Sabotage, a form of political warfare, varies from highly technical coup de main acts that require detailed planning and the use of specially trained operatives, to innumerable simple acts which the ordinary individual citizen-saboteur can perform. Simple sabotage is carried out in such a way as to involve a minimum danger of injury, detection, and reprisal. There are two main methods of sabotage; physical destruction and the "human element." While physical destruction as a method is self-explanatory, its targets are nuanced, reflecting objects to which the saboteur has normal and inconspicuous access in everyday life. The "human element" is based on universal opportunities to make faulty decisions, to adopt a non-cooperative attitude, and to induce others to follow suit.
