PALS is designed to bring together senior leaders of allied and partner Marine Corps, naval infantries, and militaries spanning the Indo-Asia-Pacific region. This year, 22 nations sent representatives to observe this training and participated in meaningful dialogues on key aspects of maritime and amphibious operations, capability development and interoperability.
