Aegiran Army¶

The Aegiran Army is the republic's land force. 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 Marines' assumption of the principal amphibious infantry 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.

Doctrine¶

The Army is doctrinally organized around three roles:

Garrison and territorial defense of the four federal islands, providing infantry, artillery, and armored support to fixed defensive positions and rapid-response operations
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
Limited coalition expeditionary deployment through the single 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.

Force structure¶

The Army is organized into:

One Expeditionary Brigade — the Army's coalition-deployable formation; combined-arms, ~5,000 personnel
Four Territorial Brigades — one per federal island (Krygos, Pharos, Heliopolis, Karthago); garrison, coastal defense, and rapid-response
One Armored Battalion — small armored formation, principally for the Expeditionary Brigade
Federal Coastal Artillery Command — integrated with Stolos Coastal Defense Command; provides ground-mounted heavy artillery supporting the harbor approaches
Army Reserve Brigades — territorial defense reserves on each federal island; mobilization-dependent
Federal Air Defense Command — ground-based integrated air defense (overlapping with Air Wing responsibilities)

Principal formations¶

The Expeditionary Brigade¶

A combined-arms brigade with three infantry battalions, an organic armored battalion, an artillery regiment, and combat support and combat service support elements. 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.

Territorial Brigades¶

Each of the four federal islands has a Territorial Brigade providing:

Infantry battalions for island defense and rapid-response operations
Limited armored support
Light artillery and mortar capability
Engineer, signals, logistics, and medical support

The Territorial Brigades are competent rather than elite. Their personnel are predominantly career professionals supplemented by reserve activations.

Federal Coastal Artillery Command¶

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 FCAC.

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.

Federal Air Defense Command¶

Ground-based integrated air defense providing:

Long-range surface-to-air missile (SAM) batteries protecting the major federal islands' airspace
Medium-range SAM batteries protecting key infrastructure
Short-range air defense (SHORAD) attached to Army formations
Air-defense radar and surveillance network integration

FADC is administratively under the Army but operationally coordinates with the Air Wing for fixed-wing air defense and with the Stolos's coastal surveillance for maritime air-defense overlap.

Equipment¶

Aegiran Army equipment is broadly conventional WDP-pattern peer-tier:

Service rifle: TBD (Aegiran Federal Service Rifle — IL-style modular, 5.56mm)
Main battle tank: TBD (limited number; principally for the Expeditionary Brigade and selected Territorial Brigade support)
Infantry fighting vehicle: TBD (peer-tier IFV; standard mechanized infantry mount)
Wheeled armored vehicles: TBD (substantial inventory for territorial defense)
Self-propelled artillery: TBD (155mm howitzer family)
Coastal artillery: heavy fixed and mobile; including the substantial anti-ship missile capability
Air defense: TBD (layered SAM and SHORAD)
Anti-tank weapons: ATGM-heavy

Bases¶

Base	Island	Role
Camp Themistocles	Krygos	Army headquarters; Expeditionary Brigade base
Fort Aegis	Pharos	Pharosian Territorial Brigade; coastal defense
Camp Korinthos	Heliopolis	Heliopolitan Territorial Brigade; FADC headquarters
Camp Brasidas	Karthago	Karthagian Territorial Brigade
Federal Army Academy	Krygos	Officer training

The 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:

Territorial Brigades: full garrison strength on the four federal islands; rapid-response postures; civilian-defense cooperation
Expeditionary Brigade: ready for WDP coalition deployment; not currently deployed
FCAC: full readiness; expanded mining and fixed-defense activity around the federal islands' approaches
FADC: full readiness; expanded air-defense coverage; integration with WDP coalition air-defense networks
Reserve mobilization: territorial reserve brigades partially activated; manning approximately 80% of authorized strength

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