Frisian Swierslachienheid (SSI; yng. 'Heavy Battle Unit')
SSI graphical table of organization, A.D. 2049.
Established as part of a raft of military reforms ushering in the restored monarchy in the late 2020's, the Heavy Battle Unit is the basic formation of the Frisian Legion's Lânmacht for the XXI century, based on observations of Oumeian and Haudenausoneese military developments, with the unique characteristics of the Frisian Empire in mind. The intention behind the SSI was a "clean break" from 15th century adaptations of ground forces, itself endemic the world over, and ultimately originating from the Gallic king Sigismund II Karolus and his successful Great Northern Wars against the Hsingnu Khagans, to a new formation designed purely for 21st century requirements leveraging the last great revolution in military affairs, the internal combustion engine, to its fullest extent. High mobility, shock action, dispersion, independent operation, and adaptation to the latest 3-meter broad gauge railroads of the Frisian Empire's land connections.
The Heavy Battle Unit was complemented by the correspondingly named Light Battle Unit (
Ljochtslachienheid; LSI), a battalion-sized force of motorized infantrymen and robotic combat systems primarily moved by road marches or cargo helicopters; and the Medium Battle Unit (
Middelgewichtslachienheid; MSI), a formation primarily moved by Boxer WAFVs, thus able to be road marched, but possessing greater firepower and protection than the LSI; and the Cruiserweight Battle Unit (
Krusergewichtslachienheid; KSI), a less radical and more austere version of the Heavy Battle Unit, using Finn main battle tanks, Gerhard tank support vehicles, Pugilist IFVs, Fencer armored load carriers, and relatively ordinarily equipped mechanized infantrymen.
These "units", of any stripe, would replace the old fashioned "battalion" of the Late Medieval/Gallic paradigm, containing sufficient firepower and equipment to fight and engage along the lines of a late 20th century division. There was particularly high amount of promise held for the Heavy Battle Units, which were considered to be a suitably capable response, given Frisia's tremendous demographic disadvantage, to the traditional Gallic penchant for massive nuclear firepower concentrated in large, cumbersome field formations. The program was intended to produce three LSIs, a dozen MSIs, nine KSIs, and six SSIs at the end of the 2040's. Each Operational Action Unit, comprising three Battle Units (ground forces), a Support Unit (logistics), an Aviation Unit (fighters and UARs), and in non-SSI Action Units, a Fire Unit (artillery), would replace the Legion's corps and their archaic organizations. Support troops, in the form of combat engineers and railroad troops, would act in concert with the OAU, providing mobility over obstacles and end-point connections between the Guild War economy and the field forces. Each SSI would be supported by 36 Barrage fighters, a next-generation combat aircraft, intended to replace the ~950 Hurricane fighters in service with the Loftmacht then in 2028, generating a requirement of 360 combat aircraft, 120 training aircraft, and 54 spare/backup airframes for supporting the ground troops. The requirements for the Frisian Navy, 240 combat aircraft, 158 training aircraft, and 48 backup aircraft, made a total requirement of 980 airframes of both varieties. Ground support and "colonial tasks" would be carried out by the Fokke Fusillade light strike jet/advanced trainer, of which nearly 650 of a requisite 1,280 had been procured by 2049.
This ambitious military modernization, like all others of its kind, mostly failed to materialize. Although the Frisian military-defense industry was relatively advanced its industrial output lagged behind its neighbors in the UZR and Galla, with the bulk of equipment being essentially fitted out by hand in limited throughput ateliers. By 2048, approximately 128 Autonomous Armored Units, the centerpiece of the SSI, had been produced, giving sufficient equipment for three SSIs and the entire metropolitan Milysje. Equipment of one LSI, three MSIs, and two KSIs was also procured. The remainder of the Frisian Lânmacht, approximately 400,000 personnel, were organized into divisions, brigades, and battalions of relatively conventionally organized, albeit decently equipped, and never fully transitioned. The requisite air forces, nearly a thousand 9th generation Barrage fighters, barely amounted to a quarter of this number in practice, and only after squeezing every last airframe to frontline forces. Although adequate for emergency combat use, the aviation elements of most Battle Units were more often 7th generation Hurricanes instead, or the Fokke light attack trainers.
Putting the modernization into context, by 2028 the median age of Frisia had risen to 48, and by 2050 it would top 54 years, joining the ranks of other greying nations. The populations of the two countries in 2020 was also substantially different, with Frisia's metropole topping 60 million and its colonies adding another 35 million of militarily viable population, for a total of approximately 95 million citizens to draw on. Serfs and levies (non-voting populations with few civic responsibilities) were not counted in this number. Against this, the population of Galla, subject to conscription in its entirety, broached 155 million in 2020, and expected to brush between 180 and 190 million by 2050; with a median age of 30 in 2022 and this was expected to climb to 35 by 2050. Mobilization estimates by the Frisian General Staff had placed the total manpower of the active Gallan Army as a hair over 1 million men, with approximately 20 field divisions and a dozen independent regiments and brigades, and this was unlikely to change over the coming decades. The Frisian Lânmacht, in 2025, possessed a mere 8 field divisions, with three organized along the lines of deployable brigades, intended to be rapidly moved around its imperial periphary. A pair of corps of five field divisions, organized as heavy armor formations, were earmarked for defense of the metropole, including Southern Frisia. A handful of separate brigades, typically special purpose, rounded out the deployable formations. A total number of 450,000 ground troops, with another ~150,000 in reserve troops, opposed nearly a million ground troops. More concerningly, however, was the reserve formations of the Gallan Army which were organized into three major rungs, based on age of equipment and age of personnel, with the most conservative estimates placing a lower bound of 90 deployable field divisions and approximately 4-5 million ground troops in the Gallan Army, and the most alarming ones suggesting as many as double this, with temporal expectations varying between first divisions reaching formation within three months and rounding out by nine months, to twelve months and twenty four months respectively. Similar disparities, although not as extreme, were witnessed in air power and naval power. Thus, a way to mitigate the threat posed by the Gallan Army would be formations which could inflict loss:exchange ratios of between ten to twenty, with an idealized number of approximately 15 in open terrain, against the initial formations of 20 divisions. General Staff estimates expected that as time went on, the capabilities of the Gallan Army would be degraded faster than Frisian units, allowing them to attain even higher LERs against less capable formations of the reserve ("ersaettning") formations, and eventually grind the Gallan Army to nothing, even in the event of a strategic nuclear attack.
All the SIs, with the exception of the SSI, used existing equipment such as armored vehicle hulls or utility trucks. These existing units were provided with improved communications gear and occasional addition of long-range weapons at lower levels (battalions receiving a battery of field guns, platoons having multi-kilometer range missiles, etc.), intended to give the SI the ability to operate at frontages of 60-90 kilometers vice the 20-30 kilometers of latter half XX century formations. This would give the SI a similar "envelope" as a "brigade", and the OAU "brigade equivalent" a comparable footprint to a field division. The intent being to drop the requirement of personnel by an order of magnitude, while maintaining their existing killng power and reducing their vulnerability to nuclear attack. Although the SSI was always going to be the "end-state" of the modernization, this was unlikely to be achieved before 2070 at minimum.
The performance of the SSI shouldn't be underestimated, as even in its less-than-ideal state a triplet of SSIs supporting 9.OAU of the Frisian Sajaric, supported by a tactical fighter wing (48 airframes) of Army land-based Barrages and 80 Navy Barrages, a force barely numbering over 8,000 troops, managed to bring a mobile, modern field army of ten times its own size into combat, avoided a decisive engagement even in the face of tactical nuclear weapons, and eventually forced the field army into retreat, despite limited support in theater from the industrial base, with relatively few losses, collectively amounting to a single SSI, and the near total destruction of the field army's materiel. The embarrassing rout of the Gallan 1st Field Army, replete with stolen sedans, pickup trucks, and buses carrying scores of injured and wounded armored vehicle and aviation crewmen, now unhorsed, was saved from becoming a Frisian propaganda coup due to the state of telecommunications across Alaria and North Sajarica.
Organizationally, the SSI is extremely lean, with the bulk of support elements in the OAU. As it is intended to operate at extreme frontages, with 500 meters or more between the individual frontline soldiers (in practice, closer, as troops operated in pairs for safety, with robotic recce systems filling in the gaps), the firepower of each individual system is extensive. Further, so is the mobility of both troops and ground vehicles. Within the Sajaric Plains, the frontages of the 9.OAU often approached 300 kilometers in the attack, and 600 kilometers in depth. SSIs A, B, and C of the 9.OAU were involved in Operation
Boefbatsjend, opposing the crack 1st Field Army's three divisions, the Royal Marines' 40th Commando Division, 1st "Karolus Magnus" and 7th "Roland" armored divisions, approximately 90 tactical fighters (JAS.15EX Ornen fighter-bombers; Eagle), and the 173rd Paraglider Brigade, approximating its opponent. SSI-A and -C successfully managed to avoid getting pinned down as the 1st Army attempted to chase them across the desert for nearly three months. Supported by their Atenist allies, soldiers of the 1st Mechanized Division overran a staging area of the Tactical Subunit of SSI-B, somehow capturing a Z.Hw.Sp.13504/220 Autonomous Armor Unit and destroying a second vehicle, with these units and their two-dozen battlesuit riders the only major Frisian Lânmacht casualties of the 9.OAU.
