Trooping the Colour is a ceremony performed by regiments of the British Army. It has been a tradition of British infantry regiments since the 17th century, although its roots go back much earlier. On the battlefield, a regiment's colours, or flags, were used as rallying points. Consequently, regiments would have their ensigns slowly march with their colours between the ranks to enable soldiers to recognise their regiments' colours.
In some militaries, foot guards are senior infantry regiments. Foot guards are commonly responsible for guarding royal families or other state leaders, and they also often perform ceremonial duties accordingly, but at the same time are combat soldiers.
"Other ranks" is the term used to refer to all ranks below officers in the British Army and the Royal Marines. It includes warrant officers, non-commissioned officers ("NCOs") and ordinary soldiers with the rank of private or regimental equivalent. Officers may, in speaking, distinguish themselves from those "in the ranks".
