What term refers to Greek citizen-soldiers who supplied their own armor and weaponry?

The term that refers to Greek citizen-soldiers who supplied their own armor and weaponry is "Hoplites." Hoplites were primarily infantry soldiers in ancient Greece, known for their distinctive equipment which included a round shield (hoplon), a spear, and bronze armor. The concept of the hoplite was central to Greek military organization and warfare, particularly in the 7th to 4th centuries BCE.

Hoplites were typically members of the middle class, owning the necessary armor and weapons required for battle. Their ability to afford these items meant that they were citizen-soldiers, fighting for their city-states (poleis) while also representing their own interests. This made them crucial to the military forces of various Greek city-states, particularly during the formation of the phalanx, a military formation that emphasized tight ranks and coordinated movement.

The other terms provided do not denote the same level of individual responsibility for equipment or citizenship. Peltasts, for instance, were light infantry skirmishers who carried smaller shields and less armor, while Spartiates referred specifically to the elite warrior class of Sparta. Phalanxes describe the military formation made up of hoplites but do not refer specifically to the soldiers themselves
