Marines (Valhallan)

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.

• Dorsal and Ventral 60 kJ semi-autonomous turrets (25 mm equivalent) – anti-drone and anti-personnel defense
• One 120 kJ turret on each stubby wing – heavy ground attack during CAS runs

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

Regimental Headquarters & Support

A Regiment includes a dedicated Regimental HQ element sized to command and control its three Battalions plus the attached Regimental Artillery Battery. This HQ provides:

• Regimental Commander (Colonel)
• Executive Officer (Lieutenant Colonel)
• Operations Officer (Major)
• Intelligence Officer (Major)
• Logistics Officer (Major)
• Communications / Systems Officer
• Senior Systems Operators
• Fire Support Coordination Cell (to manage artillery and Navy dropship CAS)
• Additional Navy Corpsmen, maintenance, and administrative personnel

Total Regimental HQ strength is approximately 80–100 Marines, bringing the full Regiment strength to roughly **2,300–2,300 Marines** (including the Artillery Battery).

Strategic Role

Each Duchy maintains at least one full Marine Division (13,122 Marines) to independently handle a single theater of operations.

• A Brigade (6,561 Marines) is the primary combined-arms maneuver formation, consisting of 3 Regiments plus Brigade-level armored, reconnaissance, engineer, and logistics assets.
• A Division consists of 2 Brigades plus Division-level command, support, and sustainment elements.
