How was the Persian army organized?

The Persian army was divided into 2 types: cavalry and infantry. The most important branch of the armed forces was the heavy cavalry. She was called upon to deliver crushing blows to the enemy. She served in the heavy cavalry mainly to know, since few could buy and maintain the weapons of a cataphract (heavy cavalry). Next came the light cavalry, whose task was to weaken the enemy with a hail of arrows and sudden attacks. The infantry had a supporting role. The main weapon for the Persians is the bow. Elephants were also sometimes used.
