State of the Duranium Legion in the Year 4100As alluded to above, the economic situation of the Duranium Legion in Y4100 was not very good, frankly the only reason not to use the word “abysmal” would be a concern about understating matters. Aside from the limited reserves stockpiled on Duratus proper, only 800 tons of duranium were estimated to remain in the Solar system outside of the minimally accessible deposits on Venus, and even worse only 81 tons of gallicite could be located apart from deposits on the comet 2017 MB7 which was comfortably out of range of any Legion mining operation. Slightly less dire was the situation for uridium, the minor component for precious warship maintenance supplies, of which over 1,300 tons remained to be mined out at the Uridium Valley Mining Site on Eukrate. The fact that only 225 tons of corundium remained in the entire system was surprisingly of no concern, given the abundance of mining complexes sitting empty on Duratus.
The dire Solar resource situation facing the Legion in Y4100. While on first glance the budding Legion economist might be tempted to seek relief from the abundant mineral deposits of Hale-Bopp, 2017 MB7 or C/2017 K2, in reality these comets were so distant from Duratus that no mining venture would possibly be productive in enough time to solve the crisis. On the positive side of things, there would surely be no shortage of tritanium. While the basic needs of Legion citizens on Duratus, Luna, Mars, and elsewhere would continue to be met without too much struggle, indeed by the standards of many past civilizations the Legion remained unimaginably prosperous, the Trans-Newtonian components of the Legion economy would surely collapse without TNEs to fuel them, and given the coupling between lack of resources and passage of time, eventually even the basic infrastructure which met the needs of the populace would succumb to disrepair.
Legion Demographics in Y4100:
Capital:Duratus: 1.79b population, ~3/4 of Solar industry, scientific and naval center of the Legion
Major Colonies:Luna: 185m population, 1,000 financial centers
Mars: 450m population, 500 fuel refineries, 10 ground force construction complexes, Martian Naval Academy
Mercury: 75m population, 30,000 infrastructure units; all former industry has been relocated off-world
Venus: unpopulated except for military garrison, 400 automated mines
Offworld Mining:Ironforge Mining Site (1995 TL8): 9m population, 30 mining complexes
Firegate Mining Site (1997 CU29): 3.3m population, 16 mining complexes

The Duranium Legion Navy in the Year 4100In general, both the military and auxiliary components of the Legion Navy at this time could be divided into two categories. The first of these categories contains the comparatively advanced “Lost Technology” vessels which had survived the Civil War and the following years of decay and remained in Legion Naval service. Many of these had been constructed prior to or during the first decade of the XLI century and the reader of the first volume in this series will be intimately familiar with them, although any reader may refer to the attached
Compendium to review these specifications at their own leisure. A few ship classes, however, require a closer presentation:
The
Leviathan-class heavy cruisers began construction in 4010 following the Naval Conference of 4009, and were intended to form the backbone of the revamped Legion Navy along with the
Manticore-class command cruisers. Following the established doctrine of the time, these were all-railgun cruisers with a broadside of heavy 203 mm weapon batteries backed up by a dozen 102 mm point-defense batteries, encased within a full meter of composite armor plating. At least a dozen of these vessels, along with three of the command cruisers, were constructed from 4010 until about 4027 when the resource crisis forced a moratorium on capital ship construction. Most of the
Leviathans along with all three
Manticores were destroyed in the Civil War, and only two examples survived until 4100.

This moratorium ended with the onset of the Civil War, with the resource-limited run of three
Poseidon-class 35,000-ton dreadnoughts, all of which were armed with the monstrous Arcadia 279 mm Capital Batteries and all of which were destroyed in battle after impressively short service lives. Legion Naval analysts soon concluded that as powerful as the 279 mm batteries were in terms of raw firepower, they were simply not effective at long enough ranges to prevent the massive capital ships from being swarmed and picked apart by the smaller, more numerous
Invincible and
Leviathan-class cruisers they opposed in battle. To rectify this, the Lords Admiralty approved the construction of two 37,500-ton
Retribution-class dreadnoughts, with railgun armaments barely better than that of a
Leviathan. This was more than made up for by the presence of four massive PEL-12 neutron lances capable of skewering any smaller vessel without a second thought. Construction began in 4047, but the building process was plagued by continual resource and financial shortages, and the two dreadnoughts were only completed after the War, largely as a means to intimidate the surviving Lords of the Legion to keep in line, and as such the
Retribution class never saw combat during the XLI century.

Astute readers of the first volume in this series will note the absence of the
Bellerophon class or its successors from the above roster. All evidence indicates that every example of this class was destroyed during the Civil War, in large part due to continued doctrinal misuse of the class which was admittedly ill-suited for the chaotic battlefield of such a nebulous internal conflict.
Post-War Legion Navy Vessels:
The
Seraphim-class frigates were, strictly speaking, not a “post-War” class as they were designed towards the end of the war as the Lords Admiralty recognized the need for an affordable ship class to fill secondary roles using technology which could be rapidly built and easily maintained. This need was met by the use of cheaper, low-performance gas-core engines rather than the powerful ion drives typically preferred by the Legion Navy, a change which also necessitated a triple-engine configuration rather than the historically favored twin ion drive setup. Following the destruction of the Arcadia family of Lords and their associated weapons manufacturing assets, Lord Thomas Acheron attempted to meet the needs of the Legion Navy by replicating the Arcadia railgun designs as best as possible, but ultimately was only able to present the Lords Admiral with an inferior 122 mm weapon. This proved barely sufficient for secondary combat duties, but would later give excellent service against the rather poorly armored raiding ships which commonly harassed Legion shipping in the post-War era. In 4100, sixteen examples of the class were in service in four patrol flotillas, although due to the economic crisis and a general lack of pirate activity these rarely went out on actual patrols.

The
Victorious-class scout cruiser was authorized for a limited three-ship production run at the height of Solar system bandit activity in the 4080s. The patrol-class sensor suites of the
Seraphim-class frigates, while having greater range than anything else the Legion Navy was capable of building at the time and indeed better than anything aboard the surviving “Lost Tech” ships, had proven insufficient to reliably detect and intercept wily pirate flotillas. The
Victorious class was introduced solely as a transport platform for the fast SC-64 Raven scouts, which could not only outrun any pirate vessel but could also range ahead of a patrol or escort group as advance scouts. Ultimately, however, the
Victorious class provided no real upgrade in terms of firepower, and bandit groups rapidly adapted to the new class by deploying heavier armaments, largely by equipping plundered 152 mm batteries which badly outmatched the 122 mm batteries of the frigates.

The
Warspite class was a fairly successful attempt by the Legion Navy to strike a decisive, final blow against the bandit plague in the Solar system. The heavy armor and long-range beam cannon armament proved too much for all but the wealthiest and best-equipped pirate fleets to stand up against. While the PEG-3/C was a clear downgrade from the older PEL-4 mounted by the infamous
Hellfire class frigates, it was sufficient to outrange the 152 mm batteries mounted by the most dangerous raiding vessels, and neither PEL-4s nor PEG-3/Cs were readily available to any pirate faction (although at least one pirate lord tried and failed to abscond with a
Hellfire-class frigate to overcome this imbalance). Despite the more-than-superficial similarities to the venerable
Invincible-class light cruisers, the Legion Navy chose to designate the
Warspite class as a full cruiser, likely for the sake of projecting a more impressive public and political image.

The one area of “Lost Tech” ships which the Lords Admiral found no need to augment was jump drive capability, for rather obvious reasons. As such, no new fleet tender, stabilization, or survey capabilities were introduced in the post-War era.

The Duranium Legion Ground Forces in the Year 4100Following the Commandant-Major Crisis of 4009-4010, the Legion Ground Forces had been forced to reorganize into primary-arms brigades rather than the artillery-integrated brigade system in use prior to the Year 4000. As this left individual brigades somewhat understrength, requiring ~15,000 tons of transport capacity compared to the previous ~20,000 tons, new means were sought to restore the original combat strength of the brigades prior to the planned invasion of the Belaire home world. While these plans were unfortunately cut short by the Collapse, research and development efforts were already underway, and throughout the 4010s and early 4020s the Ground Forces were blessed by an overflow of power-armor troopers, heavy tanks, and heavy self-propelled artillery vehicles with which to augment their formations.
The Legion ground forces came out of the Civil War with remarkably little wear and tear, a consequence of the relative lack of ground combat operations carried out during the War, this in turn being a direct consequence of a relative lack of transport capacity, which had hardly recovered from nearly total losses to the Belaire front after the Collapse. As such, most of the advanced force units of the 4020s had not only survived but in many cases more had been built during the War in anticipation of significantly heavier combat than had in fact been seen. What did hit the ground forces hard was the following economic and technological collapse in the early post-War period, during which the capability to develop and manufacture advanced weapons and equipment were largely lost, or in some cases cannibalized by the Navy, which, while desperate, nevertheless held the key advantage of having numerous very large railguns parked in orbit above the ground force bases. This latter factor later motivated the relocation of the ground force construction and training facilities to the Martian colony, where they would at least not be conveniently adjacent to the primary Legion Navy fleet base at Duratus.
From the mid-4070s onward, newer weapons and equipment were developed to replace most of the older types due to chronic lack of manufacturing or maintenance capabilities for older munitions. However, by the end of the XLI century the ground forces still had not recovered the capability to produce power armor, heavy tanks, and other similarly advanced weapons, and if any of these were to be somehow lost in combat, replacements would be years, if not decades, away.
Duranium Legion Ground Forces Formations in Y4100:
The Commandant-Major Crisis of 4009-4010 ultimately forced the Lords General to reorganize the ground forces at a high level to satisfy the complaints of disgruntled non-Lords senior officers, reserving command of the battalion-level formations for the Commandants Major. Initially, this led to the creation of a somewhat superfluous “regimental” command level so as to find employment for the large number of Subcommandants who would otherwise find themselves out of a job but could not simply be promoted to brigade-level commands. Over time, however, the regimental commands were phased out as Subcommandants were promoted at a high rate, assuredly for unrelated reasons, and whatever limited attrition was suffered by the ground forces during the Civil War served as a convenient excuse to can the concept once and for all. In the post-War era, then, the basic Legion ground forces formations consisted of three primary-element battalions augmented with a battalion of advanced-tech units to provide heavy firepower support.
The Mechanized Infantry Brigades remained the most numerous formations in the Legion ground forces as well as the multi-role workhorse units in daily practice. While consisting largely of leg infantry and therefore reasonably suitable for defensive missions, Duranium Legion doctrine and culture demanded that the infantry mission be first and foremost offensive in character, and thus full mechanization of the infantry arm remained mandatory even throughout the economically challenging post-War period. The general vulnerability of the infantry to concentrated anti-personnel and high-explosive firepower was largely mitigated by the inclusion of a heavy power trooper battalion, which served in a shock assault role and could lead the charge against a heavily-defended enemy position while suffering substantially fewer losses. Of course, despite the typical eagerness of a Legion Commandant, this purported capability had rarely been tested, indeed some would argue that it had never been
properly tested, prior to the XLII century.

The Tank Brigades, as they had since time immemorial, remained the most prestigious arm of the Legion ground forces, a status no doubt nontrivially attributable to the superior offensive capability of heavily armored vehicles in the face of a hardened opponent. What had changed since time immemorial was the addition of a full battalion of fearsome Colossus heavy tanks, which benefited not only from being the heaviest front-line weapons on any battlefield but also from having been designed and built using advanced ceramic composite armor technology at the height of Legion scientific advancement. As the spearpoint of any armored assault, the Colossus heavy tanks had received precious little battlefield testing, but unlike their power-armored infantry counterparts the results had left little room for detractors to register any substantive complaints.

The third arm of the Legion ground forces were of course the Mechanized Artillery Brigades, which provided crucial supporting fire for the advances of the Legion’s brave infantry squads and tank crews. The self-propelled artillery forces had been historically split between light and medium battery calibers, and as this had been a very successful arrangement the Lords General had seen no need to make any change here even up to the year 4100. Where greater firepower was required to defeat the most hardened enemy positions, a battalion of two dozen Vesuvius heavy SPGs in four batteries was attached to every artillery brigade. Unlike their frontline equivalents, the advanced-tech Vesuvius SPGs had never been tested in battle prior to 4100, and many among the ground forces artillery arm whispered in private that this was perhaps for the best, as while the Vesuvius was sure to deliver devastating firepower, many doubted that it could be worth the rather prohibitive cost of ammunition in those economically trying times.

Higher command and control was provided by Corps and then Legion headquarters formations. These had perhaps undergone the most change compared to the pre-Year 4000 orders of battle, having found room for a platoon of organic combat engineering vehicles as well as an additional battalion of Vesuvius heavy SPGs. While this did imply a reduction of organic logistics assets with which to support and resupply the front-line formations, in practice this was offset by redistribution of some logistics assets to the brigade commanders, as well as the holding of additional supplies in the rear areas, organized into Logistics Brigades under the Legion command level, which could be used as reinforcements when necessary.

The Logistics Brigades themselves were simply organized, consisting of three primary logistics battalions which would handle resupply and maintenance of front-line formations, along with a full battalion of combat engineering vehicles to accelerate the construction of front-line fortifications, whether for garrison duties or in the event of an extended planetary conflict.

Finally, the Legion ground forces did control several auxiliary formations. The original Ground Survey and Xenoarcheology Brigades of the pre-Collapse era had been preserved throughout the years, in both lineage and in equipment as the heavy Gorilla and Styx vehicles of each formation, respectively, were each nearly one hundred years old. More recently, in the last decade of the XLI century the Lords General had authorized the construction of several Surface Defense Battalions, each consisting of six AK-155 Medium Surface Batteries and six PEG-3/C Surface Beam Cannons, weapons purchased from the Navy after much haggling when it turned out that the Navy could not afford to construct sufficient hulls to actually deploy these weapons. These battalions were deployed on Duratus and the major colonies in the Solar system, ostensibly for defense against bandit raids and any other threats which might arise, but conveniently placed so as to threaten the Legion Navy should the Lords Admiral happen to get any interesting ideas about the balance of power in the Sol system.

Legion Ground Forces Order of Battle in the year 4100:
The Legion ground forces at this time consisted of 232,000 combat personnel operating 2,260,000 transport tons of weapons and equipment, in addition to roughly ten million support and auxiliary personnel based chiefly at the colony on Mars. This would be considered more than adequate for system and colony defense, but should the Legion ever find its way back to the stars a significant expansion of capabilities would once again be necessary. At this time, the offensive mission for the various Legions (notably the Assault Legions) was geared primarily towards the suppression of any rebellious movement which could herald a return to Civil War-era tensions and violence.
