Estado Mayor Conjunto

The Estado Mayor Conjunto, also known as the Joint Chiefs of Staff, is the senior military advisory body of Chile’s Ministry of Defense. It is responsible for providing strategic defense advice to the President of Chile and the Minister of Defense. The organization coordinates policy and planning across the Chilean Army, Navy, and Air Force to ensure a unified national defense posture. Its core functions include the development of joint doctrine, the oversight of interoperability initiatives, and the formulation of long‑term defense strategy. The Estado Mayor Conjunto also supervises joint exercises and evaluates the readiness of the armed forces for combined operations. In addition, it contributes to the national security council by offering military assessments that inform broader government policy on defense and security. The body participates in the preparation of the defense budget, ensuring that resource allocations reflect joint priorities and capability gaps. By serving as the principal link between political leadership and the military establishment, it helps translate national security objectives into actionable military guidance. Its work is continuous, with regular meetings and standing committees that address emerging threats and operational requirements.

As a governmental entity, the Estado Mayor Conjunto is organizationally situated within the Chilean Ministry of Defense and reports directly to the Minister of Defense and, ultimately, to the President of the Republic. Its structure comprises the chiefs of the three service branches together with a supporting staff that handles planning, intelligence, logistics, and communications functions. The body’s distinguishing attribute is its exclusive focus on joint, inter‑service coordination rather than the command of individual operational units. This specialization enables it to address complex defense challenges that require synchronized action across land, maritime, and air domains. The Estado Mayor Conjunto does not possess direct tactical authority over troops; instead, it provides guidance that is implemented by the respective service chiefs within their own chains of command. A notable event in its recent history was the May 2022 cyberattack attributed to the Guacamaya hacker group, which exposed approximately 350 GB of sensitive defense documents and underscored systemic shortcomings in data protection practices. The incident prompted high‑level resignations and renewed scrutiny of the organization’s cybersecurity posture, while also highlighting broader concerns about accountability and modernization within Chile’s defense establishment. Despite these challenges, the Estado Mayor Conjunto continues to fulfill its mandate of ensuring coherent defense planning and fostering cooperation among the armed forces. Its ongoing role is considered essential for maintaining Chile’s capacity to respond to both conventional and non‑traditional security threats.
