This book looks at the use of improvised antiaircraft weapons against enemy planes. Since the very first use of balloons to assist armies in the field air defense weapons have been improvised to bring down the enemy. This has been a common practice during the 20th century, when the use of aircraft came into its own and their role in counterinsurgency necessitated the need for an answer to airpower. This book covers both the weapons and tactics used by insurgents. Guerrilla Air Defense includes illustrations.
