Why is "Byzantine battle tactics" trending?

Wikipedia Overview

The Byzantine army evolved from that of the late Roman period taking as leading models and shaping itself on the late Hellenistic armies, but it became considerably more sophisticated in strategy, tactics and organization. The language of the army was still Latin, although later Greek dominated, as it became the official language of the entire empire. Unlike the Roman legions, its strength was in its cavalry, especially the armoured cataphracts, which evolved from the clibanarii of the late empire. Infantry were still used but mainly as a base of maneuver for the cavalry, as well as in specialized roles. Most of the foot-soldiers of the empire were the armoured skutatoi and later on, kontarioi, with the remainder being the light infantry and archers of the psiloi. The Byzantines valued intelligence and discipline in their soldiers far more than bravery or brawn. The "Ρωμαίοι στρατιώται"(rōmaíoi stratiōtai) were a loyal force composed of citizens willing to fight to defend their homes and their state to the death, augmented by mercenaries. The training was very much like that of the legionaries, with the soldiers taught close combat techniques with their swords, spears and axes, along with the extensive practice of archery.
