US Army’s New Doctrine for Multinational Operations

The US Army is facing a rapidly evolving world stage. Gone are the days of solely focusing on counterinsurgency operations; the landscape is now defined by near-peer adversaries and the growing complexity of modern warfare. Recognizing this shifting reality, the Army has just released a comprehensive update to its flagship doctrine for multinational operations, Field Manual 3–16, “The Army in Multinational Operations.”

This isn’t simply a facelift; it represents a fundamental rethinking of how the US Army prepares for and conducts joint operations with allies and partners. This new iteration, released in July 2024, signals a clear shift towards large-scale combat operations, emphasizing interoperability and mutual trust as crucial for success in the face of powerful adversaries.

Building Bridges: The Importance of Interoperability and Mutual Confidence

At the heart of the revamped FM 3–16 lies a fundamental understanding that fighting alongside partner forces requires more than just shared objectives. True success hinges on achieving interoperability. This concept, thoroughly discussed throughout the manual, goes beyond basic language skills and logistical compatibility; it embraces the shared understanding of tactics, doctrine, and even cultural nuances.

The manual explicitly states that trust, not just within individual units, but between nations, is a crucial cornerstone of this interoperability. The emphasis is on mutual confidence — the assurance that partners will act in a cohesive and reliable manner even in the face of extreme stress and pressure. This isn’t built overnight; it requires consistent exercises, clear communication channels, and a long-term investment in building solid relationships.

The updated manual addresses this need for trust head-on. It delves into the development of shared operational frameworks and emphasizes the critical role of robust command and control systems. Gone are the days of loosely defined collaboration; FM 3–16 stresses a structured, well-defined approach to ensure clarity and coordinated action between forces.

Command and Control: Balancing Unity and Authority

Command and control in multinational operations isn’t simply a logistical concern. It’s a delicate balance of unity of effort and operational control. The manual outlines how to ensure all partners work towards the same objective while respecting the autonomy and unique capabilities of individual forces.

The manual addresses these complexities through various tools and techniques. One example is the introduction of the Mission Partner Environment (MPE) and Prov — dedicated structures designed to facilitate smooth communication, shared planning, and effective resource allocation. This is critical as it allows for coordinated decisions, streamlining operational execution and maximizing efficiency in diverse military contexts.

Sustainment: Beyond Logistical Support

The new FM 3–16 recognizes that sustainment goes far beyond simply supplying troops with food, fuel, and munitions. It emphasizes the need for resource management in a joint environment. This involves harmonizing logistics systems, allocating resources fairly, and ensuring all partners contribute effectively to the common goal.

The document emphasizes the importance of understanding the nuances of different partner countries’ logistical processes and procedures. This understanding paves the way for effective cross-border logistics, allowing for seamless resupply even when facing challenging terrain, weather conditions, or the constant pressure of a demanding operational environment.

Adapting to the New Landscape: The Evolution of Doctrine

The updated FM 3–16 isn’t just about incorporating new technologies or streamlining processes; it is about recognizing that the modern battlefield requires adaptability. The manual acknowledges the importance of integrating special operations, cyber warfare, and space operations in a multinational context. These elements have become increasingly relevant in modern conflict, offering unique advantages when wielded effectively and strategically.

To further highlight this adaptability, the manual dives into the changing information landscape and the increasing significance of information warfare. Gone is the old chapter on “inform and influence,” replaced by a more robust approach aligned with contemporary principles outlined in Army Doctrine Publication (ADP) 3–13, “Information.”

Looking Forward: The Promise of a Collaborative Future

This new version of FM 3–16 underscores the US Army’s commitment to evolving alongside the dynamic international security environment. It’s a clear signal that success in the future lies not in the might of a single nation, but in the power of shared understanding, cohesive planning, and coordinated action across diverse military forces.

This manual offers not just a roadmap for operational success, but a vision for a more collaborative and interconnected future — a future where diverse nations work in unison to meet common threats and uphold shared values.
