First Corps of Cadets (Massachusetts)
The First Corps of Cadets of Massachusetts formed in 1741. Its motto is Monstrat Viam - "It Points the Way." While it has served in several 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. == History == === Early period === Unlike the oldest regiments of the Massachusetts National Guard, which began as standing militia made up of all able-bodied men between the ages of 16 and 60, the First Corps of Cadets, the Commonwealth's and the National Guard's oldest volunteer militia unit, has always consisted of young men, and now women, who volunteered to serve.
