What's Happening?
The U.S. Marines are spearheading the 66th iteration of UNITAS, the world's longest-running multinational maritime exercise, which commenced on September 15, 2025, at Camp Lejeune, North Carolina. This year's exercise marks a significant shift as it is the first
time the amphibious phase is hosted at a major Marine installation in the U.S. rather than in South America. Over 2,000 Marines are collaborating with servicemembers from 25 partner nations to enhance their capabilities in amphibious warfare and regional security. The exercise aims to improve multinational interoperability and build upon the amphibious and littoral combat power of all participants. Key activities include close air support training and urban warfare exercises, with a focus on integrating cutting-edge technology such as the Autonomous Low-Profile Vessel (ALPV) for expeditionary advanced base operations.
Why It's Important?
UNITAS 2025 is crucial for strengthening military alliances and enhancing the collective defense capabilities of the participating nations. By fostering multinational collaboration, the exercise helps deter potential threats and ensures rapid crisis response across Central America, South America, and the Caribbean. The integration of advanced technology, such as unmanned systems, demonstrates the U.S. Marine Corps' commitment to innovation and adaptability in modern warfare. This exercise not only reinforces the U.S. Southern Command's strategic objectives but also serves as a platform for testing new military strategies and technologies that could be applied in other global theaters.
What's Next?
As UNITAS 2025 progresses, participating nations will continue to refine their tactics and techniques, focusing on seamless communication and coordination in high-stakes scenarios. The lessons learned from this exercise are expected to influence future military operations and collaborations, particularly in the realm of unmanned systems and expeditionary logistics. The successful execution of UNITAS 2025 could lead to more frequent and larger-scale multinational exercises, further solidifying military partnerships and enhancing regional security.
Beyond the Headlines
The exercise highlights the importance of multinational military cooperation in an era of great-power competition. By operating in realistic, crisis-like scenarios, UNITAS 2025 not only deters aggression but also strengthens the collective response capabilities of the participating nations. The focus on integrating advanced technology and unmanned systems reflects a broader trend in military strategy, emphasizing the need for agility and resilience in modern warfare. This approach could redefine maritime sustainment and influence military operations beyond the U.S. Southern Command's area of responsibility.
