The EU has taken another step towards militarization in order to survive in an unstable global situation. Josep Borrell, High Representative for European Foreign and Security Policy, said that the European Union would conduct its first joint military exercise in Spain in 2023. According to a report on the website of Spanish newspaper El Pais on December 10, in the second half of next year, when Spain holds the rotating presidency of the European Union, the new military department of the European Union, the so-called rapid reaction force (which will be composed of 5000 soldiers), will conduct the first exercise on the ground. However, there is an important issue to be resolved: how much will the exercise cost and how to fund it. The exercise aims to test the rapid reaction force planned to be deployed by 2025 for the first time. At that time, the command of this force will be transferred from the national unit to the Military Planning and Implementation Capability Mechanism (MPCC). The 2023 exercise in Spain will not mobilize all 5000 soldiers of the future force, but only a part of them. However, it is crucial to verify the command and control capability of MPCC. First of all, after taking substantive steps under the threat of the Kremlin and prompted by the Russian Ukrainian war, the Alliance followed its schedule for conducting joint military exercises. When introducing the annual expenditure report on the 9th, Borrell said, "Spain has committed to co host the first exercise of the European army". It is reported that through this rapid reaction force (which has been outlined in the EU strategic compass in 2021), Brussels is trying to eliminate the original concept of "European combat group". The concept has 1500 soldiers in theory, but has never been activated due to lack of political will. The new force is moving towards an operational intervention force with 5000 soldiers and financial resources to mobilize and train them. According to alliance sources, at present, the tasks planned to be carried out by this future rapid reaction force are based on two operational scenarios: the first stability maintenance operation and the subsequent rescue and evacuation operation. MPCC has been leading non war missions so far, focusing on training the army of a third country (Mali, the Central African Republic, Somalia or Ukraine). It will take over the command of the Rapid Response Force in 2025, but is preparing to expand its personnel. It remains to be determined where the joint exercise will be held in Spain and how many soldiers will participate. It is reported that in the next few months, the 27 countries will discuss their participation in the exercise and their funding sources. Part of the funds are borne by the host Spain; Other participating countries will pay part of the funds. According to EU sources, it remains to be determined whether the EU will provide financing for Spain as claimed. The progress of EU military cooperation is unprecedented. This progress was driven by the war and mixed threats provoked by the Kremlin. Since the outbreak of the conflict between Russia and Ukraine nearly 10 months ago, the European Union has launched historic defensive measures, and for the first time funded the purchase of lethal weapons to help Ukraine, a country in war. The EU has also proposed a 5 billion euro European fund to jointly purchase weapons for its member states and launched a training mission for Ukraine. Except for all these steps
