Capturing thralls is part of the Ironborn reaving tradition, and the Ironborn Trappers excel at bringing enemies in alive. Trappers are not built for the front lines, but rather for flanking and hindering heavier enemy units with their long, barbed spears and entangling nets. With Trappers on one side and virtually any other unit on the other, even the most heavily armored knights will find themselves overwhelmed and defeated in short order. That said, Trappers are not suited to protracted engagements, and fall easy prey to long-range archery.
