Warfare has taken place in different operating environments—domains. Those have traditionally been the geographical spaces where contact with the enemy occurs, namely land, sea, air, outer space, and, more recently, information and cyberspace. Cyber warfare, information warfare, electronic warfare, command and control warfare, spectrum warfare, and cognitive warfare are only some designations by which researchers and military experts describe their offensive and defensive non-kinetic actions. The reason for the diversity of the non-kinetic environment is the evolution of the military Electromagnetic Spectrum (EMS) and digital environment over 100 years. With the arrival of radio in the early twentieth century, the militarization of the electronic operating environment began. The latest expansion is the formation of cyberspace. The new capacities of armed forces create new possibilities, both the kinetic and non-kinetic use of force in battlespace. Also, the definitions vary significantly. There are differences between the USA, Russia, China, and NATO. Western countries talk about cyberspace, while Russia and China talk about the information environment/space. This chapter addresses the non-kinetic battlespace operations of electronic warfare, information warfare, cyber warfare, and cognitive warfare, which are key domains in a Non-Kinetic Warfare (NKW) environment. These advanced and new capabilities form a whole new non-kinetic environment in which they become game changers in battle space.
