According to the news released on the official website of the British Army, the "Hellhound-22" military exercise led by the British Army will be held in Senegla, Germany. This exercise is the largest exercise organized by the British Army in the European continent in the past 10 years. At the same time, the UK will rejoin the EU's "Military Mobility Plan" to enhance its ability to conduct cross-border military movements within EU member states. According to the report, the "Hell Dog - 22" exercise will be mainly organized and implemented by the 3rd British Army Division. The division belongs to a synthetic force, and has a variety of combat support forces, including reconnaissance, armored cavalry, mechanized infantry, aviation, artillery, engineering and logistics support. According to Owen Luke, Chief of Staff of the Third Division of the British Army, the British Army is expected to send about 3300 officers and soldiers, more than 800 vehicles and 6 brigade command posts to participate in the exercise. The 3rd Brigade Combat Team under the First Cavalry Division of the US Army, French, German and other countries will also appear in the exercise. The exercise will further enhance the interoperability of the British and American militaries. It is reported that the "Hell Dog" series of exercises had been held in the Salisbury Plain Training Area in the UK. This year, the exercise site was adjusted to the central region of Europe to test the ability of the British Army to mobilize personnel and equipment on a large scale and carry out overseas operations. Luke said that the exercise will be carried out by Etothenegra's "regional land hub", focusing on the British army's ability to rapidly deploy to the European continent. In 2021, the British army will establish a "regional land hub" in the NATO base in Senegla, and store a large number of combat support vehicles and equipment, which can support the British army to respond quickly and also provide a training venue for the British army. In addition to the vehicles and equipment originally stored in Germany, the British Army's participating forces and other weapons and equipment will be transported to the exercise site by the British Air Force, the Navy and the Allied forces by sea, land and air. The participants were first transported by the A400 transport plane of the British Air Force to the "Air Training and Exercise Center" in Zeller, Germany, and then transported by the CH53 transport helicopter of the German Defense Forces to Senegra. The equipment will be delivered to the target area by sea. This will give the British Air Force and the German Defense Forces the opportunity to train together. The British Army Officer Network said that the exercise was directly commanded by the headquarters of the 3rd Division, and the NATO Joint Rapid Response Force led by the British army would be responsible for the command and control of the exercise at the NATO level, highlighting the importance of NATO alliance relations and the high level of the exercise. Shortly after the announcement of the exercise on the British Army official website, Dutch Defense Minister Olongren told the British Guardian that Britain would return to the EU's "military mobility plan". This plan, initiated by the Netherlands, aims to simplify the procedures for cross-border military mobilization within the EU, eliminate red tape, and enable participating countries' armies to send personnel and equipment to the front more quickly. The UK was a member of the scheme and withdrew immediately after "Brexit". The "military mobility plan" was originally an internal mechanism of the European Union, but in view of the accession of the United States, Canada and Norway last year, there was no obstacle for the United Kingdom to "join" again. It is expected that the UK will officially return to the program in the middle of this month. Analysts pointed out that the "Hell Dog - 22" exercise was transferred
