What or who are citizen militias in the US?

Answer 1

Citizen militias in the U.S. refer to organized groups of private citizens who claim to be prepared to defend their rights and communities, often operating outside of official law enforcement or military structures. They typically advocate for Second Amendment rights and may engage in activities such as training exercises and community patrols. While some militias emphasize a commitment to constitutional principles, others have been associated with extremist ideologies. Their legal status and activities can vary significantly by state and local jurisdiction.
