Smith, a key figure in WWII amphibious operations. • Evolution of Name: Previously known as U.S. Pacific Command (USPACOM), the command was renamed to USINDOPACOM in 2018 to emphasize the growing importance of the Indian Ocean region. • World War II Roots: The command traces its lineage to World War II, when Admiral Chester W. Nimitz led the Pacific Ocean Areas command during the war against Japan. • Key Role in Korean and Vietnam Wars: USINDOPACOM was the primary strategic command for U.S. forces during the Korean War and the Vietnam War. • Multi-Service Command: USINDOPACOM includes all branches of the U.S. military—Army, Navy, Marine Corps, Air Force, Space Force, and Coast Guard—with a standing force of roughly 375,000 military and civilian personnel. • Disaster Relief Operations: The command frequently leads large-scale humanitarian and disaster relief operations, such as responses to the 2004 Indian Ocean tsunami and the 2011 Japan earthquake/tsunami. • Key Alliances and Partnerships: USINDOPACOM works closely with treaty allies such as Japan, South Korea, Australia, Thailand, and the Philippines, and maintains strong security relationships with India, Singapore, and many Pacific Island nations. • Freedom of Navigation Operations: USINDOPACOM regularly conducts freedom of navigation operations in the South China Sea and elsewhere, demonstrating U.S. commitment to international law and open sea lanes.
