No. They use blanks.
For gun salutes ( a "gun" in military terms is a cannon), Major Generals and Rear Admirals rate a 13-gun salute. Above that, the salutes are: 15 for Lt. Generals and Vice Admirals 17 for Admirals, Generals, Undersecretaries, Governor Generals of territories, etc., 19 for Vice Presidents, Chiefs of Staff, Speaker of the House, Prime Minisiters, Ambassadors, or those of equal rank. 21 gun salutes are reserved only for Presidents and other heads of state, both current and former.
Well of course different countries' salutes vary. But as for the US there is the hand salute and gun salute. Gun Salutes are rendered as an honor for example, the arrival and departure of a President or the death of a President.
Depends on the country, but in the US, a 21 gun salute is reserved for the flag, the President, or foreign heads of state. 17 gun salutes are for head of Senate/House, general of the army, fleet admiral, and a lot of other high level officials.
Passing honors, side honors, gun salutes
Salutes performed by firing guns ranks from a low of 5 guns, to the highest possible salute- 21 guns. A "21 gun salute" is paying the greatest tribute possible to the person or persons being saluted.

Originally, if a warship fired a seven-gun salute, a fort would typically return a 21-gun salute. The 21-gun salute is the highest honor and is traditionally reserved for national flags and heads of state, while the seven-gun salute is often used for certain military honors. The practice of gun salutes symbolizes respect and acknowledgment between military forces.
