"The Irish Guards (IG), is one of the Foot Guards regiments of the British Army and is part of the Guards Division. Together with the Royal Irish Regiment, it is one of the two Irish infantry regiments in the British Army. The regiment has participated in campaigns in the First World War, the Second World War, the Iraq War and the War in Afghanistan as well as numerous other operations throughout its history. The Irish Guards claim six Victoria Cross recipients, four from the First World War and two from the Second World War.
One way to distinguish between the five regiments of Foot Guards is the spacing of the buttons on their tunics. The Irish Guards have buttons arranged in fours as they were the fourth Foot Guards regiment to be founded. They also have a prominent St. Patrick's blue plume on the right side of their bearskins." - (en.wikipedia.org 25.05.2021)
