I'd like to think that the Royal Guards have a plebian counterpart that patrols the region and keeps most of the riff-raff out of the civilized areas.
Some concepts I've thought up forthe Royal Military...
Royal Guards are the elite. Handpicked out of the rank and file military for duty in Canterlot and used for palace duties. They rotate out between guarding the Royal Sisters, standing watch on the palace grounds and various ceremonial duties around Canterlot. Royal Guards do not typically display their rank, so as to present a uniform appearance.
Some random concepts I had on the
Royal Army and
Royal Air Corps (EP's man the Army, Pegasi join the Air Corps, Unicrons do administrative duties and other chores, but can also join the Army with a waiver):
Secure messenger service between units is done via the
Royal Messenger Corps, a subdivision of the Royal Guards. Comprised strictly of Pegasi, they fly small packages, letters and such from place to place. They usually fly solo. Lightly armored, using a flexible chain or scale mail, as opposed to plate.
There are Axiliary functions in the Army and Royal Guards that are best fit by specialized troops. Usually, these positions are filled by Unicorns. Record-keeping, Engineers, Finance, Medical teams, and so on. These are usually non-combat positions, and are designed to support the warfighter, so to keep the troops at maximum eficiency. You can typically find these specalized troops in cities and the like; Ponyville is too small to have an Auxiliary Corps detachment, for example.
Royal Army troops are lightly-armed (padded armor and bits of chain-mail, a spear for a weapon) EP's, deployed in 30-pony platoons (or
Turma to borrow the Roman term) led by three veteran soldiers; one of these lead the platoon, the other two were deputies. Each veteran commands ten troops (a Squad), so the total platoon strength is 33 ponies. The Veteran of each Squad has more chain-mail, but is otherwise light armored as well. A single platoon is usually assigned to cover the hinterlands surrounding a town. More assigned as needed for larger areas. They tend to stay out of sight,
Enlisted ranks in the Royal Military: Recruit, Private, Corporal, Sergeant, Senior Sergeant, Master Sergeant, Sergeant Major. Sergeant Major, when plural, is Sergeant
s Major. DO. NOT. SCREW. THIS. UP. Enlisted rank is denoted by the number of cheverons and rockers clasped to the shoulder-loops of the armor. Recruits are denoted by having no rank insignia at all, after that, each rank gains a cheveron, (up to three), followed by rockers. Thus, a Sergeant Major has three cheverons and three rockers.
Offier Ranks in the Royal Military: Officer-Cadet, Fourth-Rank Lieutenant, Third-Rank Lieutenant, Second-Rank Lieutenant, First-Rank Lieutenant, Captain, Major, General. An officer who hold a Lieutenant rank is usually referred to as "[Title] First Rank [Name]", and the Lieutenant suffix is dropped except for extreme formality, or written orders. Officer rank insignia for Lieutenants is denoted by small stars set on a small black plate on the shoulder of the armor. A fourth-rank has one, a first has four. Captains have a single large star bouded by an enamel square, a Major has two in an enamel rectangle, and a General has three bounded together in an enamel triangle. Officer-Cadets have only a blank black square, gaining a small star upon completion of their officers training course.
Example, standard address - Messenger First-Rank Firebird, Auxiliary Third-Rank Landesknecht
Informal address: Messenger Firebird or simple "El-tee", Aux Third or Aux "Land".
Fomral address: Messenger First-Rank Lieutenant Firebird, Auxiliary Third-Rank Lieutenant Landsknecht.
The Royal Air Corps is divided up into
Wings. Each Wing is comprised of three
Flights, each with ten Pegasi, under command of a Flight Leader, typically a Senior Sergeant or Fourth-Rank. A Flight will typically be assigned an area to patrol, spotting threats fro the air and relaying these finding to the Platoon or Earth Ponies on teh ground nearest the threat. Thus, a Flight and a Platoon work in concert to ensure safety to a geographical area.
The Royal Air Corps has a strong sense of tradition, borne out by long centuries-worth of military tradition amongst the Pegasi. A large number of Royal Guards are pulled out from the Air Corps as a result, and it is commonly viewed as the more professional force than the Army, much to the Army's chagrin.
