The wars in the Middle East (Afghanistan and Iraq) in which the United States has been involved are widely debated and often seen as asymmetrically full-scale wars. What is characteristic of these conflicts are that there is no research to map these conflicts regarding the US application of hybrid warfare. The purpose of this study is to gain an understanding of US contemporary warfare by consuming the modern theory of New Generation Warfare (NGW) on the conflicts in Afghanistan in 2001 and Iraq in 2003. The ambition is, therefore, to consuming the existing theoretical starting point to analyse existing research in the field to contribute to the war science research. The conclusions drawn from this study are that US contemporary warfare is moving in the same direction as Russia. It has shown that US contemporary warfare is a precursor to Russian contemporary warfare, which is characterized by military interventions with special operations forces and fewer conventional forces with great emphasis on psychological and information operations. Based on the analysis of the Middle East conflicts in which the United States has been involved.
