Spearmans with javelins?

[Atrik]

Just realized that the Seleucids spears actor hold javelins, is it on purpose? Looks a bit weird.

The thyreophoroi or thureophoroi (Greek: θυρεοφόροι; sg.: thureophoros/thyreophoros, θυρεοφόρος) were a type of infantry soldier, common in the 3rd to 1st centuries BC, who carried a large oval shield called a thyreos which had a type of metal strip boss and a central spine. They were armed with a long thrusting spear, javelins and a sword. They also usually wore an iron or bronze Macedonian helmet.
