From Echoes from Elsewhere Wiki

Marine Corps Organization

The Duchy Marines are an elite combined-arms planetary assault force. All aviation assets (including dropships) belong exclusively to the Navy. Each Duchy is expected to independently handle a single theater of operations and therefore maintains at least one full Marine Division.

All aviation assets are operated by the Navy. Dropships are heavily armed to survive and fight effectively in contested airspace.

Regimental, Brigade, and Division Headquarters & Support

Regiment (~2,300 Marines total) Includes Regimental HQ staff (~80–100 Marines) sized to command 3 Battalions and the attached Artillery Battery.

Brigade (~7,400 Marines total) Consists of 3 Regiments plus a substantial Brigade HQ and Support element (~800–1,000 Marines). This includes:

  • Brigade Commander (Brigadier General or Colonel)
  • Executive Officer, Operations, Intelligence, Logistics, Communications, and Fire Support Coordination staff
  • Brigade Engineer Battalion, Logistics Battalion, Medical Company (Navy Corpsmen), Intelligence Company, and additional Systems Operators

Division (~16,300 Marines total) Consists of 2 Brigades plus Division HQ and Support (~1,200–1,500 Marines). This includes higher-level command, sustainment, intelligence, and theater-level coordination assets.

Strategic Role

Each Duchy maintains at least one full Marine Division (~16,300 Marines) to independently handle a single theater of operations.

The Brigade is the primary combined-arms maneuver formation. The Division provides the command layer for sustained theater-level operations.
