Olympic Skeet is a variant of skeet shooting, and the specific variant used in the Olympic Games. The discipline is sanctioned by the International Shooting Sport Federation. Two throwing machines at different heights launch a series of 25 targets in a specific order, some as singles and some as doubles, with the shooter having a fixed position between them. Both men's and women's competitions consist of five such series. The top six competitors shoot an additional series as a final round, on targets filled with special powder to show hits more clearly to the audience.
