21 or to attack the enemy. One of the most important developments in the field of EW has been the introduction of automated and integrated EW systems, which provide a high degree of information in addition to interception, directionfinding and jamming activities. 2.20 Psychological Warfare. Information is one of the several means to target the human mind. Psychological warfare is achieved through mass media such as newspapers, radio and television broadcasts and distribution of leaflets. The prevailing state of information technology allows effective psychological warfare to be conducted in a very subtle manner. In order to be effective, psychological operations need to be conducted in conjunction with other operations. During peace time and in LIC operations, this effort can be termed as “psychological initiatives”. 2.21 Cyber Warfare. This entails techniques to destroy, degrade, exploit or compromise the enemy’s computer-based systems. Cyber warfare includes exclusive attacks, known as hacking, on enemy computer networks. Computer hacking has evolved to a stage wherein information stored or passing through computer networks is interfered with to degrade the adversary’s C2 structure. 2.22 Economic Information Warfare. This form of warfare uses information as power to destabilise the economy of the adversary. Since all revenue-generating industries of a country such as aviation, transport, power, banking and the like use computer-based systems, IW at the strategic level can play havoc with the national economy of the adversary. 2.23 Network Centric Warfare. NCW focuses on the combat power that can be generated by the effective linking or networking of the war-fighting machinery and organisations. The basic elements necessary to generate the requisite shared battle-space awareness that can be exploited through self-synchronisation to achieve the overall objective are given below: A virtual sensors grid that would provide a ‘grid of capabilities’ overlaying the battle-space instead of •
