's degree in military science and start as full lieutenants. Reserve officers or conscripts complete a training period and start as 2nd lieutenants. Promotion to field officers requires a degree in military science, though NCO and officer training gives study credit worth the first year.
Cadets are trained in the various campuses of the National Defence College, where anyone with the qualifications and aptitude can become a professional officer in the Republic Military.
The army study program focuses on large-scale ground warfare and its support.
Cadets are ranked not only by their class, but also by an internal ranking system: Corporals lead dorm sections of cadets, sergeants lead full dorms, and each campus has one master cadet to internally lead the cadets and represent them for the faculty.
The only rank restriction is that only a 4th-year cadet can be master cadet.
Cadets are treated as OF-1 by the other ranks.
The four-year cadet program is counted as a bachelor's degree in military science. A master's degree is required when promoting from company officers to field officers. Any holder of a bachelor degree can attain a master's degree in parallel with their military service, and further on apply for a doctorate in the field.
Generals and officers in general staff are required to hold a doctorate in military science.
Students are temporary ranks used while conscripts or enlistees are trained for higher ranks.
NCO students are trained in two phases: rifleman corporal training, where the basics of squad leadership and squad weapons and tools are trained; specialized training where the NCO student is trained in whatever specialization he is found most suitable for. Best first phase students are assigned to officer training. NCO students are equal to OR-3.
Officer students are trained in the basics of platoon command and equipment and are promoted to officer cadets for specialization. Officer students are equal to OR-4 and officer cadets are equal to OR-5.
Warrant officers hold senior NCO positions in larger units or command their own sections. Specialist WOs are given technical task-oriented command positions.
NCOs command squads of soldiers or serve as assistants in larger units' staffs.
Rank and file constitutes the bulk of personnel within the military, with soldiers trained for specific tasks relating to combat or the support thereof. Most serving soldiers are conscripts who enter the reserve after their service period, while enlistees make the standing army, though they rotate between active service, training and reserves during different tours as needed. An enlistee can serve multiple consecutive tours in active service, if they so request.
Military priests offer spiritual services in a multitude of faiths and denominations, with officer-grade priests being ordained ministry in a church of faith. In local-recruitment brigades priests are usually of the faiths encountered in the brigades' areas of recruitment. Military chaplains also have training in basic psychology and social studies, functioning as unit councilors in cases where the need of a fully trained psychiatrist is either not needed or the need for one has not yet been established. Conscript pastors have started vocational training in mental health care or as a socionom, but they are not ordained into priesthood. In lieu of their social profession, they assist officer-grade military pastors in their duties.
Military court specialists are employed in the Judge Advocate General Corps, serving primarily as legal advisors to the command to which they are assigned. In this function, they can also serve as the personal legal advisor to their commander. Their advice may cover a wide range of issues dealing with administrative law, government contracting, civilian and military personnel law, law of war and international relations, environmental law, etc. They also serve as prosecutors for the military when conducting courts-martial. They are charged with both the defense and prosecution of military law as provided in the Articles of Military Justice. Highly experienced officers of the JAG Corps often serve as military judges in courts-martial and courts of inquiry.
NCO-graded court officials serve as assistants and trainees in the military court, while officers serve as judges and advocates.
For the m/13 system I've revamped the presentation of the rank chart; retouched instances where the Republic heraldic eagle is used; redesigned the cap badge. I'm also infodumping on military doctrine relevant to the arms and rank grades.
