A guard of honour is a ceremonial event practised in the military and sports throughout the Commonwealth of Nations as a mark of respect.
In the military in countries of the Commonwealth of Nations, a guard of honour is a ceremonial practice to honour domestic or foreign dignitaries, the fallen in war, or a ceremony for public figures who have died. In military weddings, especially those of commissioned officers, a guard, comprising usually of service members of the same branch, form the Saber arch.
A guard of honour is formed to present formal ceremonial compliments to royal or presidential dignitaries by a guard not exceeding 100 personnel (including three officers, one with a colour) with other particular distinguished individuals saluted by a guard not exceeding 50 personnel. A half guard is a colloquial term describing a guard of honour of not more than 50 personnel (including two officers, one with a colour). A guard of honour could have a single service contingent (e.g. army) or it could be a tri service (inter-service) affair. The guard commander, after saluting the dignitary (usually head of state), marches up to him or her and escorts him or her to inspect the guard (soldiers in formation). During the salute, the national anthems of both the dignitary's country and the host country are usually played by a ceremonial band.
Only a standard, guidon, Queen's Colour, or a banner presented by either a member of the Royal Family or the governor-general may be carried by a royal guard of honour. Only a regimental colour or a banner presented by a personage other than a member of the Royal Family may be carried on a half guard of honour. A smaller unit honouring distinguished visitors at a military installation is known as a quarter guard. The commander is three paces in front of the second file from the right and accompanies the personage for whom the guard is mounted. An officer carrying the Colour stands three paces in front of the centre; if there is a third officer he will be three paces in front of the second file from the other flank.
The tri-service Federation Guard, consisting of members of the Australian Army, the Royal Australian Air Force and the Royal Australian Navy provides guards of honour for various ceremonies. All members of the guard are enlisted in their respective areas before volunteering for service in the guard. The rifle of choice is the L1A1 SLR.
