In 2007 Frank G. Hoffman conducted a study on the new threats that the U.S. Marines could face in the near future. The study resulted in the creation of the hybrid warfare theory.     During the Russian invasion of the Crimea peninsula both media and scholars quickly concluded that the Russian way of conducting the invasion was a new way of warfare and attributed the invasion as hybrid warfare. However, scholars have since then started to criticize the concept of hybrid warfare and its ability to explain the Russian behavior in Crimea and its claim to be a new way of warfare. The purpose of this essay is to examen how new the concept of hybrid warfare is. This is done by examining if Operation Overlord and the Têt Offensive can be understood as hybrid warfare.  The result shows that both Operation Overlord and the Têt Offensive includes most of the attribute in Hoffman´s hybrid warfare theory and therefore can be understood as hybrid warfare. The result also shows that even if the term hybrid warfare is something new the means and methods are not.
