The term Non-Associators was applied to American colonists who refused to support and sign "military association" charters.
During the American Revolutionary War, some associator units were said to operate more like, or were in fact loose-knit criminal gangs, taking advantage of the disruption of warfare.

Loyalist Associators often served in mixed-race units, composed of whites, escaped slaves, and even American Indians.
