What military tactic is named after the Parthian archers who feigned retreat?

The military tactic named after the Parthian archers who feigned retreat is the Parthian shot.

Parthian horse archers could ride away from an enemy while twisting in the saddle to fire backward with composite bows. The apparent retreat encouraged opponents to pursue, exposing them to renewed missile fire. The maneuver demanded exceptional balance, horsemanship, and archery skill.

The tactic became especially famous after the Parthians defeated the Roman army under Marcus Licinius Crassus at Carrhae in 53 BCE. It was not exclusive to Parthians: related techniques were used by Scythians, Sarmatians, Huns, Turks, Hungarians, and Mongols. A phalanx was a dense infantry formation, while an ambush depends on surprise rather than a mounted feigned retreat.

“Parthian shot” also developed a figurative meaning: a sharp or barbed remark delivered as someone departs.
