Nope. That's a different animal entirely.BarryLee said:
A 21-gun salute is the most commonly recognized of the customary gun salutes that are performed by the firing of cannons or artillery as a military honor.
... As naval customs evolved, 21 guns came to be fired for heads of state, or in exceptional circumstances for head of government, with the number decreasing with the rank of the recipient of the honor.
A gun salute is not to be confused with the three-volley salute often rendered at military funerals.
