Aegiran Army

The Aegiran Army is the republic's land force, organized for garrison and coastal defense of the four federal islands and for limited coalition expeditionary deployment. Approximately 24,000 active personnel with 22,000 active reserves — the smallest of the three combat services, reflecting Aegira's primarily-naval strategic posture and the Marine Corps' assumption of the principal land-combat role.

The Army's missions are garrison, coastal defense, and limited coalition expeditionary deployment. Sustained continental land operations are not part of the Aegiran Army's doctrinal repertoire; the republic's strategic posture does not require them. The Army is small enough that it is organized at the brigade-and-battalion level — there are no Aegiran Army divisions.

Doctrine

The Army is doctrinally organized around three roles:

  1. Garrison and territorial defense of the four federal islands, providing infantry, artillery, and armored support to fixed defensive positions and rapid-response operations
  2. Coastal defense in cooperation with the Stolos's Coastal Defense Command — Army formations provide the ground-side infantry and armor that complement naval coastal artillery and harbor defense
  3. Limited coalition expeditionary deployment through the single Federal Expeditionary Brigade, available for WDP coalition operations elsewhere in Sierra when the republic's domestic security situation allows

The Army is infantry-heavy with substantial supporting arms but limited armored mass. Aegiran terrain — small islands with limited interior, no large continental maneuver spaces — does not reward the development of large armored formations.

Principal formations

The Federal Expeditionary Brigade

A combined-arms brigade with two mechanized infantry battalions (Marder IFV), one armored squadron (Challenger MBT — priority recipient of the modernization tranche), an artillery battalion (PzH 2000), and engineer and logistics battalions. Coalition-deployable; trained for operations alongside WDP partner formations.

The Expeditionary Brigade has historically been the Army's most-tested formation, deployed to several peacekeeping and coalition operations across the post-Chartania era. As of late 2026 it is not committed to the eastern islands recapture campaign (that is a Marine operation) but is available for deployment to the broader Continuation War coalition fronts.

Federal Island Garrison Command

A single command structure covering all four federal islands. The Krygos Garrison Brigade is the largest formation (a full mechanized brigade); the Pharos and Heliopolis Garrison Battalion Groups are battalion-group-strength formations with mechanized infantry, coastal defense, and engineering elements; the Northern Fringe Battalion Group is a light infantry formation for the smaller northern islands.

Each garrison formation includes a Coastal Defense Battalion integrated with the Stolos's Coastal Defense Command — these battalions operate the truck-mounted coastal anti-ship missile batteries (RBS-15 KA equivalent), coastal artillery, and harbor-defense infantry that complement naval surveillance and minelaying.

Federal Reserve Brigade

The Army's 22,000 reservists are organized as four mobilization battalions per federal island, totalling sixteen reserve battalions. Full activation timeline is 30 days; on activation the reserve battalions reinforce the garrison formations.

Federal Coastal Artillery Command (joint with Stolos CDC)

A combined Army-Navy command structure providing the ground-side complement to the Stolos's Coastal Defense Command. Heavy artillery, the substantial ground-based portion of the republic's anti-ship missile capability, and the supporting infrastructure (depots, fire-control centers, surveillance) are part of this joint command.

The FCAC is one of the more capable in central Sierra, reflecting the republic's need to defend a dispersed island archipelago against amphibious threat. The 2026 fall of the eastern islands has triggered substantial FCAC investment for the remaining federal islands.

Equipment

Aegiran Army equipment is broadly conventional WDP-pattern peer-tier, in the active modernization tranche described in armed-forces.md:

  • Service rifle: FN F2000 (5.56×45mm bullpup) — AFDF service rifle
  • Main battle tank: Leopard 1A1 (Leipzisch legacy, ~80 hulls, phasing out) and Challenger 2/3 (Eurekan modern, ~40 delivered, target ~80 by 2030). Garrison and reserve formations retain Leopard 1A1; the Expeditionary Armored Squadron is the priority Challenger recipient after the Marine Armored Battalion
  • Infantry fighting vehicle: Marder 1A3 (Leipzisch export, ~150 hulls) — principal AFDF IFV
  • Wheeled IFV / APC: Boxer (wheeled IFV); Fuchs (wheeled APC and recon, transitioning to Piranha-class)
  • Tracked APC: M113 (Arcadian export)
  • Light tactical vehicle: G-Wagen (Leipzisch export)
  • Self-propelled artillery: PzH 2000 (Leipzisch export, 155mm)
  • Towed artillery: M777 (155mm, Arcadian export); M101A1 (105mm, retained in reserve)
  • MLRS / tactical missile: M270 with ATACMS (Arcadian export)
  • Coastal artillery: truck-mounted coastal anti-ship missile batteries (selection TBD; likely RBS-15 KA Bofors-Gorlish or NSM equivalent)
  • Air defense: Patriot (long-range); TOR M-1 (medium-range, Volnian export); ASRAD HELLAS (SHORAD); RBS-70 NG MANPADS distributed

Special operations

The Army Long-Range Reconnaissance Company is the Army's SOF element — a small army recon-SOF asset for island defense, reporting to the AFDF Special Forces Command. AFDF SOF is concentrated in the Navy (Frogman Detachment) and Marines (Reconnaissance Battalion); the Army contribution is correspondingly small.

The July 2026 eastern islands action

The Aegiran Army on the eastern islands at the outbreak of the war consisted of two reinforced infantry battalions and a coastal artillery group. These formations supported the Marines in the delaying action and took proportional casualties; the formal losses (approximately 800 killed, 1,600 wounded, 400 missing or captured) were proportionally similar to Marine losses but absolute losses were smaller given the smaller forward-deployed strength.

The Army was broadly successful in its eastern islands role — coastal artillery inflicted disproportionate casualties on CSAT amphibious shipping; infantry battalions provided organized resistance allowing Marine and civilian evacuation. The institutional verdict on the Army's eastern islands action is favorable.

Current operations (Continuation War)

The Army is in wartime posture:

  • Federal Island Garrison Command: full garrison strength on the four federal islands; rapid-response postures; civilian-defense cooperation
  • Federal Expeditionary Brigade: ready for WDP coalition deployment; not currently deployed
  • Federal Coastal Artillery Command: full readiness; expanded mining and fixed-defense activity around the federal islands' approaches; Coastal Defense Battalions reinforced
  • Reserve mobilization: territorial reserve brigades partially activated; manning approximately 80% of authorized strength
  • Challenger transition: Expeditionary Armored Squadron receiving its first Challenger tranche after the Marine Armored Battalion

The Army has not activated full conscription and operations remain within the volunteer-and-reserve mobilization framework.
