Hoplitai Haploi are levies drawn from cities and thrust into battle with a little training.
The poorest citizens of the Hellenic and Makedonian poleis fought as a militia roughly organized along the lines of other, more professional hoplite soldiers. They are organized in the phalanx and are quite high quality for militia, due to the dogged Hellenic spirit and fighting tradition. They can be expected to hold a line against most light and medium infantry, though they will be devastated by missile troops, as they have virtually no protection from missiles aside from their shields and the bodies of their compatriots. They are still useful against cavalry as no horse will willingly charge a bristling wall of spear points. Hoplitai Haploi, if used properly, can be an inexpensive and very valuable unit. And though they will be outclassed against heavier and more professional troops, they can, if well supported, hold the line far better than one would expect of a militia.
Historically, the poorest citizens of any polis and the peasants on the estates of Makedonia were called up in defense of their homeland to fight as militia. They had been used to devastating effect in many ancient battles while forming the second line of battle. They were good and courageous soldiers that fought with a degree of discipline and courage that would not be thought possible of an unprofessional milita. They were not cowards and did not break quickly, but were often annihilated if facing good missile troops or heavier, more professional infantry. Peltastai and other units armed with javelins were particularly devastating to the militia hoplites, due to their lack of protection on the battlefield.
