Throughout history, air power has played a fundamental and decisive role in developing war conflicts. Its power of reach and impact on the adversary have marked drastic changes in battle. Likewise, the power to affect people and facilities outside the conflict is highly remarkable. For this reason, countries with experience in large-scale conflict created the Joint Terminal Attack Controller (JTAC), responsible for ensuring fluid communication between air and land power, identifying military targets, and avoiding collateral damage. Given the Colombian internal conflict and the urgent need to develop military defense capabilities for the nation, the Colombian Air Force must expedite the training and implementation of the JTAC capability. For the Colombian doctrine, it will be named Terminal Attack Air Controller (CAAT). However, the JTAC training process is complex and involves time, resources, expert personnel, and authorizations in the field. This article proposes a detailed look at how JTACs are currently prepared and trained in countries such as the United States and Spain to learn and identify good practices, as well as a small sample of the process that Colombia has taken in the development thereof and the aspects to be improved to be able to successfully carry out the development and application of this new capability for the defense of the nation.
