This current historic research aims to describe how the strategies of war used by the Colombian army in the history of Colombia, from 1930 to 2006, have evolved. To do so, first the strategies of war will be defined conceptually, and then, those used by the Colombian army, will be introduced. Finally, it will be attempted to make evident their evolution in this armed body, managing to leave further routes of analysis which can cross several variables, in order to better understand the reality of a long armed conflict as it is the Colombian case
