A "21-Gun Salute" is a traditional military honor that involves firing cannons or artillery in a specific sequence. It is often used to commemorate significant events, such as national holidays, the arrival of foreign dignitaries, or the death of a prominent leader. The number 21 is significant, as it is considered a symbol of respect and is the highest number of gun salutes typically used. This ceremonial practice dates back to the 14th century and has roots in naval traditions. The salute is performed by a military unit and is recognized internationally, with variations in the number of guns fired depending on the occasion and the rank of the individual being honored, such as a head of state or a member of royalty.
