Schiltron

A schiltron (also spelled sheltron, sceld-trome, schiltrom, or shiltron) is a compact body of troops forming a battle array, shield wall or phalanx. The term is most often associated with Scottish pike formations during the Wars of Scottish Independence in the late 13th and early 14th centuries.
