Moving beyond the focus on violence against women and violence committed by women, this article interrogates violence countered by women. The article sheds new light on the gendered practices of counterinsurgency in northeast Nigeria, with critical attention to why women joined the civilian resistance to the Boko Haram insurgency and their complex role and agency as local security providers. Using the voices and lifeworlds of women who joined the Civilian Joint Task Force (yan gora) in Borno State as well as the Vigilante Group Nigeria and Hunters Association (kungiya marhaba) in Adamawa State, the article underscores the layered and gender-bending role of women as frontline fighters, knowledge brokers, state informants, and producers of vigilante technologies. The article finds that women counterinsurgents mobilized after Boko Haram shifted its strategy toward using female insurgents, especially as suicide bombers. Women joined the war against Boko Haram for complex reasons, including personal loss, revenge, family ties, community attachment, patriotism, and a collective yearning for normalcy.
