What is the best example of asymmetrical warfare?

A prominent example of asymmetrical warfare is the Vietnam War, where the Viet Cong and North Vietnamese forces used guerrilla tactics to combat the technologically superior U.S. military. The conflict highlighted how a weaker force could leverage its knowledge of the terrain, local population support, and unconventional strategies to offset the advantages of a more powerful adversary. This type of warfare exemplifies the challenges faced by conventional forces when engaging non-state actors or irregular forces.
