Chilean-led Special Operations Forces (SOF) exercise Southern Star 2025 is set to start in Chile, May 24-June 11. In its 18th edition, the exercise features a strong multinational presence with 10 participating nations and 15 observer countries. Originally a binational training event between special forces of Chile and the United States, Southern Star has evolved to become one of Latin America’s most significant SOF exercises.
