Arcer Army

The Army of Arcerion is the largest branch in terms of personnel and mission set, however it is not the oldest branch of the Armed Services, with the senior branch being the Arcer Navy, which itself draws its lineage from the Arcer Maritime Patrol Service during the days where Arcerion was a Carnish colony. The Army itself is broken down into Active and Reserve components, with roughly 25-40% of troops belonging to Active, full-time Regiments, and the remaining being Reservists serving part-time.

Formation
The Arceiron Army was initially formed as local militia and garrison units to support regular Carna soldiers stationed in the colony during Royal rule. However, as Carna itself evolved, and Arcerion gained more independence, these soldiering formations took on more and more of the governance, security, and border patrolling duties from their colonial masters, who instead withdrew to the cities, leaving the wild plains of Arcerion to be patrolled by soldiers born and raised there. The first regiment, the Arcerion Loyal Militia, was formed in 1793, and it is from this unit that the Army draws its lineage. Many of its Regiments have named their individual rifle companies after the Militia's own, for example in the 1st Battalion, Kurst Foot Grenadiers, the 'A' Company, or first of the battalion, is known as "Loyal," Company, an homage to the Militia.

the Militia would serve with distinction throughout the many border skirmishes and internal conflicts in Arcerion during the formative years, resulting in lessened Carnish presence in Arcerion, and by the 1850s, only a few token companies of Carnish soldiers remained in the capital to maintain a foothold, whilst Arcerion was able to police and secure its own borders successfully up to this point.

Organization and Doctrine
The Arcer Army is centered around its brigade groups, which as per the 2022 Confederate Memo on Defence, are focused around infantry battalions with supporting ISR and fires assets, while maintaining their integral engineer and light armour support. Where the Army lacks is in heavy, direct-fire support. being a legacy colonial military, the emphasis on excellent light infantry and skirmishers, complemented by its garrison artillery and mobile cavalry reinforcements. The transition to today has seen this result in superb light infantry battalions, with an emphasis on motorization and the ability to cover open country, such as the Governate of Northlea, quickly. The garrison and coastal artillery units have meant that the modern Regiment of Arcer Horse Artillery (RAHA) has an exceptional understanding of modern fires planning, as well as the usage of ISR for targeting. The cavalry gradually evolved into two branches within the Arcerion Armoured Corps, the Cavalry branch and the Armoured Reconnaisance Branch; the former being tanks and direct-fire support vehicles, and the latter focused on ISTAR.

The Army has several types of Brigades, all centered around an infantry Regiment, Below are some of the active Regular Army infantry and engineer regiments of Arcerion, and their garrison locations.

The Arcer Army order of battle centers around the creation of combat teams, which themselves are a combined-arms effort of multiple Corps and Branches within the Army. The Combat Team is the main operational arm of the Arcer Army, and while not the lowest operationally-tasked unit (that being the company), it operates as a self-contained unit able to conduct offensive, defensive, and stability operations. The Combat Team is comprised of (1) infantry company with (1) platoon-sized element of supporting combat engineers, (1) forward observer vehicle from the Regiment of Arcer Horse Artillery, (1) squadron-equivalent formation of supporting armour or direct fire (ie. armoured reconnaissance or main battle tanks), as well as a rear echelon including medical staff, signalers, vehicle and maitenance technicians, and other enables as required. The convention for the Combat Team is that it is organized and commanded by a Major (OF-3), or a senior Captain (OF-2) in extremis with either operational experience or with the necessary qualifications. The 2IC, or 2nd in Command is a Captain. Individual formations and sub-units within a Combat Team are usually Lieutenants (OF-1). NCOs are present without, with several Warrant Officers (OR-8) and Colour/Staff Sergeants (OR-7), present to provide subject matter expert advice as well as guidance.

The Army above the combat team is organized into Battalions or Regiments, each commanded by a Light Colonel (OF-4). These Regiments and battalions are centered on a combat arms unit, and formed into the Arcer Army's fighting brigades, the most common being infantry. Brigades are each commanded by a Colonel or Brigadier (OF-5). These brigades are grouped into their own Divisions, of which Arcerion has 5, 3 full-time divisions dedicated to rotating through a high-readiness cycle, and the other two being Reserve formations responsible for the administering of professional development courses, battle schools, centers of excellence, and fulfilling staff functions.

The Divisions, 1st-3rd, 5th, 7th, all have storied lineages dating back to the Great War, and all of which carry battle honours won fighting side by side with Urcea and Carna. The divisions are each usually commanded by a Brigadier or Major-General. Divisions are subordinate to Army headquarters, and are parallel in organizational size to Army Special Operations Command, which is itself commanded by a Major-General and reports to the Commander, Army General Staff.
