in highly populated areas could have devastating effects on the economy and morale. In contrast, the weaker side may not have these structures at all. Training and tactics and technology can prove decisive and allow a smaller force to overcome a much larger one. For example, for several centuries the Greek hoplite's (heavy infantry) use of phalanx made them far superior to their enemies. The Battle of Thermopylae, which also involved good use of terrain, is a well-known example. If the inferior power is in a position of self-defense; i.e., under attack or occupation, it may be possible to use unconventional tactics, such as hit-and-run and selective battles in which the superior power is weaker, as an effective means of harassment without violating the laws of war. Perhaps the classical historical examples of this doctrine may be found in the American Revolutionary War, movements in World War II, such as the French Resistance and Soviet and Yugoslav partisans. Against democratic aggressor nations, this strategy can be used to play on the electorate's patience with the conflict (as in the Vietnam War, and others since) provoking protests, and consequent disputes among elected legislators. If the inferior power is in an aggressive position, however, and/or turns to tactics prohibited by the laws of war (jus in bello), its success depends on the superior power's refraining from like tactics. For example, the law of land warfare prohibits the use of a flag of truce or clearly marked medical vehicles as cover for an attack or ambush. Still, an asymmetric combatant using this prohibited tactic to its advantage depends on the superior power's obedience to the corresponding law. Similarly, laws of warfare prohibit combatants from using civilian settlements, populations or facilities as military bases, but when an inferior power uses this tactic, it depends on the premise that the superior power will respect the law that the other is violating, and will not attack that civilian target, or if they do the propaganda advantage will outweigh the material loss. Terrorism There are two different viewpoints on the relationship between asymmetric warfare and terrorism. In the modern context, asymmetric warfare is increasingly considered a component of fourth generation warfare. When practiced outside the laws of war, it is often defined as terrorism, though rarely by its practitioners or their supporters. The other view is that asymmetric warfare, does not coincide with terrorism. Use of terrain
