For the first time in the history of the National Day Parade, only four 25-pounder guns will be used in the Presidential Gun Salute compared to the traditional half a dozen guns.
The Presidential Gun Salute has been a mainstay of the National Day Parade: 21 shots fired within 3 minutes as a mark of respect to the President when he inspects the contingents in the stadium.
how about that? we only need 1/2 the number of guns, to make the same 21 shots. chalk up another victory for productivity.
