fourth front

is the idea that, in warfare, in addition to land, sea and air, 'cinema', as a new front of attack and defense, comes to supplement, and perhaps even dominate.

In this context Virilio identifies the existence of a 'fourth front' in the waging of warfare, that is to say, a new front of attack and defence which comes to supplement, and perhaps even dominate, the first three attack fronts of land, sea and air. The symbiosis of industrial war and cinema which begins with the First World War, and which is then developed in the Second, leads to the systematic opening up of this fourth front in modern and contemporary warfare. p.84
