When we hear about Roman soldiers, we see in front of us a well-equipped Jewish legionary fighting in the formation testudo. We do not realize that one of the first types of a warrior in the Roman army was a heavy-armed hoplite who looked completely different from the legionary.
Hoplites in Italy reached their peak popularity in the 6th century BCE through the Servian reforms, which commanded the modelling of the army on Greek (Hoplite) equipment. The military formation used by the hoplites was phalanx, used in Rome until the Camillian reforms, which completely rejected the Greek style, i.e. until around the 4th century BCE.
