Flechette launchers

Flechette launchers are weapons in Star Wars that use canisters and missiles as ammunition. These canisters and missiles would, upon firing of the weapon, release hundreds of razor sharp flechettes at high speeds in a wide spread.

Anti-personnel flechette canisters are able to eliminate entire squads, and anti-vehicle variants also existed. Because of the wide spread of flechette weapons, they proved to be effective at shooting down airspeeders and repulsor craft that would normally be able to evade enemy fire (citation needed).
