Asymmetrical warfare refers to conflicts where opposing forces differ significantly in military capabilities and strategies. Typically, one side is a conventional military force, while the other may be a smaller, irregular group using unconventional tactics. This type of warfare often involves guerrilla tactics, sabotage, and psychological operations to exploit the weaknesses of the stronger opponent. In asymmetrical warfare, the weaker side aims to level the playing field by using surprise, mobility, and knowledge of the local terrain. Examples include the tactics used by groups like the Taliban against NATO forces or the Viet Cong during the Vietnam War.
