Flechette
A flechette fleh-SHET is a pointed steel projectile with a vaned tail for stable flight. The name comes from French fléchette, "little arrow" or "dart", and sometimes retains the acute accent in English: fléchette. They have been used as ballistic weapons since World War I. Delivery systems and methods of launching flechettes vary, from a single shot, to thousands in a single explosive round. The use of flechettes as antipersonnel weapons has been controversial, and is considered by some to be a human rights violation.
