Marine Corps Transformation: Preparing for Pacific Warfare

The Marine Corps' Radical Transformation

The United States Marine Corps is undergoing a dramatic transformation to prepare for potential conflict in the Pacific region. This shift represents one of the most significant changes in Marine Corps history, as the force adapts to meet emerging threats and strategic challenges.

Historical Context

The Marine Corps has a storied history dating back to its founding in 1775. Traditionally, the Marines have served as an expeditionary force, specializing in amphibious operations and acting as a "force in readiness" for the United States. Their role in World War II's Pacific island-hopping campaign cemented their reputation as an elite fighting force.

However, recent decades saw the Marines' focus shift during conflicts like Vietnam and the Global War on Terror. Now, with growing tensions in the Pacific and concerns over China's expanding influence, the Marine Corps is refocusing on its naval roots and preparing for a potential conflict in maritime Asia.

Force Design 2030

The blueprint for this transformation is known as "Force Design 2030." This ambitious plan aims to reshape the Marine Corps to better address future threats, particularly in the Pacific theater. Key aspects of Force Design 2030 include:

• Shedding legacy equipment like tanks
• Investing in new technologies and weapons systems
• Creating new unit structures
• Emphasizing distributed operations across vast distances
• Enhancing long-range precision strike capabilities

New Weapons and Capabilities

To execute its new strategy, the Marine Corps is acquiring and developing several cutting-edge weapons systems:

Naval Strike Missile (NSM) and NEMESIS

The Naval Strike Missile, developed by Norwegian company Kongsberg, forms the core of the Navy Marine Expeditionary Ship Interdiction System (NEMESIS). This weapon gives Marines the ability to threaten enemy ships from coastal positions up to 160 miles away.

Key features of the NSM include:

• High subsonic speed (approx. 715 mph)
• Low-altitude sea-skimming capability
• Stealthy design to evade detection
• Ability to navigate around obstacles and change course mid-flight
• Effective against both naval and land targets

The NEMESIS system mounts these missiles on remotely operated Joint Light Tactical Vehicles (JLTVs), creating highly mobile and concealable coastal defense batteries.

Expeditionary Directed Energy Counter-Swarm (XEX) System

To counter the growing threat of drone swarms, the Marines are adopting the XEX system. This high-powered microwave weapon can disable multiple unmanned aerial vehicles simultaneously by frying their electronics or disrupting their control systems.

The XEX offers several advantages:

• Ability to engage multiple targets rapidly
• Non-kinetic engagement reduces collateral damage
• Effective against various aerial threats, including cruise missiles
• Highly mobile platform

Marine Air Defense Integrated System (MADIS)

The MADIS combines multiple air defense capabilities into a single, mobile platform. It includes:

• 30mm chain gun
• Stinger missiles
• Electronic warfare systems

This integrated approach allows Marines to defend against a wide range of aerial threats, from drones to low-flying aircraft.

New Unit Structures

To effectively employ these new weapons and tactics, the Marine Corps is creating new types of units:

Marine Littoral Regiments (MLRs)

The cornerstone of the Marines' new structure is the Marine Littoral Regiment. These units are designed for distributed operations in coastal and island environments. Each MLR consists of:

• Littoral Combat Team (LCT): Provides anti-ship capabilities
• Littoral Anti-Air Battalion: Focuses on air and missile defense
• Logistics Battalion: Ensures sustainment in austere environments

Three MLRs are planned, with two already established from existing Marine regiments.

Changes to Reconnaissance Capabilities

In a controversial move, the Marine Corps is replacing traditional Scout Sniper platoons with new 26-Marine Scout platoons. This change aims to provide more comprehensive intelligence, surveillance, and reconnaissance (ISR) capabilities to infantry battalions.

Tactics and Operations

The new Marine Corps structure and equipment are designed to support a specific operational concept in the Pacific theater:

Expeditionary Advanced Base Operations (EABO)

This concept envisions Marines rapidly deploying to small islands or coastal positions to establish anti-ship and anti-air capabilities. Key aspects include:

• Quick deployment and set-up of missile batteries and air defenses
• Ability to threaten enemy naval and air assets across vast distances
• Frequent relocation to avoid detection and targeting
• Sustained operations with minimal logistical support

First Days of Conflict

In a potential conflict, MLRs would likely be among the first units deployed. Their mission would involve:

1. Rapidly inserting into strategic locations via aircraft or ships
2. Quickly establishing missile and air defense systems
3. Denying enemy access to key maritime chokepoints
4. Disrupting enemy timelines and forcing resource diversion
5. Providing intelligence and targeting data for other U.S. and allied forces

Logistics Challenges

Sustaining these distributed operations presents significant logistical hurdles:

• Need for pre-positioned supplies on various islands
• Requirement for rapid, low-signature resupply methods
• Importance of units operating with minimal support for extended periods

Recent exercises like Balikatan in the Philippines have focused on testing and refining these logistical concepts.

Controversies and Criticisms

The Marine Corps' transformation has not been without its critics, including some high-profile retired officers:

Concerns from Former Leaders

A group of retired generals, including all living former Commandants, have expressed reservations about Force Design 2030. Their concerns include:

• Over-reliance on long-range precision strikes
• Neglect of traditional combined arms capabilities
• Potential vulnerability of distributed small units

Specific Criticisms

Retired Lieutenant General Paul K. Van Riper has been particularly vocal, calling the concept of using MLRs to attack Chinese ships "dumber than dirt." He argues that:

• Chinese ships could simply stay out of range of Marine missiles
• Slow-moving amphibious ships used to deploy Marines would be vulnerable
• The concept risks repeating historical failures like Wake Island in World War II

Wargame Results

A 2023 wargame conducted by the Center for Strategic and International Studies raised concerns about the viability of MLR operations. Key findings included:

• Difficulty in resupplying MLRs once conflict begins
• Risk of MLRs being reduced to standard infantry units without their specialized equipment

Loss of Scout Sniper Capabilities

The decision to replace Scout Sniper platoons has faced criticism from within the sniper community. Arguments in favor of retaining these units include:

• Unique combination of precision fire and reconnaissance capabilities
• Ability to provide human intelligence in situations where technology may be limited or compromised

Conclusion

The U.S. Marine Corps is undertaking a bold and controversial transformation to meet the challenges of potential conflict in the Pacific. While the new weapons, units, and tactics offer promising capabilities, they also present significant risks and unknowns.

Key takeaways:

1. The Marines are refocusing on their naval roots and preparing for distributed operations in maritime environments.
2. New weapons like the Naval Strike Missile and XEX system provide long-range anti-ship and counter-drone capabilities.
3. Marine Littoral Regiments represent a new type of unit structure designed for rapid deployment and sustained operations in contested areas.
4. The transformation faces criticism from some retired leaders who worry about the loss of traditional capabilities.
5. Logistical challenges and the ability to sustain distributed operations remain significant hurdles.

As tensions in the Pacific continue to simmer, the effectiveness of the Marine Corps' new approach remains to be seen. The success or failure of Force Design 2030 could have far-reaching implications for U.S. military strategy and the balance of power in the region.

Only time will tell if this radical transformation will enable the Marines to maintain their reputation as an elite fighting force in the face of 21st-century threats. As the situation evolves, military planners, policymakers, and observers worldwide will be watching closely to see how the "First to Fight" adapt to the changing nature of warfare in the Pacific.
