Executive Summary
Vision and Strategic Imperative
1. Purpose and Strategic Context
The Ground Combat Element (GCE) 2040 FY26 document provides the foundational framework for the U.S. Marine Corps to develop, prioritize, and balance investments shaping its GCE through 2040. It serves as a critical benchmark for ensuring the GCE remains a lethal and adaptable force. The concept acknowledges profound future uncertainty but understands that the core of the future force remains fundamentally human-centric, grounded in the willpower, discipline, and adaptability of the individual Marine. While focused on technological modernization, the framework asserts that to meet the challenges of a complex battlefield and the prospect of a peer adversary, the GCE must be designed for maximum mission flexibility and decisive combat power, all of which originates from the quality, training, and ethos of its warfighters.
2. The Evolving Character of War
The future battlefield is characterized by trends that challenge traditional ground combat, including ubiquitous sensors, artificial intelligence and machine learning (AI/ML), expendable drones, a contested electromagnetic spectrum, and long-range precision weapons that increase both transparency and lethality. This environment reduces the time for maneuver and places forces at ever-increasing risk. While technology offers unprecedented advantages, it also introduces critical vulnerabilities. The solution is not merely technological superiority but the development of a human-centered warfighting approach, where well-trained Marines are the center of gravity. This emphasis on the human element ensures the GCE can thrive in a high-tech environment but also remain resilient and effective when those technological advantages are degraded or denied by an adversary or the myriad of the inherent frictions of warfare.
3. The Core Military Problem
The central military problem addressed by this concept is the need to develop GCE formations capable of dominating peer-level ground combat through 2040. These formations must be able to thrive in an environment defined by advanced technology while also being resilient enough to operate effectively when those technological advantages are degraded or denied by an adversary. The GCE must combine the specialized functions of the Marine Littoral Regiment (MLR) with the enduring requirement to field combat formations that can seize, hold, and defend key maritime terrain across the full spectrum of conflict.
The Five Pillars of Modernization
I. Human-Centered Warfighting
Emphasizes that Marines are the center of gravity. This pillar focuses on the training, education, and ethos required to succeed on a complex, high-tech battlefield.
II. Lethality
Aims to increase the GCE’s ability to deliver kinetic and non-kinetic effects in all domains by enhancing organic fire support, integrating Joint fires, and expanding sensing capabilities.
III. Endurance
Focuses on protecting the force through all-domain defense, resilient logistics, tactical deception, and signature management to ensure the GCE can sustain combat operations against a peer adversary.
IV. Decision Advantage
Seeks to achieve dominance through Human-Machine Teaming, employing AI and autonomous systems to accelerate the decision-making cycle and displace Marines from the most dangerous tasks.
V. Modularity
Focuses on developing scalable and adaptable force organizations, centered on the Marine Air-Ground Task Force (MAGTF), that can be tailored to specific missions and threats.
The Strategic Framework
1. The Central Idea: A Human-Centric, Technology-Enabled Force
The future GCE is envisioned as a modular, task-organized, multi-domain force that combines dispersed operations, lethality, information dominance, and resilient command and control to seize and defend contested littoral terrain. While enabled by advanced technology, this force is fundamentally human-centric, grounded in the willpower, discipline, and adaptability of the individual Marine. Technology enhances human judgment but never replaces it. The endeavor is to achieve decision and lethality dominance by integrating AI-augmented decision-making with Human Machine Teaming, allowing the GCE to consistently out-sense, out-think, and out-maneuver any adversary.
2. Supporting Ideas: The Five Pillars of Modernization
The central idea is supported by five interconnected pillars that guide the GCE’s transformation:
-
Human-Centered Warfighting: Emphasizes that Marines are the center of gravity. This pillar focuses on the training, education, and ethos required to succeed on a complex, high-tech battlefield.
-

-
Modularity: Focuses on developing scalable and adaptable force organizations, centered on the Marine Air-Ground Task Force (MAGTF), that can be tailored to specific missions and threats.
3. High-Priority Capability Requirements
To realize this vision, the framework prioritizes the development of several Concept Required Capabilities (CRCs). The highest-priority areas for investment and development are:
-
CRC 1: Force Structure: Manning, training, and equipping the force to operate in a high-tech environment while maintaining excellence in fundamental warfighting skills.
-
CRC 2: Multi-Domain Lethality and Targeting: Employing kinetic and non-kinetic fires, enabled by AI and a network of distributed sensors, to engage targets with speed and precision.
-
CRC 3: Tactical and Littoral Mobility: Ensuring GCE formations can maneuver across complex and contested terrain, including littoral environments, with agile and resilient platforms.
Other critical enablers include resilient Combined Joint All-Domain Command and Control (CJADC2) Integration (CRC 4), sustainable Logistics in Contested Environments (CRC 5), and layered Ground-Based Air Defense (GBAD) (CRC 6).
Implementation and Future Outlook
1. A Phased Approach to Modernization
The transformation of the GCE will occur across three overlapping periods:
-
Near-Term (2026-2030): This period focuses on refining and accelerating on going Force Design modernization efforts, addressing the immediate threat of drones, and setting conditions for future investments.
-
Mid-Term (2031-2035): Investments in AI and autonomous systems will mature, enhancing headquarters functions, streamlining logistics, and improving operational tempo. Drone/unmanned formations and layered counter-UAS capabilities become critical.
-
Long-Range (2036-2040): The GCE is transformed by AI-enabled command and control, widespread Human-Machine Teaming, and resilient, dispersed formations. It operates with increased combat power and survivability, providing the Joint Force with a decisive advantage on key littoral terrain.
2. Material Solution Priorities
Achieving the 2040 vision requires targeted investment in materiel solutions across the warfighting functions:
-
Fires and Maneuver: Long-range surface-to-surface fires, all-weather direct and indirect fires, advanced mobility platforms (Amphibious Combat Vehicle, Advanced Reconnaissance Vehicle), and layered GBAD down to the squad level.
-
Command, Control, Intelligence, and Information: Resilient and scalable command posts, multi-domain sensing networks, counter-reconnaissance capabilities, and integrated data systems to enable CJADC2.

3. Conclusion
The GCE 2040 framework outlines a comprehensive vision for effectively integrating with the Joint Force and winning on the future battlefield. It balances the imperative for technological innovation with the enduring nature of ground combat. Key risks remain, including overcoming legacy fielding patterns and ensuring the survivability of mobility platforms and C2 networks. However, by adhering to its design principles, the Marine Corps will forge a GCE that is more lethal, resilient, and adaptable.
The GCE of 2040 will be a human-centric, technologically-enabled force that leverages AI, robotics, and multi-domain fires to achieve decision dominance, deter adversaries, and decisively prevail in conflict.
“You may fly over a land forever, you may bomb it, atomize it, pulverize it clean of life. But if you desire to defend it, if you desire to protect it, if you desire to keep it for civilization, you must do this on the ground, the way the Roman legions did…in the mud” – T.R. Fehrenbach
