US Deploys M142 HIMARS Rocket Launchers in Southern Command Area for First Time.

The United States Army deployed the M142 High Mobility Artillery Rocket System (HIMARS) to the U.S. Southern Command’s area of operations for the first time as part of the Southern Fenix 24 (SF24) military exercise. This multinational training, which took place in Chile from August 27 to September 6, 2024, involved over 600 troops from Chile, Argentina, and the United States, aiming to strengthen hemispheric cooperation and enhance interoperability for future multi-domain operations.

The Oklahoma-based "Steel Warriors" of the 1st Battalion, 14th Field Artillery Regiment (1-14 FAR) were deployed to Chile’s Atacama Desert in the Tacapacá region, bringing the formidable M142 HIMARS. This advanced rocket system, designed by Lockheed Martin, has proven its effectiveness in recent conflicts, including the 2022 Russian invasion of Ukraine. With a 70-84 km range when firing Guided Multiple Launch Rocket System (GMLRS) rockets and up to 300 km with Army Tactical Missile System (ATACMS), the HIMARS offers long-range precision strike capabilities. Its mobility, accuracy, and rapid redeployment abilities make it a valuable asset in modern combat operations.

The 1st Battalion, 14th Field Artillery Regiment (1-14 FAR) is a U.S. Army unit specializing in field artillery, providing long-range, precision fire support in combat operations. Known by their nickname, the "Steel Warriors," the 1-14 FAR is a part of the 75th Field Artillery Brigade, based at Fort Sill, Oklahoma. The battalion is equipped with advanced artillery systems, including the M142 High Mobility Artillery Rocket System (HIMARS), allowing for rapid deployment and highly accurate strikes on point and area targets.

During SF24, U.S. troops engaged in artillery training with the Chilean Army, deepening military ties and strengthening their ability to operate together in future joint missions. The 1-14 FAR U.S. soldiers were enthusiastic about showcasing the HIMARS' capabilities while building relationships with their Chilean counterparts. Lt. Col. Anthony Allen, battalion commander of the 1-14 FAR, emphasized the importance of this exercise, expressing optimism for continuing this collaboration. He noted that the operation is a key step in enhancing U.S.-Chilean military interoperability, vital for future multi-domain operations across the region.

The Southern Fenix 24 exercise not only highlights the tactical value of the HIMARS but also reinforces the strategic importance of cooperation between the U.S. and South American militaries. As hemispheric security challenges evolve, the ability to deploy and train with cutting-edge systems like HIMARS enhances readiness and strengthens regional alliances.

The presence of the U.S. Army in South America reflects a broader U.S. strategy to enhance regional security, support counter-narcotics operations, and strengthen military partnerships with allied nations. U.S. military involvement in the region is primarily coordinated through U.S. Southern Command (SOUTHCOM), which oversees operations and collaborations across Central and South America and the Caribbean. SOUTHCOM's mission includes fostering defense cooperation, promoting stability, and addressing regional threats like organized crime and natural disasters. The U.S. military often engages in joint training exercises, humanitarian aid efforts, and capacity-building initiatives with partner nations in the region to improve mutual readiness and foster stronger ties.

Regarding defense relations with Chile, the United States and Chile have a long-standing and robust military partnership. Chile is considered one of the U.S.'s most reliable defense partners in South America, with a history of collaboration that spans several decades. This relationship has been formalized through various defense agreements, including the Defense Cooperation Agreement, which facilitates joint training exercises, military education, and defense technology sharing. Chile is also a member of the State Partnership Program (SPP) through its connection with the Texas National Guard, further deepening military-to-military ties.

Both nations regularly participate in joint military exercises, such as Southern Fenix (SF) and Southern Star, to improve interoperability, enhance capabilities for multi-domain operations, and address shared security concerns. Chile's strategic location and its emphasis on modernizing its military make it a valuable defense partner for the U.S. in the South American region. This defense cooperation has also contributed to regional stability and has played a role in international peacekeeping operations where Chilean and U.S. forces have worked side by side.
