The Florida National Guard, like those of other states, provides trained and equipped units for prompt mobilization in case of war or national emergency. Guardsmen may take part in functions ranging from limited actions in non-emergency situations to full-scale law enforcement (martial law) in cases when the governor determines that ordinary law enforcement officials can no longer maintain civil control. The state mission assigned to the National Guard is "to provide trained and disciplined forces for domestic emergencies or as otherwise provided by state law." The Florida National Guard serves as the state's "defense force."
