Unconventional warfare

Unconventional warfare (also known as guerrilla warfare) is when groups of people fight without conventional weapons, like guns and bombs, and without a typical fighting structure like an army or navy. Instead of being led by officers, the groups of people might be led by a leader or leaders who are like teachers or mentors. Instead of using guns and bombs, unconventional warfare might use strategies like sabotage, ambush, and psychological warfare to create confusion and cause the enemy to lose. Unconventional warfare is usually used to fight against a larger and more powerful enemy, like an occupying army or a military.
