His shield

Hoplite was an armoured warrior. A light infantryman was a Peltast.

A peltast was a light infantryman, unarmoured, equipped with crescent shaped shield and javelins, used to harrass armoured infantry formations and archers, and as well fill the gap between armoured infantry formations and their flanking cavalry. They were mainly hired from the tribesmen of Thrace.

Peltasts is the English form of the Greek plural πελτασται ( usually transliterated peltastae ), "shield bearers."
