The United KingdomThe British Lieutenant and Ensign shared the same shoulder epaulettes and the Captain is denoted by his tassels being thicker then the Lieutenant and Ensign's ones. The Company officer ones are not for all regiments, many had different versions due to different facings or other reasons. Some regiments has silver officer epaulettes.
Many Regiment used silver epaulettes instead of gold. Why they did I have no idea.
There was also a Colour Sergeant for Rifles.
Contrary to the belief of most people on here Staff Corporal and such where ranks only used by the horse gurads. Sergeant and such was used by most Cavalry regiments
