New generation warfare or NGW (Война нового поколения) is a Russian theory of unconventional warfare which prioritizes the psychological and people-centered aspects over traditional military concerns, and emphasizes a phased approach of non-military influence such that armed conflict, if it arises, is much less costly in human or economic terms for the aggressor than it otherwise would be. It was first enunciated in 2013 by Valery Gerasimov as part of his Gerasimov Doctrine. Numerous analysts cite the 2014 Russian annexation of Crimea and war in Donbas as specific examples that followed the guidelines of new generation warfare. According to one analyst, "the Russian view of modern warfare is based on the idea that the main battlespace is the mind and, as a result, new-generation wars are to be dominated by information and psychological warfare, ... morally and psychologically depressing the enemy’s armed forces personnel and civil population. The main objective is to reduce the necessity for deploying hard military power to the minimum necessary." The term new generation warfare was first introduced in Russian (Война нового поколения) in 2013, as synonyms for grey zone and hybrid warfare in the Gerasimov doctrine. All of terms that refer to modern military theories of warfare that go beyond conventional warfare. The terms began to spread and take on various meanings, and were not always used with clarity. Some analysts use them more or less interchangeably, while others identify differences among them. In his 2009 paper, Frank Hoffman noted the rising use of the term hybrid threat, and analyzed the multiple meanings of the term. Hoffman pointed out that there had been resistance among some analysts for the new term, who preferred older concepts of "conventional" and "irregular" warfare, while Hoffman believed that the older terms were insufficient to describe conflicts in the modern world. He defined hybrid threat as an adversary that "simultaneously and adaptively employs a fused mix of conventional weapons, irregular tactics, terrorism and criminal behavior in the battle space to obtain their political objectives".
