Ancient Greek warfare and slingers ("sfendonitai") while archers ("toxotai") were rare, mainly from Crete, or mercenary non-Greek tribes (as at the crucial battle of Plataea 479 B.C.) Greek armies gradually downgraded the armor of the hoplites (to linen padded thorax and open helmets) to make the phalanx more flexible and upgraded the javelineers to lightly armored general purpose infantry ("thorakitai" and "thyreophoroi") with javelins and sometimes spears. Eventually, these types effectively complemented the Macedonian style phalanx which prevailed throughout Greece after Alexander the Great. Cavalry had always existed in Greek armies of the classical era but the cost of horses made it far
Thracian warfare (plus the onset of winter) meant that this army only held together for about six weeks and any Thracian conquests were ephemeral. The Sapaeans ruled Thrace after the Odrysians until its incorporation to the Roman Empire as a province. Thrace became a Client state of Rome at 11 BC and was annexed at 46 AD. Thrace had the potential to muster a huge number of troops though this rarely occurred. By tradition, Thracians honored warriors and, according to Herodotus, despised all other occupations. The Thracians fought as peltasts using javelins and crescent or round wicker shields called "peltes". Missile weapons
