U.S. Marine Corps Force Design 2030: Reshaping for Expeditionary Advanced Base Operations
The U.S. Marine Corps is undergoing its most radical transformation in decades. Since March 23, 2020, when then-Commandant General David H. Berger unveiled Force Design 2030, the Corps has been systematically dismantling legacy capabilities and rebuilding itself from the ground up — not because tradition demanded it, but because the future of warfare left no other choice.
This isn’t a routine modernization. Force Design 2030 represents a fundamental reimagining of what the Marine Corps is, what it does, and who it fights. The initiative eliminates entire categories of equipment, cuts roughly 12,000 personnel, and creates new kinds of units designed to fight and survive in environments where the enemy holds every geographic and technological advantage. At its core, Force Design 2030 is a calculated bet that the next major conflict won’t look like Iraq or Afghanistan — it will look like the western Pacific, and the Marines intend to be ready.
Understanding this transformation matters well beyond military circles. The strategic logic behind it, the capabilities being gained and lost, and the ongoing debates about whether it’s the right path forward touch on some of the most consequential questions in modern defense policy. Here’s a comprehensive breakdown of everything you need to know.

The Strategic Imperative: Why Force Design 2030 Was Non-Negotiable
A World Transformed by Peer Competition
For two decades following 9/11, the Marine Corps — like much of the U.S. military — oriented itself around counterinsurgency, stability operations, and irregular warfare. That era shaped procurement decisions, training pipelines, and organizational structures in ways that left the Corps increasingly misaligned with the threats now dominating Pentagon planning documents.
The 2018 National Defense Strategy changed everything. It explicitly shifted U.S. defense priorities away from violent extremist organizations and toward “long-term strategic competition” with China and Russia. For the Marine Corps, this meant confronting an uncomfortable truth: a force optimized for kicking down doors in Fallujah was not the same force needed to contest Chinese maritime expansion in the South China Sea or the Taiwan Strait.
China’s military modernization — particularly the People’s Liberation Army’s development of sophisticated anti-access/area denial (A2/AD) capabilities — created a threat environment that traditional amphibious doctrine simply wasn’t designed to handle. Long-range precision missiles, advanced air defense networks, and increasingly capable naval forces have made the idea of massing large amphibious assault fleets within range of a peer competitor’s coastline extraordinarily dangerous. In a high-end conflict against China, the old playbook could get Marines killed before they ever reached the beach.
The A2/AD Problem and Why It Drives Everything
China’s A2/AD architecture is designed to deny the U.S. military freedom of movement in the western Pacific. Systems like the DF-21D anti-ship ballistic missile — capable of targeting aircraft carriers at ranges exceeding 1,000 miles — fundamentally alter how naval forces can operate in the region.
This is the threat environment that gave birth to Force Design 2030. General Berger’s 38th Commandant’s Planning Guidance, released in 2019, argued that the Marine Corps needed to become a “naval expeditionary force-in-readiness” capable of operating inside an adversary’s A2/AD envelope, not just around its edges. Rather than massing combat power at predictable points of embarkation, the new Marine Corps would disperse, hide, maneuver, and strike from positions the enemy couldn’t easily target or destroy.
That vision produced two foundational operational concepts that underpin everything Force Design 2030 is trying to accomplish.

Core Operational Concepts: EABO and LOCE Explained
Expeditionary Advanced Base Operations (EABO)
Expeditionary Advanced Base Operations is the conceptual engine driving Force Design 2030. At its simplest, EABO describes the employment of small, dispersed Marine units operating from a series of temporary, low-signature positions — called expeditionary advanced bases — within or near contested maritime environments.
Think of it this way: instead of one large amphibious task force that presents a single, identifiable, and targetable threat, EABO envisions dozens of small Marine teams scattered across island chains, operating from positions that are difficult to find and even harder to destroy. Each node might host a long-range missile battery, a reconnaissance team, a logistics cache, or an air defense element. Individually, none of these positions is decisive. Collectively, they create a web of lethal coverage that can deny an adversary the ability to move naval forces through a contested maritime space.
EABO units are designed around four key characteristics: low signature (difficult to detect), mobile (able to reposition before being targeted), resilient (distributed enough that destroying any one node doesn’t collapse the whole), and lethal (capable of delivering precision fires at extended ranges). In the context of the Indo-Pacific, this translates to Marine forces operating across island chains like the Ryukyus or the Philippines’ northern islands — essentially turning geography into a weapon against Chinese naval power.
The operational contribution is real and measurable: EABO forces conducting sea denial can force enemy naval vessels to either avoid entire maritime corridors or expose themselves to attritional fires. That capability directly supports the Navy’s Distributed Maritime Operations concept, which similarly seeks to complicate adversary targeting by spreading naval combat power across vast ocean areas.
Littoral Operations in a Contested Environment (LOCE)
Littoral Operations in a Contested Environment provides the broader doctrinal framework within which EABO sits. LOCE explicitly acknowledges that future Marine operations will occur within an adversary’s weapons engagement zones — meaning Marines will be fighting within range of enemy sensors and fires from the moment they enter the operational area.
This is a significant departure from Cold War and post-9/11 thinking, where the assumption was that U.S. forces would establish air and sea superiority before ground forces moved forward. LOCE rejects that assumption. It demands a force capable of surviving, maneuvering, and achieving effects while under persistent threat of detection and attack — a much harder problem that requires fundamentally different organizations, equipment, and tactics.
Together, EABO and LOCE define the operating environment the new Marine Corps is being built to master.

Key Pillars of Transformation: What’s Actually Changing
Marine Littoral Regiments: The Centerpiece Formation
The Marine Littoral Regiment (MLR) is Force Design 2030’s most visible organizational innovation. Conceived specifically to execute EABO, the MLR is a self-sufficient, combined-arms formation designed to operate in island and coastal environments with minimal external support.
Each MLR consists of four primary elements: a Littoral Combat Team (infantry-centric maneuver force), a Littoral Anti-Air Battalion (air defense), a Littoral Logistics Battalion (extended sustainment), and a Combat Logistics Battalion. This structure gives the regiment the ability to sustain itself in austere, remote environments while delivering precision fires, defending its positions from aerial threats, and conducting reconnaissance and counter-reconnaissance.
The MLR’s most significant capability is long-range precision fires. Equipped with systems like the Naval Strike Missile Expeditionary Launch System (NMESIS) — a truck-mounted anti-ship missile launcher — an MLR can threaten enemy surface vessels at ranges exceeding 100 nautical miles. That’s a ground unit, operating from a small island, capable of sinking warships. The strategic implications are significant.
The 3rd Marine Littoral Regiment was established in Hawaii in 2021, making it the first fully operational MLR and the template for subsequent formations. Its positioning in the Pacific underscores exactly which operational theater Force Design 2030 is built around.
What the Marine Corps Is Giving Up
The divestments associated with Force Design 2030 are sweeping and, for many Marines, deeply painful. The logic is straightforward: capabilities optimized for large-scale land warfare don’t contribute meaningfully to EABO, and maintaining them costs money, personnel, and institutional attention that the new force design needs elsewhere.
Ground Forces:
– All 7 tank battalions eliminated — the Marine Corps no longer operates main battle tanks
– Cannon artillery batteries reduced from 21 to just 5
– Infantry battalions reduced from 24 to 21
– All bridge companies eliminated
Aviation:
– F/A-18 Hornet squadrons reduced from 10 to 8
– Heavy helicopter (CH-53) squadrons reduced from 4 to 2
– MV-22 Osprey squadrons reduced from 17 to 14
The elimination of tanks drew the most criticism. For generations, Marine tankers argued that armor provides an irreplaceable capability on the modern battlefield — one that no missile system fully replicates. The Corps’ position is that tanks are too heavy, too logistically demanding, and too difficult to deploy across the island-hopping terrain where future conflicts will be decided. That debate continues.
What the Marine Corps Is Gaining
The investments accompanying these divestments are equally significant. Force Design 2030 channels freed resources into capabilities specifically suited for contested littoral environments.
Long-Range Precision Fires: NMESIS represents perhaps the most visible capability gain. The ability to deploy truck-mounted anti-ship missiles from austere island positions is directly enabled by Force Design 2030’s investment priorities.
Unmanned Systems: The new force design makes substantial investments in unmanned aerial vehicles (UAVs), unmanned surface vessels (USVs), and unmanned ground vehicles (UGVs). These systems extend the reach of small Marine units, provide persistent reconnaissance without risking personnel, and can complicate enemy targeting by adding more low-signature nodes to an already distributed force.
Reconnaissance and Air Defense: Enhanced counter-reconnaissance and air defense capabilities are critical to EABO’s survivability logic. If enemy forces can locate and strike an expeditionary advanced base faster than it can reposition, the entire concept fails. Investments in sensors, electronic warfare, and air defense systems are what make dispersed operations viable.
Cyber and Information Warfare: The new force design significantly expands Marine Corps capacity for cyber operations, electronic warfare, and information operations — capabilities that are essential in a contested electromagnetic environment.
Personnel and Organizational Changes
The overall force reduction of approximately 12,000 personnel by 2030 isn’t simply a cost-cutting measure. It reflects a deliberate choice to trade mass for capability, accepting a smaller force in exchange for one that is more precisely tailored to the anticipated threat.
Associated initiatives — Training and Education 2030, Talent Management 2030, and Installation and Logistics 2030 — are designed to reshape how Marines are recruited, trained, retained, and supported. New military occupational specialties (MOS) have been created to fill gaps in areas like unmanned systems operation, fires coordination, and littoral reconnaissance. These aren’t cosmetic changes; they represent a fundamental rethinking of what skills the Marine Corps values and rewards.

Broader Implications: The Joint Force, Allies, and the Navy Connection
Integration with Distributed Maritime Operations
Force Design 2030 cannot be understood in isolation. It is explicitly designed to complement the U.S. Navy’s Distributed Maritime Operations (DMO) concept, which similarly seeks to spread naval combat power across large ocean areas to complicate adversary targeting.
The relationship is symbiotic. MLRs operating from island positions can conduct sea denial, forcing enemy naval forces to either avoid maritime corridors or expose themselves to fires — which directly supports Navy surface action groups operating in the same contested space. Marines provide the land-based fires and reconnaissance that extend the Navy’s reach; the Navy provides the mobility and fires support that enable Marines to operate and survive.
This integration is arguably the most strategically significant aspect of Force Design 2030. It redefines the Marine Corps as a naval force in the truest sense — not just an amphibious force that uses ships for transportation, but a maritime warfighting entity whose ground combat capabilities directly enable naval operations.
The Navy Medium Landing Ship: A Critical Enabler
The Navy Medium Landing Ship (LSM) — formerly referred to as the Light Amphibious Warship (LAW) — is essential to Force Design 2030’s mobility concept. MLRs operating across island chains need platforms capable of moving small teams and their equipment between austere positions without requiring major port facilities.
Large amphibious assault ships are too valuable and too visible to use for this kind of distributed, persistent positioning. The LSM is designed to be smaller, more numerous, and capable of operating in the shallower coastal waters where MLRs will maneuver. It’s the connective tissue that allows the dispersed nodes of an EABO network to be supplied, reinforced, and repositioned. The program’s development trajectory directly tracks the Force Design 2030 timeline.
Implications for Allies and Partners
Force Design 2030 has significant implications for allied and partner nations, particularly in the Indo-Pacific. Japan, Australia, the Philippines, and other regional partners are increasingly integrated into the operational concepts that MLRs are designed to execute.
The prospect of Marine forces operating from allied territory — Japanese islands in the Ryukyu chain, for instance — raises important questions about host nation support, combined operations, and diplomatic sensitivities. At the same time, the distributed nature of EABO creates opportunities for allied forces to plug into a broader network of maritime denial capabilities. Several partner nations have expressed interest in developing their own versions of the littoral strike concept, which could significantly multiply the strategic effect of Force Design 2030 across the region.

Challenges, Criticisms, and Ongoing Debate
The Case Against Eliminating Tanks
The most persistent criticism of Force Design 2030 targets the elimination of Marine tank battalions. Critics — including a number of retired senior officers and defense analysts — argue that tanks provide capabilities no other platform replicates: direct fire support in complex terrain, armored protection in close combat, and psychological impact on enemy forces.
The CSIS analysis of Force Design 2030 noted that while the Indo-Pacific focus is sound, the elimination of heavy armor creates real capability gaps in other potential scenarios — particularly in Europe or the Middle East, where conflicts might demand the combined arms integration that tanks enable. The Marine Corps’ counterargument is that the force can access Army armor when needed, and that maintaining tanks within the Corps consumes resources better spent on capabilities the Army doesn’t provide. That’s a reasonable position, but it assumes a level of joint force integration that doesn’t always materialize under the stress of actual operations.
Readiness Risks During the Transition
Perhaps the most operationally urgent concern is what the Marine Corps Association has described as “the most dangerous period of Force Design 2030” — the transition itself. While legacy capabilities are being divested and new ones are still being fielded, the Corps is operating with a force that is neither what it was nor what it intends to become.
The units and systems that have been cut are gone. The units and systems meant to replace them — MLRs fully equipped with NMESIS, unmanned systems, enhanced air defense — are still being developed, procured, and fielded. During this gap, the Marine Corps’ ability to respond to crises that don’t fit the EABO template is genuinely reduced. This isn’t a hypothetical concern; it’s the acknowledged risk of any major transformation, and it’s particularly acute when the transformation is as sweeping as this one.
Funding, Budget Realities, and Congressional Scrutiny
Force Design 2030 has attracted sustained congressional attention, particularly regarding the pace of divestments versus the timeline for fielding new capabilities. The CRS Report R47614 documents ongoing concerns from lawmakers about whether the Marine Corps is managing the transition responsibly and whether funding levels are adequate to achieve the stated objectives.
The LSM/LAW program has faced schedule pressures and cost questions. Unmanned systems programs are navigating the usual procurement challenges. And the broader defense budget environment — with competing priorities across all services — creates real pressure on the resources needed to execute Force Design 2030 as designed. How the Corps manages these constraints over the remaining years of the plan will significantly shape what the 2030 force actually looks like.
Effectiveness Beyond the Indo-Pacific
A fundamental question lurks beneath the surface of Force Design 2030: what happens when the next crisis doesn’t look like a Taiwan Strait conflict? The Marine Corps has historically been the nation’s rapid response force for the full spectrum of contingencies — humanitarian disasters, non-combatant evacuations, counterterrorism operations, and conventional warfare across diverse geographies.
A force optimized for EABO in the Pacific may be less versatile across that full spectrum. The Corps’ leadership argues that capabilities are transferable and that the underlying competencies — small unit leadership, expeditionary logistics, combined arms integration — remain. Critics argue that the specific equipment and organizational design decisions made under Force Design 2030 create genuine gaps in other mission sets. This debate will likely continue well past 2030.

The Road Ahead: Progress, Updates, and Future Evolution
Annual Updates and Experimentation
Force Design 2030 is not a static document. The Marine Corps has published formal annual updates — in 2021, 2023, and 2025 — that incorporate lessons from experimentation, wargaming, and operational experience. The 2021 update, covered by USNI News, reflected a year of field experimentation with new formations and concepts, resulting in adjustments to both organizational designs and equipment requirements.
This iterative approach reflects intellectual honesty about the difficulty of transforming a large military institution and the inherent uncertainty of predicting future warfare. General Berger and his successors have consistently framed Force Design 2030 as a learning process rather than a fixed blueprint. The October 2025 update and the capstone operating concept “FIRST TO FIGHT” (May 2026) represent the latest articulations of where the Corps is and where it’s heading.
Milestones Achieved and Remaining
The 3rd Marine Littoral Regiment in Hawaii stands as Force Design 2030’s most concrete achievement — a purpose-built formation that didn’t exist five years ago, equipped with capabilities the Marine Corps never previously fielded. Exercises and experiments involving MLR units have demonstrated operational concepts that were purely theoretical when Force Design 2030 was announced.
The path forward involves completing the fielding of LSM platforms, reaching full operational capability with unmanned systems across the force, and refining the training and education frameworks that will produce Marines capable of executing EABO at scale. Whether all of these objectives are achieved by 2030 — and what the force looks like if they’re not — depends heavily on funding, technology development timelines, and strategic circumstances that remain in flux.
Beyond 2030: An Ongoing Adaptation
It’s worth emphasizing that “2030” in Force Design 2030 describes a target, not a terminus. Military force design is inherently iterative — what works in concept doesn’t always work in practice, adversaries adapt, technology evolves, and strategic environments shift in ways no planning document fully anticipates.
The Marine Corps of 2031 will almost certainly look different from the Marine Corps of 2030 as originally envisioned. What matters is whether the institutional processes, the operational concepts, and the strategic logic embedded in Force Design 2030 create a force that is genuinely more capable of meeting the threats the nation faces. That judgment will ultimately be made not by planners, but by events.

Conclusion: A Transformed Marine Corps for a New Era
Force Design 2030 represents the most consequential restructuring of the U.S. Marine Corps since the post-World War II era. Initiated under General David H. Berger on March 23, 2020, it has eliminated tank battalions, dramatically reduced cannon artillery and aviation assets, cut roughly 12,000 personnel, and created entirely new formations — Marine Littoral Regiments — designed to execute Expeditionary Advanced Base Operations in the contested maritime environments of the Indo-Pacific.
The strategic logic is sound: China’s A2/AD capabilities have fundamentally changed what it means to operate in the western Pacific, and a Marine Corps built for a different era needed to change or risk irrelevance in the conflicts that matter most. The investments in long-range precision fires, unmanned systems, and distributed maritime capabilities represent genuine capability gains that complement the Navy’s own transformation.
The challenges are equally real. The transition period carries operational risk. The elimination of heavy armor creates genuine capability gaps. Budget pressures and procurement timelines may not align with strategic timelines. And a force optimized for one regional scenario may struggle in others.
What is undeniable is that the Marine Corps is taking the future seriously — asking hard questions about relevance, making difficult tradeoffs, and accepting significant institutional pain in pursuit of strategic effectiveness. Whether Force Design 2030 succeeds in its ambitions will be one of the defining stories in American defense policy for years to come.

Frequently Asked Questions
What exactly is Force Design 2030?
Force Design 2030 is a comprehensive transformation initiative for the U.S. Marine Corps, announced on March 23, 2020, by then-Commandant General David H. Berger. It redesigns the Corps’ structure, equipment, and doctrine to focus on Expeditionary Advanced Base Operations in contested maritime environments, particularly the Indo-Pacific region. The plan involves divesting legacy capabilities like tanks and heavy artillery while investing in long-range precision fires, unmanned systems, and new formations like Marine Littoral Regiments.
Why did the Marine Corps eliminate its tank battalions?
The decision to eliminate all 7 Marine tank battalions was driven by the assessment that main battle tanks are too heavy, too logistically demanding, and too difficult to transport and sustain across the island-chain terrain where Force Design 2030 envisions future operations. The Corps argues that Army armor assets can provide this capability when needed for joint operations, freeing Marine resources for capabilities that only the Corps provides in its new littoral warfare role. Critics dispute this reasoning, arguing it creates real capability gaps in other potential scenarios.
What is Expeditionary Advanced Base Operations (EABO)?
EABO is an operational concept in which small, dispersed Marine units operate from a series of temporary, low-signature positions — called expeditionary advanced bases — in contested maritime environments. These forces are designed to be difficult to detect, rapidly repositionable, and capable of delivering precision fires against naval targets at extended ranges. The goal is to create a distributed network of lethal nodes that can deny an adversary freedom of movement through contested maritime corridors.
What is the 3rd Marine Littoral Regiment and where is it based?
The 3rd Marine Littoral Regiment (3rd MLR) is the first fully operational Marine Littoral Regiment, established in Hawaii in 2021. It serves as the template for Force Design 2030’s new formation concept, combining a Littoral Combat Team, Littoral Anti-Air Battalion, and Littoral Logistics Battalion into a self-sufficient, combined-arms regiment designed for island-chain operations in the Pacific. Its positioning in Hawaii reflects the Indo-Pacific focus of Force Design 2030.
What are the main criticisms of Force Design 2030?
The major criticisms include: the loss of heavy armor capability and its implications for non-Pacific scenarios; the readiness risk during the transition period when old capabilities have been cut but new ones aren’t fully fielded; budget and procurement timeline pressures; questions about interoperability with allies; and concerns that a force optimized for China contingencies may be less effective in other regions or mission types. Congressional scrutiny has focused particularly on the pace of divestments versus the delivery of replacement capabilities.
How does Force Design 2030 relate to the threat from China?
Force Design 2030 is fundamentally a response to China’s anti-access/area denial (A2/AD) capabilities, which have made traditional amphibious assault concepts dangerously vulnerable in the western Pacific. China’s long-range precision missiles, advanced air defense networks, and growing naval forces threaten large, massed amphibious task forces. Force Design 2030 counters this by creating dispersed, hard-to-target Marine units that can operate inside the A2/AD envelope, conducting sea denial and supporting Navy operations — directly complicating Chinese maritime strategy.
