The live phase of “JFX/MDO-25”, the Armed Forces' operational structure training exercise, begins

In El Retín, Cádiz
November 24, 2025
  •  In this edition, the objective is to achieve the level of training required for joint and complex operations in the multi-domain, under the operational control of the Operations Command

Until next Friday, 28th November, the Retín Manoeuvre Field will host the “real-life” phase of the JFX25 exercise. This is a training exercise for the operational structure of the Armed Forces in the multi-domain field.

At this stage, multi-domain experimentation activities will be carried out with real-time video transmission, execution of a ground attack, and video and data transmission for damage assessment, while space operations forces will be trained.

Real forces on the ground will carry out offensive operations using special operations units, air assets and naval units.

All of them will use satellite means to link 5G bubbles, with the aim of facilitating the command and control of military actions. Likewise, Electronic Warfare (EW) units will attempt to disrupt and hinder their own actions, with the aim of testing the resilience and strength of communications systems and the capacity for coordination in military actions in a multi-domain environment.

This field training will enable the exchange of information for the partial application of joint combat functions —(fire, command and control, and intelligence, surveillance and reconnaissance)— through the use of overlapping 5G bubbles that cover the entire territory. The participation of several Spanish technology companies has been key to the execution of this experiment.

About Exercise ‘JFX’

This activity is carried out every three years, and its objective is to train and test the Operations Command's ability to exercise operational control of the various Component Commands: Land, Maritime and Air, Space, Cyberspace and Special Operations.

This training activity is defined as a level 3 exercise (strategic, operational, and tactical) and is divided into two phases focused on training the Armed Forces' operational structure in the planning and conduct of high-intensity multi-domain operations—land, sea, air, cyberspace, and space.

In this scenario, our troops must independently confront an adversary with highly demanding and advanced capabilities, paying particular attention to everything that happens in the cognitive sphere.

During the first phase, the Command Post exercise is carried out. This is the main stage, as the Headquarters of the various Component Commands, the Armed Forces Intelligence Centre (CIFAS) and the Command Post of the Chief of Defence are activated. Each of them operates from their respective bases and barracks, and their participation involves joint and multi-domain operational planning. In the second part of JFX/MDO 25, a real-life exercise is carried out.
