In the newly proposed post-conflict scenario in Colombia, the Armed Forces are engaged in a process of transformation, and one of the objectives of this process is to increase and improve joint operations, that is, those planned and executed by two or more military forces. The first step towards this objective occurred in 2003 with the creation of the Omega Joint Task Force, based on the experience of the United States Armed Forces. This article analyzes the US Operation Iraqi Freedom —especially the strategic level and the unity of command— and compares it with the results achieved so far by Colombia in the field of joint operations, where the generation of synergies and operational flexibility have increased the accuracy, strength, and efficiency of the Military Forces.
