Final month, the Okinawa, Japan-based twelfth Marine Littoral Regiment stood up the final of its subordinate models, pulling a storied fight infantry battalion into the fold of a contemporary front-line Marine Corps pressure within the Western Pacific.
Because the second of the Marine Corps’ three deliberate littoral regiments, the twelfth MLR is tasked with working alongside Japanese Self-Protection Forces if battle erupts within the area, notably with China. Its main missions – together with defending naval and maritime forces from adversary missile and drone assaults and hanging the adversary, no matter warfare area – are largely centered on the regional risk of China.
Since its redesignation in 2023 from the twelfth Marine Regiment, twelfth MLR has constructed a formation that features the twelfth Littoral Anti-Air Battalion, twelfth Littoral Logistics Battalion, most not too long ago, and the twelfth Littoral Fight Workforce that fashioned from the infantry models of 1st Battalion, 4th Marines. Its personnel and gear buildings will intently mirror that of the Hawaii-based third MLR, which is aligned with coaching and partnering with the Philippines.
“None of these battalions will deploy as a singular unit,” Col. Peter Eltringham stated Tuesday throughout a media name from the Pentagon. “We successfully break them aside right into a system of programs, a workforce of groups, to place small models into austere, maritime key terrain.”
The twelfth MLR will develop from its roughly 1,300 Marines and sailors to a pressure of two,000 by 2027, when the regiment is predicted to achieve full operational functionality, Eltringham stated.
Each littoral regiments are a part of the Marine Corps’ so-called stand-in pressure, which beneath its Power Design idea are deployed and working throughout the first island chain. That’s a geographic space fast to China the place navy consultants anticipate China’s Folks’s Liberation Military would maneuver and assault, resembling in a state of affairs to retake Taiwan or contested isles within the South China Sea.
For the twelfth MLR, the Marines’ mission can be “to grab and defend maritime terrain, develop joint sensor and [command-and-control] networks and set up long-range precision fires, in help of sea denial and sea management,” Eltringham stated. They might function within the area’s contested maritime area, conducting distributed maritime operations whereas integrating with allies, companions and the remainder of the U.S. joint pressure.
So the regiment’s coaching is concentrated largely on working within the area and constructing on their warfighting capabilities throughout all of the warfare domains.
“We function in small, dispersed however networked formations so we are able to present command and management, sustainment, strike and sensing belongings,” Eltringham stated. “For us, that’s within the Sakishima islands,” he stated.
The chain of islands present area for Marines and sailors “to rehearse maritime area consciousness, and [we] be sure we’re using and mixing functionality” with their counterparts of the JSDF, he added.
Final summer time, throughout train Resolute Dragon 24, Marines with the twelfth MLR deployed with the superior AN/TPS-80 Floor/Air Job Order radar, to Camp Yonaguni, a Japanese Floor Self-Protection Power base on Yonaguni, Japan’s westernmost isle. Throughout Eager Sword 25 in October, they deployed G/ATOR at Camp Ishigaki “to reinforce air surveillance and focusing on capabilities,” stated 1st Lt. Sarah Bobrowski, a regimental spokeswoman.
The yr forward can be one other busy one for the littoral regiment, which was twelfth Marine Regiment earlier than its redesignation. The twelfth Marines was an artillery regiment amd fell beneath the Japan-based III Marine Expeditionary Power and third Marine Division, but when first fashioned within the late Twenties as an infantry regiment, led by Lt. Col. Jesse F. Dyer and with numerous components beneath Brigadier Common Smedley D. Butler and third Marine Brigade in China. That’s in response to the Marine Corps’ 1972 publication, “A Transient Historical past of the twelfth Marines.
As combating expanded within the Pacific theater, twelfth Marines reactivated in 1942 beneath the command of Col. John B. Wilson. Wilson led the regiment by way of a number of operations, together with Bougainville, Guadalcanal, Guam and Iwo Jima. He later was honored with the Marine Corps naming the desert area encampment — Camp Wilson — at Marine Corps Air Floor Fight Heart at Twentynine Palms, Calif. Deactivated in 1946, twelfth Marines once more reactivated in 1952 and a number of components deployed to fight in Vietnam.
The twelfth MLR’s fight workforce, fashioned by 1st Battalion, 4th Marines, has an extended and storied historical past. Fashioned in 1911, 1/4 first noticed motion in 1916 within the Dominican Republic, in response to its official historical past, and earned its “China Marines” moniker whereas working from Shanghai and the Philippines earlier than the Pearl Harbor assault. The battalion re-formed on Feb. 1, 1944, and fought within the bloody battles of Guam and Okinawa.
In 1965, 1/4 deployed to Vietnam and noticed fight by way of a number of operations within the I Corps area and later joined in evacuations from Vietnam. The battalion deployed aboard Navy ships for Operation Desert Storm in 1990-1991 and fought on the bottom throughout Operation Iraqi Freedom in 2003 and once more deployed to Iraq in 2004, 2006 and 2008.
twelfth MLR’s Strategic Function
Yonaguni and Ishigaki are a part of the Sakishima Islands, which fall beneath Okinawa Prefecture. The islands stretch 60 to 150 miles east of Taiwan and are south of Japan’s uninhabited Senkaku islands which are contested by China and Taiwan.
Their location poses one thing of a entrance row seat to actions alongside the South China Sea and is squarely throughout the first island chain, the place U.S. and allies’ navy forces are poised because the stand-in pressure and deployed there would discover themselves contained in the weapons engagement zone if battle erupts with the Folks’s Republic of China.
The twelfth MLR “is smart given the vulnerability of enormous, mounted bases to PRC strike. And relying on the dispersal plan, having self-deployable, multi-domain models is helpful if they’ll benefit from the archipelagic atmosphere,” Jeffrey Hornung, a senior political scientist and Japan lead for RAND’s nationwide safety analysis division, informed USNI Information. “It is because this stand-in pressure is designed to conduct a number of crucial missions that the Joint Power would require.”
Coaching and working in that maritime atmosphere requires clear agreements with Japan that outline parameters for U.S. forces and, amongst different issues, the supporting logistics required to reply and help these models in a battle with China, he stated.
“With the intention being to have them function throughout the competitors continuum, I believe the large query can be ‘when’ the MLR can transfer. There are a lot of laws and agreements in place concerning what U.S. forces can do outdoors of their bases and once they can do it,” Hornung stated by e mail. “If one of many advantages of an MLR is its means to function in small, scattered areas, that can require settlement by each native authorities and the central authorities for when U.S. troopers can do that. Relying on what ‘scenario’ Tokyo declares, this motion may very well be delayed, thereby negating an early mover profit for the MLR.”
Eltringham stated he’s centered on strengthening the MLR’s relationship and interoperability with the JSDF. “We’re joint prepared, bilateral organizations at our core,” he stated. The MLR established a bilateral floor tactical coordination middle that’s built-in throughout warfighting capabilities, together with communications, fires and sustainment.
The regiment continues to construct on its capabilities for its two warfighting ideas: expeditionary superior base operations and littoral operations in contested environments. “Once we set up expeditionary superior bases, we transfer to these areas, after which we are able to proceed to additional distribute [forces] from these superior bases as we create that cycle of motion and of maneuver,” the colonel stated.
Bilateral workouts with Japan, joint coaching and common unit-level coaching – together with the recurring Resolute Dragon and Eager Sword train collection – are constructing the regiment’s warfighting capabilities. “The problem is ensuring we’re doing the timing and the sequencing accurately, by way of the joint train lifecycle … and throughout the yr,” Eltringham stated, including that “we’re getting higher and stronger because the months move.”
The twelfth MLR did joint medical evacuation drills and skilled with Japanese forces at Camp Yonaguni to construct an expeditionary medical response, in response to Bobrowski, the regimental spokeswoman. It continues to coach recurrently with the JSDF she stated, and can be part of them once more for the annual bilateral train Resolute Dragon 25 later this yr.
Layers of Logistics
A battle with China within the area will problem the flexibility of MLRs to help and resupply its small forces dispersed throughout the area. So commanders are relying on layers of help from plane – resembling U.S. and Japanese C-130 and C-17 transports and air-delivery drones – and from floor vessels, together with autonomous unmanned vessels. “The logistics related to which are completely crucial,” Eltringham stated.
In a battle, he stated, “the problem can be no matter their particular person job is goes to be sophisticated by the adversary’s means to affect it.”
“If they’re sensed, then they properly might turn into a goal – so the challenges are very actual, notably in a drone-swarm kind of state of affairs or throughout the weapons engagement zone of enemy theater ballistic missile and issues like that,” he added. “I want them to be survivable, I want them to be versatile and I want them to consider and be adaptable to different means.” That may embrace Marines discovering methods to get an Autonomous Low-Profile Vessel, or ALPV, in to carry provides when one other technique of supply isn’t doable, he stated.
“What we owe these Marines is the flexibility to coach on that gear and be capable to adapt as shortly as doable,” Eltringham stated. They could find yourself “in a scenario the place we’re with out communication or with out logistical resupply inside a time period. So these Marines have gotten to be prepared to stay sustainable … for extended durations of time.”
To get them to assume, act and plan for these prospects, the MLR is focusing coaching on educating Marines to work regionally, throughout the island or jungle atmosphere they discover themselves in, he stated, in order that they study to maintain and subsist “till we are able to get to them.”
Equipping the MLR
As envisioned, littoral models can be disaggregated throughout an unlimited maritime area, and the Marine Corps is relying on superior applied sciences and programs to provide Marines and sailors the warfighting capabilities they want – and throughout all warfare domains. By dispersing models, Eltringham stated, “we are able to cowl extra floor. We will create bigger sensor networks … and strike-capable networks and ranges.”
To organize for a possible battle, the twelfth MLR is getting outfitted with a number of the Marine Corps’ newest superior gear, together with superior radar programs, anti-ship missiles, and resupply drones. That features the Navy/Marine Expeditionary Ship Interdiction System, or N/MESIS, which might be employed alongside Japan’s surface-to-surface missile functionality. The third MLR has been fielding the system, he stated, and “it’s one thing that we’ll be receiving over the course of the following couple of months.” The regiment’s twelfth LCT finally will get 18 N/MESIS, Army.com reported final month.
“All of those improve our lethality, our survivability and our sustainability,” Eltringham stated. The G/ATOR programs “enable us to carry adversaries in danger and pressure laborious selections.”
“Expertise, nevertheless, doesn’t change the Marine decision-making,” he stated, “but it surely enhances it.”
The MLR’s components, together with the twelfth Littoral Anti-Air Battalion, proceed to area gear and kit.
The Marines are centered on elementary fight fieldcraft and on core technical abilities, together with air surveillance and early warning, air management, and ground-based air protection. “These are advanced talent units, and our Marines are laying the inspiration now in order gear arrives, we’re able to make use of it successfully,” Lt. Col. Scott Caton, the twelfth LAAB commander, stated by e mail.
The battalion is engaged on plans with the U.S. Navy, Military and Air Power for upcoming joint coaching, which is able to “improve considerably sooner or later,” he stated. Marines are also coaching with the Okinawa-based Marine Air Management Group 18, “reinforcing our integration throughout the Marine Air Command and Management System and sharpening the sting of our operational readiness.”
The Marine Corps desires its frontline MLR models to be much less predictable and fewer identifiable than its conventional expeditionary forces have been.
“I need them to be small groups. I need them to be laborious to seek out,” Eltringham stated. They are going to be outfitted with networked capabilities to gather and share intelligence, conduct and help strikes on targets, and do command and management for his or her Marines or to help others.
“Success within the littorals requires empowering small agile models to allow them to be capable to make fast selections on the tactical stage,” he added, noting that littoral warfare “is quick, it’s fluid and it’s sophisticated by a number of components.” Points like an adversary’s surprising actions or a break in speaking with greater command can problem junior leaders.
It’s essential to put belief on subordinate leaders and empower them to take initiative and exploit the adversary’s gaps as they come up, Eltringham stated, and guarantee they “have the suitable authorities to have the ability to execute once they don’t have the flexibility to speak safely with greater headquarters or adjoining models.”
A battle within the contested maritime atmosphere “is all about pace, tempo, adaptation and sustainability,” he stated, and in the end “to pressure our adversaries to make very, very tough selections.”
