New generation warfare or NGW (Russian: 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.
