The Republican Marine Regiments (RMR) is a corps of amphibious, combined arms regiments. They are more widely known as Tercios and are officially known in Iverica as Regimientos Tercios dei L'República. The Tercios can trace their origins back to the formation of the Iberic Empire's Tercios Imperialé (Anglish: Imperial Regiment of Thirds). The regiments function as the Republic of Iverica's elite amphibious infantry body. The Regiments not only serve as security for naval vessels but are the premier choice for honour guards in the Iverican government. Thus, all Iverican Embassies and a majority of foreign delegates are attached with a security detail of veteran marines. Given Iverica's geographical conditions and heavy naval focus, the Tercios are known to be one of the best-equipped infantry bodies in the Armed Service. It rivals the Airevieri in terms of cost of training and equipment.

As a broadly warfighting and adaptable elite infantry force, the Tercios are trained for rapid deployment worldwide and capable of dealing with a wide range of threats. The Republican Marine Regiments are organised into three types of units, Expeditionary Corps, Expeditionary Regiments, and Expeditionary Detachments. The three are distinguished by their size in terms of manpower and operate at different scales of warfare.

Each of the unit types is formed from a collection of battalions who number between 300-500 marines. Using the Battalion as their basic unit, marine formations are structured according to their mission. These missions typically include ship security, boarding operations, amphibious assault, counter-piracy, and major ship-to-shore assaults. The Regiments primarily carry out amphibious assault and helicopter-borne operations. Tercio doctrine is heavily focused on Third-Generation and Fourth-Generation strategies and tactics including but not limited to, Manoeuvre warfare, Counter-Insurgency, and Asymmetric warfare. Certain regiments also specialise in special boat operations, raiding operations, or as dedicated special operations forces. The Corps operates in all environments and climates, though particular expertise and training is spent on amphibious warfare, arctic warfare, mountain warfare, expeditionary warfare, and its commitment to the Republic of Iverica's Rapid Reaction Forces which include the regiments of the Exersito's elite Horse Grenadier Divisions.

Throughout its history, the Tercios have seen action in a number of major wars often fighting beside the Iverican Army – including both Argic Wars, the Thalassan War, Vasqqan Civil Wars, Operation Ultra Violet, and many others. Today, the Tercios are structured, trained, and deployed as a highly-deployable, major warfighting force with the ability to conduct special operations on a more limited scale.

Organisation

The Republican Marine Regiments are organised into three types of units, Expeditionary Corps, Expeditionary Regiments, and Expeditionary Detachments. The three are distinguished by their size in terms of manpower and operate at different scales of warfare.

Each of the unit types is formed from a collection of battalions who number between 300-500 marines. Using the Battalion as their basic unit, marine formations are structured according to their mission.

Expeditionary Corps
Structured for major warfighting, a Cuerpos Tercio D'Expediciónare (CTE) may number 18,000-30,000 marines with various armoured and aerial assets in support. In this capacity, the Corps is capable of advancing well within terrestrial boundaries and confronting major warfighting enemy units in division strength. As of 2019, the Corps designation mainly serves administrative purposes for managing and re-deploying its constituent regiments through the authority of a Comandante dei Cuerpo (OF-8). As no major engagement has required the full deployment of a major warfighting force in recent years, Corps headquarters have been administering the tasking and organisation of the units under their command.

Expeditionary Regiments
The Regimientos Tercio D'Expediciónare (RTE) are the smallest unit type that guarantees complete combined arms capability. To fulfil this role, a Regiment must be attached with at least minimal aerial, armoured, and electronic warfare assets. On average, marine regiments are far larger than those of the army, composed of 3,000-8,000 marines and commanded by a Comandante dei Regimiento (OF-7), the Regiments are tasked mainly with quick response and deployment to areas of medium or high-intensity combat of an operational scale. Under these parameters, Regiments are typically attached to Carrier Groups and Capital Elements. In a combat theatre, they are expected to be at parity with a brigade-sized force and are trained to respond with asymmetrical warfare if met with overwhelming odds.

Expeditionary Detachments
The Desapeios Tercio D'Expediciónare (DTE) are the smallest unit type capable of limited independent operations. Unlike a Regiment, Detachments are structured to fulfil specific mission requirements with as small a force as possible. This entails that Detachments be equipped only with the necessary equipment and manpower and neither with redundancies nor excessive swing-roles. Commanded by a Comandante dei Desapeio (OF-6) or by a Coronel (OF-5), a Detachment may be between 1,000-2,000 marines strong. This smaller size relegates Detachments to postings as small capital ship complements, handling sector security, seizing time-sensitive objectives, or aggressive reconnoitre in force.
