The Thureophoroi were light peltasts in the Hellenistic armies. They wore leather armour, if any, bronze helmets and carried an oval, wooden shield, the thureos, in battle.
They had a lot of heavy javelins, and a short hoplite sword. They were skirmishers and ambushers.
Provided open handed without spears. (The spears in the photo are made from a washing up brush, which means they flex!!)
