Decisive operations are those which directly influence successful outcome of the main operation and represent main effort in realization of the same. In other words, these are operations which directly perform the mission assigned by superior commandment. This work gives a comparison of current doctrinal discusions on decisive operations with traditional view of military theoreticians like von Clausewitz and Jomini who have described the concept of decisive operations using terms “center of gravity” and “decisive points”. Usage of two examples which have no common points makes it easier for the reader to understand the link between these terms and the definition of decisive operations as we know it today. The first operation mentioned is one from World War II, where Japanese attacked Singapore in order to disable British Royal Navy to stand against Japanese occupation of nearby islands and their expansion toward Australia, while the second operation is one of the final operations from Croatian Homeland War, it is operation “Summer 95”, which created terms for fulfillment of operation “Storm”.
