Thyatian Military Deployments (notional).

by James Ruhland

N.B. for this I'm using neither the terminology of "canon" nor true "Byzantine" terminology, but rather the terminology I've used so far in posting my (still under construction and modification) ThyMil Variant. Also, no specific date on this, so it could be whenever.

Plus various auxiliary (colonial) formations of varying size and strengths, attached. Note that even for the above forces the deployment given is basing/garrisoning: these are mobile forces, not fixed forces. These are however the locations of their military lands (the Stratiotika Ktemata).

I understand that you are still working on this stuff, but are you comparing population figures with army strengths, and available budgets with the cost of all these forces? Have you already allocated numbers to these units at any rate?

I'm comparing population figures, and have a rough idea of the budget, and the cost (rough only, though). The unit strengths are all worked out, at least for the ones given, though ultimately I plan on dealing with the structure (differentiating the Tagmatic units for example).

I'm keeping the units in the spirit of the "professionalised, regular military" assumption of the PWA War Mach stuff, but also "Byzantinising" it to a degree. How?

Well, for example, the aforementioned Stratiotikon Ktema: troops are partially paid in cash, but also "in kind" through the allotment of military lands, and they are "semi-active". By which I mean that, though, for example, a Thematic Exercitus has a full strength of 2,000, this full-strength is only mobilised completely in wartime. Peacetime strength is 1,100, with the rest on reserve (rotated through the year for training). Mobilisation for these units are quick, a la the Israeli model, and the mid-Byzantine (9th-11th centuries) model.

Similarly, the "Reserve" Exerciti have a fully mobilised strength of 2,000 but active peacetime strength of 560. The Defenders Exerciti are uniformly reserve units (there are also Militia Exerciti below them).

Total strength of the forces I've detailed so far are as follows:

                        Guard Forces: 15,200/15,200
                        Retebius Air Fleet: 1,200/1,200 (KotA?)
                        Thematic Divisions: 22,000/40,000
                        Naval Forces: 20,000/29,200
                        Reserve Divisions: 5,600/100,000

                   Grand Total: 64,000/185,600

The first number (before the slash) represents the "active" standing forces at any given time. The number following the slash represents reserve forces. Note that the first number is a fixed value (should stay at 64,000) while the second number will change some as I still have to detail some militia units (notably the Deme militias). This represents a great improvement over the notional "full strength" Thyatian armies described in the PWAs (122,750 personnel, 4% of population) and even the post-WotI nominal Thyatian strengths (70,510). It is slightly over 2% of the PWA population (3,001,000), and slightly under 2% of my notional population (3,420,000). ("KotA" represents "Knights of the Air" which I may detail as a aerial reserve force).

A note on naval nomenclature: not so happy with that so far ("1st Fleet" and "Marine Assault Force" and the like), I've never really found a good "Byzantine" name, for individualised naval forces (I know what to call the commanders: Megas Drungarios, Drungarios, etc).

Further note on nomenclature: for familiarity I have been using "Roman" names of units in what I've posted for general use. The "real" names are different. The basic unit of course is the company, called a Bandon (literally "Banner", thus identical to the basic unit of the War Mac militaries described in X10 and the PWAs). Above that is a "Battalion" level unit which for convenience's sake I've refereed to as a Cohort, but which should be known as a Moira. The Exercitus is the Divisional name I've used since Legion was used for Darokin, but even so the proper name is Turma.

The Bandon is commanded by a Comes, or Count, who has a deputy known as a Illarch, and there are several ranks of sub-commanders as well. The Moira is commanded by a Moirarch, and the Turma by a Turmarch. Armies are commanded by Strategoi, with deputy commanders known as Hypostrageoi.

There is a whole separate ranking system for the Tagmata (Guard units), and it can all get confusing very fast, so I've vastly simplified everything, to the extent of (on my website) using English or roman ranks, but I'm going to convert those. IMO, the same thing that made me draw back from using the "proper" nomenclature is/should be the same thing that will impel me to ultimately use it: the exotic nature makes it distinctive.

Now, as far as strengths: I feel I've somewhat pruned units down as small as I'd like. For tactical reasons each division should have 18 companies (based on tactical deployment suggestions in Byzantine military manuals).

More on budgetary matters: perhaps that is what I should do next. Post the fiscal outlook, tax receipts from the land tax, hearth tax, commercial, and other sources of income. That will give some idea of what we're dealing with, and following that we'll see if my "ideal" force is possible, or if further compromises need to be made. Btw, I also have a clear idea of what pay scales will be for both the army and the civil service.
