Scale Armor
Armor made of overlapping metal scales
Scale armor consists of small metal scales overlapping like fish scales, attached to a fabric or leather backing. One of the oldest types of metal armor dating back to antiquity, it was used across the ancient world from Rome's lorica squamata to Sassanid Persian variants. While offering both flexibility and protection, its overlapping structure leaves it vulnerable to downward thrusting attacks that can slip between the scales.
