The 211th Military Police Battalion ("First Corps of Cadets") is a unit of the Massachusetts Army National Guard. Its Headquarters and Headquarters Detachment is descended from the First Corps of Cadets, initially formed in 1741. Its motto is Monstrat Viam – "It Points the Way." While it has served in five wars, the sub-unit's primary contribution to Massachusetts and to the United States was as an officer-producing institution for new regiments from the Revolutionary War through World War II.
