Counterinsurgency

State action against irregular forces, blending military and political means.

Counterinsurgency

Counterinsurgency (COIN) is the totality of actions aimed at defeating irregular forces, encompassing military, political, economic, psychological, and civic measures. The Oxford English Dictionary defines it as any military or political action taken against guerrillas or revolutionaries, often considered war by a state against a non-state adversary. Insurgency and counterinsurgency campaigns have been waged since ancient history, with Western thought on 'small wars' gaining interest during European colonization and modern thinking developing during decolonization.

Lore & Background

Counterinsurgency theory has been shaped by several key thinkers. The third Marques of Santa Cruz de Marcenado (1684–1732) wrote Reflexiones Militares (1726–1730), discussing early signs of insurgency, prevention, and countermeasures. He recognized that insurgencies usually stem from real grievances, advocating clemency and good governance to win the people's 'heart and love'. General Thomas-Robert Bugeaud, who served in the French conquest of Algeria and the Peninsular War, wrote extensively on Algeria. His methods were 'enemy centric', favoring punitive raids (razzias) by light mobile forces, often targeting subsistence agriculture, and were less discriminatory between civilian and military targets.

Reader's Guide

Counterinsurgency's significance lies in its evolution from ancient practice to modern doctrine, addressing the challenge of non-state adversaries. The theorists highlighted—Santa Cruz de Marcenado, Bugeaud, Liddell Hart, and Galula—represent different eras and approaches, from early recognition of grievances to enemy-centric punitive methods and population-centric strategies. The concept of 'gaps' exploited by insurgents, and the distinction between Maoist and post-Maoist insurgency (per John Mackinlay), show its adaptation to changing conflict dynamics. Counterinsurgency remains relevant as states confront irregular forces, balancing military force with political, economic, and psychological actions. Its legacy includes both successful campaigns (e.g., Malayan Emergency) and failures, underscoring the critical role of popular support and the blurred line between civilians and combatants.
