(Sorry, folks – I had really meant to give you the next section of Darkness Within today. Unfortunately, I’m feeling pretty plague-ridden right now and can’t really give it the degree of attention it deserves, so instead, I’m giving you some non-fic notes on the evolution of the Imperial Military Service.)

One of the minor things that came up with reference to Trope-a-Day: Semper Fi, in a comment on the G+ share of that post, was the traditional interservice brawl; and something mentioned in my answer to that was the Empire’s lack of any Army-equivalent to fight its Marines-equivalent legionaries. And this, I figured, might give rise to some curiosity as to Just How Things Got That Way, both with the lack of one, and which one turned up lacking.

So let’s look back in history a ways.

Specifically, let’s look back to the Union of Empires, which predated the founding of the actual Empire by 42 years or so. Among the many pieces of geopolitical reasoning that went into motivating this particular unification was a military one: one component, the island-bound Empire of Cestia, had – through its sub-polity, the Alatian Kingdom, the finest fleet on the planet. The other, the continental, mountain-bound Moon-Worshipping Empire of Selenaria had the finest army on the planet. If you were to compare the two, respectively, to the British Royal Navy and the Roman legions at their respective heights, you’d be in the right ballparks.

Naturally, the thought of putting the legions of the one onto the ships of the other, overcoming Selenaria’s geographical boundaries and Cestia’s difficulties operating away from water, and thereby conquering the whole damn world put many, many smiles on the faces of both the admirals in Ethring and the generals in Iselené.

These two organizations became the forerunners of the Imperial Navy and the Imperial Legions, respectively.

(Which is not to say those were the only contributions at the time of the Empire’s founding. Of the other founders, the Deeping had its appropriately terrifyin’ warrior-priests, Veranthyr had some of the best light forest scouts in the business, and the Silver Crescent, in particular Leirin and Telírvess, provided more than its share of what I believe are called quote deeply scary-ass axe-wieldin’ motherfuckers unquote, but the two big professional military elements were the above.)

And then, of course, things evolved over time.

The Legions became more of a Marine-like force very quickly, of course, given that amphibious backstory, and that most of the early Empire’s wars did involve close cooperation with the Navy. That in turn, induced something of a fragmentation: one of the first reorganizations split apart the legions that spent most of their time makin’ war offensively from those with a primarily defensive role, the latter of which became the Home Guard, which in turn evolved into a citizen militia with those units serving as its core and cadre.

And time passed, and the Empire expanded, and the Imperial Navy and the Imperial Legions basically borged all the new forces and their units they acquired in the process into their own organizations: sometimes via methods that required great restructuring and retraining, and sometimes by methods as simple as handing out a new Imperial Star to add to their battle standards and informing the Ancyran Devil Dogs that they were now “the Empress’s Hundred-and-Second, the Devil Dogs”.

And more time passed, and military technology were advanced, and portfolios were shuffled, and people invented the notion of an Air Force, which became the Fourth Lord of Admiralty’s purview for the next considerable time, and so it went on…

Up, at least, until the really big post-space-era reorganization. In which several large changes were made over a relatively short period – of which the most major was combining the Imperial Navy and its air forces – both of which had interests in space and relevant specializations – into a single unified force, filling each others’ competence holes, and whose primary business was space. (And, indeed, which lost most of its air-only and wet navy responsibilities, too.) The legacy of that reorg is still visible in their mixed set of traditions, and the quirk in rank structures that explains why an IN O-5 in the Engineering Branch is a Lieutenant Commander, but an O-5 in the Flight Ops branch is a Squadron Leader.

This also made the Imperial Legions even more Marine-y, as it were, because you can’t invade anywhere in space without the IN taking you there – and because it is sheerly impractical to invade planets across interstellar distances by main force, so the sorts of operations they are specialized for are much more in what we might consider the “marine” mode than the “army” mode. The Empire doesn’t have an army suitable for long-term warfare and occupation, because it is firmly of the opinion that it doesn’t need one.

(This also reassures more than a few of their neighbors, which is a nice side-effect.)

And that brings us up to the modern era. So how does it look now?

Well, the man on the street would probably say, all casual-like, that there are two main branches of the Imperial Military Service, the Navy (in SPAAACE!) and the Legions. And on a very casual level, he’d be right. But there are actually eight, under the nine Lords of Admiralty…

The First Lord of the Admiralty, Protector of the Starways, Warden of the Charted Void, Warlord of the Empire (all of which looks so much nicer on a business card than “Secretary of Defense”) is the one that doesn’t have a branch of his own. He commands the central Admiralty itself, (that having won the nomenclatural coin-toss with the General Staff, back in the day), filling both the equivalent posts of the SecDef and the Chairman of the Joint Chiefs, and Core Command, which oversees the Warmains, the appointed supreme-commanders-on-the-spot for each permanent or ad-hoc Theater Command. He’s the most senior military officer, who may be appointed from any of the eight branches, and has full operational command authority.

The Second Lord of the Admiralty is the most senior non-operational officer for the Imperial Navy, as the Third Lord of the Admiralty is for the Imperial Legions, usually both O-14s – Admiral of the Fleet and Captain-General of the Legions, respectively.

The Fourth Lord of the Admiralty is, in the modern era, the O-14 (Lord High Stratarch) in charge of the Stratarchy of Military Unification. That, in turn, amounts to the “department of misc” – in the final reorganization that created the IN and IL in their modern forms, this Stratarchy acquired all the military functions that didn’t fit in either of them: the Empire’s remaining specialized air forces and wet navy forces, for example, along with a variety of other functions too specialized to fit well in the IN and IL, along with some other oddity functions like “privateer liaison”, and so forth.

And then there are the stratarchies created by further modern-era additions.

The Fifth Lord of the Admiralty commands the Stratarchy of Data Warfare, which is responsible for making the Empire’s enemies deeply regret that they ever plugged anything into the extranet, and quite possibly that they ever invented electronics.

The Sixth Lord of the Admiralty commands the Stratarchy of Indirection and Subtlety, which is in charge of assassinations, sabotage, economic warfare, ecological warfare, financial warfare, and pretty much everything else from the big book of dirty tricks that doesn’t fall under the purview of…

The Seventh Lord of the Admiralty, whose Stratarchy of Warrior Philosophy houses war-lawyers and military memeticists whose function is to use misinformation, meme-attacks, psychological warfare, cultural propaganda, and outright toxic memes to find the strands holding an enemy’s morale, military, economy, society, religion, culture, etc., etc., together and basically unravel them. When your plans for a nice little war are rudely interrupted by a multi-way civil war breaking out at home, it’s the Seventh Lord who strokes his mustache and indulges in evil laughter.

The Eighth Lord of the Admiralty commands the Stratarchy of Military Support and Logistics, which is exactly what it says on the tin, and ensures that everyone else has exactly what they need when they need it, even – or perhaps especially – if it hadn’t occurred to them to ask for it yet.

And the Ninth Lord of the Admiralty, the Commandant of the Guard, commands the Home Guard (remember them?) in maintaining defensive garrisons, fortifications, and facilities and training services for the citizen militia.
