A guard of honour (GB), also honor guard (US), also ceremonial guard, is a guard, usually military in nature, appointed to receive or guard a head of state or other dignitaries, the fallen in war, or to attend at state ceremonials, especially funerals. In military weddings, especially those of commissioned officers, a guard, composed usually of service members of the same branch, form the Saber arch. In principle any military unit could act as a guard of honour. However, in some countries certain units are specially designated to serve as a guard of honour, as well as other public duties.
