For the Ill Bethisad timeline, I came up with systems for all 3 constituents nations of the Federated Kingdoms, a loose stand-in for the United Kingdom that contain Scotland, England and Cambria (Wales).
Each nations has its own distinct army and traditions so I wanted their insignias to reflect this but at the same time I wanted someone from our timeline to recognise them all as british.
The first is for the Kingdom of Cambria which is based on the royal navy with the enlisted using chevrons and bars which I felt complimented the cuff rings.
