the military leader and theorist Võ Nguyên Giáp. Giap's People's War, People's Army closely followed the Maoist three-stage approach but with greater emphasis on flexible shifting between mobile and guerrilla warfare, and opportunities for a spontaneous "general uprising" of the masses, in conjunction with guerrilla forces. Organization Guerrilla organization can range from small local rebel groups with a few dozen participants to tens of thousands of fighters, deploying from tiny cells to formations of regimental strength. In most cases, there is a leadership aiming for a clear political objective. The organization is typically structured into political and military wings, sometimes allowing the political leadership plausible deniability of military attacks. The most fully elaborated guerrilla warfare structure was seen by the Chinese and Vietnamese communists during the revolutionary wars of East and Southeast Asia. A simplified example of this more sophisticated organizational type, which was used by revolutionary forces during the Vietnam War, is shown below. Types of operations Guerrilla operations typically include a variety of attacks on transportation routes, individual groups of police or military, installations and structures, economic enterprises, and targeted civilians. Attacking in small groups and using camouflage and often captured weapons of that enemy, the guerrilla force can constantly keep pressure on its foes and diminish its numbers and still allow escape with relatively few casualties. The intention of such attacks is only military but also political in aiming to demoralize target populations or governments or by goading an overreaction that forces the population to take sides for or against the guerrillas. Examples range from chopping off limbs in various internal African rebellions to the suicide bombings of Palestine and Sri Lanka to sophisticated maneuvers by Viet Cong and NVA forces against military bases and formations. Surprise and intelligence For successful operations, surprise must be achieved by guerrillas. If the operation has been betrayed or compromised, it is usually called off immediately. Intelligence is also extremely important, and detailed knowledge of the target's dispositions, weaponry, and morale is gathered before any attack. Intelligence can be harvested in several ways. Collaborators and sympathizers usually provide a steady flow of useful information. If working clandestinely, guerrilla operatives may disguise their membership in the insurgent operation and use deception to ferret out needed data. Employment or enrollment as a student may be undertaken near the target zone, community organizations may be infiltrated, and even romantic relationships struck up in intelligence
