Note that soldiers supplying their own equipment was a feature of the early Roman Republic (and perhaps the Roman Kingdom, though of course we have no reliable records from that time), not the Roman Empire. By the late Republic (after around 100BC) what are called the Marian reforms had shifted the army from a citizen-militia where soldiers were divided into classes based on wealth (and thus what equipment they could afford) to a more uniform, professionalized force whose equipment was provided by the state and salary paid by the state (or, in some cases, by extremely wealthy individual generals).
