Guard mounting is a ceremonial procedure in which a new group of guards replaces the outgoing guards at a military or ceremonial post. This event often includes a formal inspection and a change of duty, ensuring that the new guards are prepared and properly equipped for their responsibilities. During guard mounting, the outgoing guards typically present arms and salute, while the incoming guards are inspected by a commanding officer. This tradition is common in many military organizations, including the British Army and United States Armed Forces, and serves to maintain discipline and honor within the ranks.
