Strictly speaking, centaurs are a type of cavalry; under heavy armor, they can charge on a large scale, and almost no one of the same rank can withstand them. Unfortunately, they met the Naga, a race with almost no weaknesses.
Their bodies, snake-like, appear frail at first glance, but in reality, both their constitution and strength are exceptionally strong, and their evasion abilities are a notch higher than those of their peers.
Especially in terms of on-the-spot evasion.
With their human torsos and serpentine tails, the thick tails support their bodies. When impacted, a bend or a collapse allows them to dissipate some of the force of the blow. Their several-meter-long tails stretched out on the ground are like stumbling blocks to the charging cavalry. Once hit, they'd fall and get thrown off balance.
The centaurs who charged from behind were immediately brought down, leaving the others no choice but to stop and fight the Nagas head-on with swords drawn.
