War's original speed upgrade: soldiers who paid extra for legs that weren't their own.

means Troops who fight while mounted on horses (or, in modern militaries, in fast armored vehicles).

from From French cavalerie, from Italian cavalleria, built on cavallo 'horse' — straight back to Latin caballus, a plain workhorse (not the grander equus). The same root gives us 'chivalry,' since a knight's virtue and his horse were once inseparable — one word for the animal quietly split into the soldier, the gentleman, and the whole code of conduct that rode in on its back.
