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.
