Shields of the Athenian Marines?

[Sean Manning]

Athenian marines in the age of Thucydides were hoplites and archers, and to a 5th century Greek a hoplite was someone with an aspis, so I would want evidence before believing that marines carried a spare shield each. That said, we don't know a great deal about shipboard combat or the equipment of pre-Roman marines.

There is an argument that Iphicrates' peltast kit was influenced by the equipment of ἐπιβάται, but that is much later.
