In 513BC, around 200 years after the Scythians and Cimmerians invaded Assyria to rescue the majority of the Israelites in 700BC, Darius of Persia invaded Scythia.

This is most likely the continuation of the Sukkalmah Scar Susa Elamite Persians not the Ephraimites.

The Ephraimites and Medes would have been fighting with the Scythians.

That's why Ephraim vs Elam is minimum specificity when discussing Iran, just like Israelites vs Edomites, Israelites vs Jebusites, and Israelites vs Canaanites.

Scythian female warriors used poisoned arrows and gold mirrors on horseback. They won a strategic victory against what is said to be 700k Elamites.

Greeks called these female warriors Amazons, which they mythologised, but they were actually Scythian female warriors.
