Guerrilla tactics refer to unconventional methods used by smaller, less powerful groups to combat larger, more established forces. These tactics often include surprise attacks, ambushes, and sabotage, allowing the weaker party to exploit the vulnerabilities of their opponent. The term originated from the Spanish Guerrilla War in the early 19th century, where small bands of fighters used hit-and-run strategies against invading armies. These tactics are not limited to military contexts; they can also be applied in political activism and business. In marketing, for example, guerrilla tactics involve creative, low-cost strategies to promote a product or idea, aiming to generate maximum impact with minimal resources.
