Guards Machine Gun Regiment

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".

The Household Battalion was an infantry battalion of the British army during the Great War. It was formed in September 1916 from the reserves of the Household Cavalry regiments to help fill the every-increasing demands for infantry on the Western Front. Considerable effort was expended in the conversion of cavalrymen into footsoldiers trained and equipped for trench warfare. The battalion spent its entire existence on the Western Front as part of the 4th Infantry Division, arriving as the Battle of the Somme was ending in early December 1916. It fought in the Battle of Arras and later at Third Ypres, suffering severely in the assault on Poelcappelle. Its last major engagement was the defence of Bourlon Ridge during the Battle of Cambrai in late 1917. By this time, it had become apparent that there were insufficient reserves to support all the Household Cavalry regiments that had been converted to infantry and it was disbanded as part of a general reorganization in February 1918.
