This final paper briefly describes the circumstances that led to the outbreak of World War II and the Homeland War. Then, the operations that preceded the operation "Fall gelb" and the operation "Storm" were briefly described chronologically, with the aim of understanding the strategic position of the armies and states that attacked. The history of Blitzkrieg, which developed between the two world wars and culminated in World War II in the German conquests of Europe, is then described. A modern variant of this Blitzkrieg was shown in Operation Storm with an emphasis on breaking through the Dinara. The Blitzkrieg doctrine and the five main factors on which this tactic is based are defined, with an emphasis on the main factor - the deception factor. After that, the operation of penetration through the Ardennes, ie the German attack on France, was described in detail, and the operation "Storm" was described. In these operations, attention is focused on deception, shown by the example of detailed preparations and methods used by the German and Croatian armies to deceive their opponents and achieve success in warfare. Finally, a comprehensive conclusion was reached based on the similarities and differences of the above operations.
