The light cavalry of the Komnenian army consisted of horse-archers. There were two distinct forms of horse-archer: the lightly equipped skirmisher and the heavier, often armoured, bow-armed cavalryman who shot from disciplined ranks. The native Byzantine horse-archer was of the latter type. They shot arrows by command from, often static, ranks and offered a mobile concentration of missile fire on the battlefield.[90] The native horse-archer had declined in numbers and importance by the Komnenian period, being largely replaced by soldiers of foreign origins.[91] Turks from the Seljuk and Danishmend realms of central and eastern Anatolia, and those Byzantinised Turks and Magyars settled within the empire, such as the Vardariots, supplied the bulk of the heavy horse-archers of the Komnenian army. Towards the end of the period Alans were also supplying this type of cavalry. Such horse archers were often highly disciplined. The Byzantine horse-archers (termed doryphoroi indicating guard status) at Sozopolis in 1120 performed a feigned flight manoeuvre, always demanding the greatest self-confidence and discipline, which led to the taking of the city from the Turks.[92] Given that they were usually armoured, even if it was comparatively light armour, this type of horse-archer also had the capability to fight with melee weapons in close combat. Skirmish horse-archers, usually unarmoured, were supplied by the Turkic Pechenegs, Cumans and Uzes of the steppes.[93] These troops were ideal scouts and were adept at harassment tactics. They usually attacked as a swarm and were very difficult for a more heavily equipped enemy to bring into close combat. Light horse-archers were also effective as a screening force, preventing an enemy discerning the dispositions of other troops (for example at the Battle of Sirmium).
