CAMP PENDLETON, Calif. – A half-dozen amphibious fight autos swam via calm morning seas and rolled onto Camp Pendleton Marine Corps Base’s Purple Seashore earlier this month. The ACV crews joined a number of others that Navy air-cushioned touchdown craft had already ferried from dock touchdown ship USS Pearl Harbor (LSD-52) a number of miles offshore.
The seaside landings by ACVs and LCACs had been a show of ship-to-shore integration and amphibious operations throughout train Metal Knight 25. The annual 1st Marine Division-led occasion is a key train for the West Coast-based I Marine Expeditionary Drive. This 12 months’s iteration additionally included U.S. third Fleet and tenth Air Drive models.
For the ACV crews from Camp Pendleton-based third Assault Amphibian Battalion, the coaching marked one other goal towards their purpose of deploying and doubtlessly preventing their autos abroad. The battalion, which trains and prepares car crews to deploy with the Division and I MEF process forces, was the primary unit to area the eight-wheeled ACV, in 2020 to exchange its older tracked amphibious assault autos, or AAVs.
Cpl. Roberto Montelongo sat inside his ACV for a Navy LCAC journey towards the seaside in a ship-to-shore show of naval integration through the annual train Metal Knight 25. The ACV operator had spent 5 days aboard San Diego, Calif.-based Pearl Harbor, his first time at sea with the Navy. Again ashore, he thought of when he deploys subsequent 12 months to Okinawa, Japan. It will likely be his first tour abroad.
“I’ve been eager to go for 3 years, then I by no means had the chance,” Montelongo stated. “I’ve been prepared for an journey.”
He initially educated to be an AAV operator simply as “third Tracks,” as many nonetheless name the battalion, started transitioning to the ACV.
“We preserve the Marine Corps amphibious,” he stated of the autos. “So it’s a terrific job to have, and I hope it sticks round.”
The ACV didn’t impress him at first, he added, however the extra he operates it, “the extra comfortable I type of really feel with it.”
The previous 5 years has seen a gradual roll-out and employment of the ACV. This fall, the 26-ton AAVs ended a 53-year run when the Marine Corps formally retired the autos throughout a Sept. 26 ceremony at Assault Amphibian College at Camp Pendleton.
A number of incidents in 2022 prompted fielding delays, extra testing, evaluations and open-water restrictions and modifications on the ACV schoolhouse. ACVs arrived within the Pacific simply final 12 months. Camp Pendleton-based fifteenth Marine Expeditionary Unit and its Battalion Touchdown Workforce 1st Battalion, fifth Marines had been the primary to deploy with an ACV platoon. Its ACVs confirmed its new fight capabilities to Japan-based III Marine Expeditionary Drive throughout train Balikatan within the Philippines. A couple of months later, III MEF acquired its first autos. This 12 months, the primary ACVs built-in into Okinawa-based thirty first MEU’s predeployment coaching and workout routines, which included Talisman Sabre 2025 in Australia.
The ACV is a crucial ship-to-shore connector for Marine Corps floor forces, particularly within the Pacific the place army officers and analysts anticipate battle throughout the contested islands.
A contingent of Pacific-area army officers observing the Dec. 6 seaside raid mirrored the excessive worth of the ACV’s capabilities and presence within the western Pacific. Officers from Philippines and South Korea had been amongst those that joined commanders of the Marine Corps’ West Coast-based infantry division, logistics group and air wing on a bluff at Purple Seashore. In addition they checked out the Marine Corps’ latest ACV-C, a command-and-control variant that would supply key communication hyperlinks for forces preventing the multi-domain struggle.
The Marine Corps is greater than midway via its ACV fielding, having acquired in September the three hundredth car, which was delivered to 2nd Assault Amphibian Battalion at Camp Lejeune, N.C. Marines with the battalion’s Alpha Firm accomplished at-sea naval integration coaching this month off the coast of North Carolina.
Latest ACV is a ‘Sport Changer’
Together with the ACV-C, the service is fielding a personnel variant (ACV-P), a weapons variant (ACV-30) and a restoration variant (ACV-R). Earlier this month, the Division of Protection awarded a $184.4 million contract to Michigan-based BAE Techniques for the ACV-30, which encompasses a 30mm gun and remote-controlled turret weapons system.
“That’s a giant deal,” stated Maj. Gen. Thomas Savage, the first Marine Division commander. “That provides us added fight functionality, and also you struggle the factor like a preventing car, vice only a transport car. It’s going to be a sport changer.”
For the Marines, the ACV-30’s arrival can’t come quickly sufficient.
“It’s a terrific device when you will have a platform like ours that may land with a stabilized turret, can shoot on the transfer within the water, can shoot on the transfer on land, and it brings heavy machine weapons just like the .50 caliber machine gun or the MK-19 40-millimeter grenade launcher,” stated Lt. Col. Fred Monday, the third Assault Amphibian Battalion commander.
The stabilized turret isn’t on LCACs or touchdown craft models, he famous.
“So giving that possibility for somebody to land on a seaside and figuring out that we will maintain that seaside, like we did at present, is totally essential.”
The brand new ACV-C variants, when outfitted with satellite tv for pc and radio communications, will present cell C2 nodes for battle staffs within the hub-spoke-node idea of expeditionary superior base operations throughout the Indo-Pacific, Marines say. The ACVs will present voice, information and a few e-mail capabilities.
“As we go from ship to shore, there at all times must be a communication pathway from the car itself again to ourselves after which to our increased headquarters or adjoining models. We simply provide and complement that,” stated 1st Lt. Brandon Bennett, third AABn communications officer.
Every ACV platoon is getting one or two of the autos, he stated.
“The significance of it falls in understanding the theater during which we’re going to function it,” Bennett stated. “We’re not going to be working within the desert. We’re going the place it’s extra island-chain campaigns. We have to bounce from island to island. How will we try this? Ship (to) shore. What platform are we going to make use of? ACV. And actually, I’m simply thrilled and comfortable to be part of that.”
ACVs operationally targeted

5 years into fielding the ACV, third AABn is reaching its stride as an ACV operational unit.
“That battalion is busy, and so they’re busy [keeping] these autos operating,” stated Savage, the division commander. “Proper now, we’ve acquired back-to-back MEUs developing within the common deployment cycle, and Fred Monday and his guys are working arduous.”
The battalion had been “all in” to get the preliminary ACV platoon educated and licensed to deploy with the fifteenth MEU, Monday stated, including “they crushed it.”
“We’ve met each International Drive Administration requirement that’s been assigned to the battalion, plus some,” Monday stated.
On common about 400 members of the 1,100-member battalion are forward-deployed or dedicated to a MEU or supporting the MEF, he stated. The remainder are both within the coaching cycle or again with a headquarters factor.
The battalion presently has 5 GFM components coaching for deployments. These embody ACV platoons coaching with 1st Battalion, 1st Marines and with 2nd Battalion, 4th Marines.
“Not solely do I’ve these 5 necessities to go assist Okinawa with thirty first MEU and the West Coast MEUs, however we even have components which can be coaching for different deployments, getting on naval delivery and supporting different operations, actions and pursuits for the division,” he stated. “It’s a full-scale manufacturing, and the Marines are keen as a result of they’re truly getting again into the struggle and doing what they need to do… to nonetheless serve their nation, and so they’re doing a fairly rattling good job.”
ACV battalions, sometimes, prepare and certify crews to deploy as platoons or corporations quite than as a full battalion. Metal Knight 25 provided third Tracks employees the prospect to get boots out to the sphere.
“The final time we introduced the battalion out was in 2018,” stated Monday. “So now we’re truly coaching the place all my battalion employees is getting the correct reps and units – not in a cubicle, however within the discomfort of residing beneath the celebs, [sleeping] on an ISO mat the place your again hurts and your shoulder hurts if you get up. Nevertheless it’s good that the entire employees is studying the best way to do what we’d do when the time comes, if we have now to go to conflict.”
Making use of Classes

Security requirements are amplified within the Assault Amphibian Coaching and Working Procedures Standardization (AATOPS) guide.
“Each group is evolving – it’s studying and it’s rising,” Monday stated. “We truly put down numerous classes discovered and switch them into classes utilized. So all of the issues we discovered from – you’ll be able to argue some missteps years in the past the place we simply didn’t know – these have been utilized into what we name the AATOPs.”
All crew are educated and examined on AATOPS, much like Navy aviation’s NATOPS.
“The place we could have a misstep – the place a car could break down within the water or could break down on land – I’m very assured that when these unhealthy days occur, the crew is ready to rise to that event as a result of they’re educated for it,” Monday stated.
It may possibly take a 12 months to totally prepare and put together ACV crews to deploy. That features submerged car coaching coaching and surf qualification, the latter which includes bailing out of an ACV and swimming 500 meters via the surf zone.
The concentrate on security coaching isn’t only for ACV crews.
“Relating to the built-in coaching that we do with the embarked infantry ashore in addition to afloat and with the Navy, we have now a deliberate coaching pipeline,” stated Monday, who earlier than taking battalion command led the Transition Coaching Unit and helped develop and implement coaching, analysis, certification and requirements for the group. “There’s the identical normal – one normal – for anybody getting in a car, and it’s the usual of with the ability to know that I’m assured and so they’re assured in their very own potential to get out.”
Anybody driving in an ACV – infantry Marines, fight digicam, corpsmen, battle employees – will get security and familiarization coaching. That coaching consists of working via ACV operations and egress procedures in Camp Pendleton’s protected boat basin and a Water Built-in Coaching Package deal for infantry and different passengers that features a swim ashore drill.
Troop commanders and embarked Marines tasked because the “rear egress operator” are additionally educated on opening hatches and working the rear ramp and guaranteeing everybody will get out. Everybody participated in courses on the “set off traces,” or “what proper appears like (and) what proper doesn’t appear to be,” similar to water rising off the deck inside an ACV, Monday stated.
Marines with third AABn often prepare with battalion touchdown groups’ mechanized corporations on the boat basin’s ramp and within the water. That point in and round an ACV has the additional benefit of familiarizing Marines and different passengers in regards to the Corps’ latest amphibious car.
“I’m fairly certain they’re going to place that stuff on Fb later once they get residence, saying #ACV coaching,” Monday stated. “However they get an opportunity to actually go do the factor they signed up for…. The possibility for them to be in a mechanized firm is fairly badass, the place you get to be within the effectively deck, splash out for the again of the ship, land on the seaside – and so they can cost their cellphone alongside the best way, as a result of they’ve acquired energy retailers within the ACV.”

The battalion commander spent a part of Metal Knight 25 aboard Pearl Harbor, the place his govt officer remained and deliberate for the ship-to-shore operations with the ship’s captain and crew guided by the Moist Nicely Operations and Ship-to-Shore manuals.
That is consistent with the AATOPS requirement “to make sure that the blue-green staff is totally built-in,” Monday stated.
It features a 15-line report that’s accepted by the Marine commander and the ship’s captain, and it green-lights the operation and an built-in execution guidelines and built-in situations guidelines to make sure that earlier than Marines go within the water, they’re all set. It additionally requires blue-green communications, command and management stay clear and fixed – together with on the bridge, in fight and within the effectively deck – all through the operation.
“It lets us know what they’re accountable for amphibious planning issues, tactical issues ashore, and the way we deliver it collectively. So if we will get the staff to that stage, that’s how we function inherently secure shifting ahead,” Monday stated.
Savage, the division commander, acknowledged that extra work stays within the Marine Corps’ transition from the AAV and amphibious and mechanized integration of the ACV.
“We acquired the system operating,” he stated, including, “There’s nonetheless numerous work to do with that… You already know, we stopped doing [mechanized] integration for some time, we’ve slowed down with the sundown of the AAV and all the issues we had with that build up of the ACV.”
The ACVs, Savage stated, are tough to maintain maintained correctly, and the battalion doesn’t carry as a lot because the AAVs used to hold. “However we’ve actually come a great distance in terms of what we’re doing within the water with these issues and safely working them in real-world tactical situations,” Savage stated. “We’ve acquired some work to do on the bottom aspect, however they’ve acquired some fairly good functionality.”
Marines who operated the tracked AAVs say it’s trickier driving the ACV inside a ship or a fight city, noting the wheeled base doesn’t permit for simple maneuver via tight areas.
However the ACV crews are dedicated to creating it work, Savage stated. Concurrently with Metal Knight, Marines with eleventh MEU’s Battalion Touchdown Workforce third Battalion, fifth Marines performed ACV integration and surf coaching in preparation for his or her upcoming deployment.
“It’s like many different new programs that you just get. You’ve got glitches and also you attempt to determine issues out if you area them. However day by day we’re studying extra about that car. We’re getting higher,” Savage stated.
