The Royal Arcerion Regiment is the senior line infantry regiment of the Arcer Army's Royal Arcerion Infantry Corps. It consists of seven battalions, of which two are reserve, each of which forms its own individual regiment. Both Reserve Battalions have their own distinct regimental colours and honours, as they carry the lineage of two deactivated/antecedent regiments. The modern Regiment has undergone several changes and amalgamations, but has existed in its current structure since the late 1990s. It shares the joint honour of the oldest Regiment in the Arcer Army with the Royal Moorden Regiment, from their shared lineage to the Arcerion Loyal Militia, however the Royal Arcerion Regiment received its Regimental colours and status from the Ardmori Crown first.

The Regiment's battalions form the central elements of 1 Rifle Brigade and part of 4 Mechanized Brigade.

Regimental Museum

The Royal Arcerion Regiment Museum is located in Dalfearn, and is a tourist attraction that annually draws 250,000 visitors. It has trophies, photos, videos, and donated artifacts from the Regiments 200+ year history and is managed by the RAR Association. It has exhibits for children and adults, as well as a walk of remembrance up to the "Rifleman's Monument," which is dedicated to all the fallen members of the Regiment from founding until the modern era.

The Regimental Colours are housed in the museum, and removed and used by the Regimental Headquarters for ceremonial events. The museum has a planned expansion estimated to cost £2.4 million Arcer Pounds, and is scheduled to be completed in 2030. This will include the creation of a museum rugby pitch, as well as the construction of a vehicle hall for the light and armoured vehicles as well as heavy weapons, used throughout the Regiment's history.

Structure

Garrison locations of the Royal Arcerion Regiment's Battalions and Regimental Headquarters.

With the resturcuring of the Regiment in the 1990s to accomodate the inclusion of new Regiments, the Battalions and Companies were renamed to reflect the honours and heritage associated with their new units. The current structure as of 2026 is as follows:

1st-7th Battalions, Royal Arcerion Regiment

• A Company
• B Company
• C Company
• D Company
• Weapons Company

The 1st, 2nd, and 3rd Battalions operate in the mechanised role as part of their respective Brigade groups. Following the 2022 Confederate Memo on Defence, the 1st-3rd Battalions will remain in this role but receive additional vehicles and equipment to create more versatile battlegroups. 1st, 2nd, and 3rd Battalions are headquartered at the McCaffery Barracks in Dalfearn, with the Regimental Headquarters.

The 4th Battalion also operates in the mechanised configuration, however it is displaced and garrisoned in Presdale at Essex Lines, Arcerion Maneuver Training Centre.

The 5th, 6th, and 7th Battalions operate in the Light Mechanised role, and are based along the southern Arcer coast in Moorden Governorate. As part of the 2022 Confederate Memo on Defence these battalions will receive an additional company of troops to be augmented from the Army Reserve. 7th Battalion also maintains a ceremonial contingent to assist the Kinnaird Grenadiers and Kinnaird Grenadier Guards with state visits and other important events.

8th Battalion, Royal Arcerion Regiment

• W Company (Arcerion Rifles)
• X Company (Moorden Lowland Rifles)

9th Battalion, Royal Arcerion Regiment
