Companion cavalry would ride the best horses, and receive the best weaponry available. In Alexander's day, each carried a xyston (long thrusting spear), and wore a bronze muscle cuirass or linothorax, shoulder guards and Boeotian helmets, but bore no shield. A kopis (curved slashing sword) or xiphos (cut and thrust sword) was also carried for close combat, should the xyston be lost or broken.
