Fleet Expeditionary (Tiperyn)

The Fleet Marine Corps (: 𐍆𐌻𐍉𐌰𐍄𐌼𐌰𐍂𐌹𐌽𐌹𐌴𐍂𐍃𐌺𐍉𐍂𐍀𐍃, tr. Floatmarinierskorps), also known as the Tiperyn Marines, is a corps of the Realm Armada and the primary and  arm of the Tiperyn Realm Defence.

Although the Fleet Marine Corps is the junior and smaller of Tiperyn's two branches after the Realm Guard, it has been considered Tiperyn's principle expeditionary land force since the Great Kesh War. This has been due to its ability to deploy battalion- and brigade-size formations independently of the other branches, as an arm of the Realm Armada. In addition, the Fleet Marine Corps is considered to be a federal force under the command of the Admiralty Board, whose leader—Cardinal of the Fleet—is a cabinet-level position. Meanwhile, the Realm Guard's regiments are under the administration of Tiperyn's duchies and principalities, introducing political challenges and rivalries to the branch. Thus, the development of the Fleet Marine Corps' doctrine and force structure has been faster than the Realm Guard, and its logistics and manning is more consistent throughout the branch.

The Fleet Marine Corps is a combined arms force, manning its own infantry, armor, artillery, cyber, and support units. The cores of the Fleet Marine Corps is its Marine Strike Brigades, which are able to rapidly deploy a reinforced battalion within 18 hours amphibiously anywhere in the world and the remainder of the brigade via air within 36 hours. It is the largest land formation within the Realm Defence under the corps-level, as the next largest formation is the regiment, which the remainder of the Fleet Marine Corps and Realm Guard are organized into.

The lineage of the Fleet Marine Corps harks back to the Realm Armada's use of dedicated sailors as, , and makeshift landing forces dating back to its 1345 formation. The branch was formally founded on 20 February 1882 as a subdivision of the Realm Armada, and given its own representative on the Admiralty Board—now the Chief of Expeditionary Operations). The Fleet Marine Corps has fought in every war Tiperyn has been engaged in since its formation, with the most recent being the Naseri Civil War that began shortly after the Great Kesh War.

Leadership
The Fleet Marine Corps is completely subordinate to the Realm Armada in terms of organization. However, the Chief of Expeditionary Operations is considered to be the senior officer of the Fleet Marine Corps and is typically filled by a Vice Admiral as one of the Realm Armada's limited number of service branch Vice Admirals. The Chief of Expeditionary Operations, a Major Admiral billet colloquially referred to as the Captain General, originating during the Grand Campaigns when the Chief of Expeditionary Operations first operated in a tactical and operational capacity equivalent to that of a Realm Guard corps commander.

The Captain General is the highest ranking officer in the Fleet Marine Corps. Although Fleet Marine Corps Vice Admirals are eligible to be appointed to serve as the Cardinal of the Fleet—the highest ranking officer in the Realm Armada and the naval branches' only Admiral billet—by the Empress, this has never occurred in the Realm Armada's history. In such a scenario, the Captain General would remain the ranking marine officer, as Fleet Cardinals forfeit their original branch affiliation during their service as Cardinal.

The Captain General maintains their own command staff, which includes the Vice Chief of Expeditionary Operations (colloquially referred to as the Captain Lieutenant) and the Chief Warrant Officer of the Fleet Marine Corps (the branch's senior enlisted man). This staff heads the remainder of the Fleet Marine Corps headquarters, which includes several dozen subordinate offices. Examples include the Offices of Logistics, Manpower, Intelligence, Operations, and Public Affairs.

The current Captain General is Vice Admiral Jakob Richter aided by Captain Lieutenant Major Admiral Gerit Dokkum and Chief Warrant Officer Jesca Tresoar. The Captain General reports to Cardinal of the Fleet Admiral Katherine Rijnder.

Organization
The Fleet Marine Corps' operational maneuver units are typically under the command and control of one of the Realm Armada's Expeditionary Corps. Each of the High Seas Fleet's two sea and two ocean divisions contains an Expeditionary Corps responsible for the employment of marine forces and the coordination between them and naval sea and air assets. Each Expeditionary Corps is under the command of a Major Admiral who reports to the Vice Admiral in command of the sea or ocean division. However, one of the service's Strike Brigades is under the direct authority of the Captain General and his headquarters independent of the expeditionary corps and navy divisional structure.
