We have joined the 15th MEU (Marine Expeditionary Unit) for an Amphibious Assault

Today’s mission: Gain a beachhead, assault and secure a village with a mixed hostile/civilian population, capture a high value target and secure intelligence. With the 15th MEU at PMINT (PHIBRON [NAVY] & MEU [Marines] Integration.

What does an Amphibious Assault have to do with Aviation? Aside from being supported by Aviation assets, a critical part of the Amphibious Assault is the Landing Craft Air Cushion (LCAC) or “Assault Hovercraft.”

LCACs are operated by pilots, and arguably one of the lowest flying, heavy lifting craft in service today. Stretching it – perhaps just a little. In years to come, expect the America Amphibious Ready Group (and subsequent America class of ships (LHA) that forgo their well deck to focus on deploying aviation assets) to redefine Amphibious Assault.

The Aviation component will move troops deep inland in MV-22Bs, with the support of F-35Bs to assault in contested space, and CH-53Ks functioning as ship to shore connectors hauling significant heavy equipment. Today we look primarily at the seaborne component of amphibious assault. No question seaborne assault will remain a/the significant component of amphibious assault. Regardless, the developing aviation component provides the US Marines with many more options to execute their missions.

On board the U.S.S. San Diego all briefings are complete and mission execution is all that remains. Marines of the 15th Marine Expeditionary Unit (MEU) gather their steroid induced rucks and pack into the tight confines of the Amphibious Assault Vehicle (AAV). Three crew, weapons, support equipment and up to 21 Marines in each AAV. It is tight quarters among team.

The smell of diesel fills the air, the clang of metal on metal and slapping of water on the well deck speaks “go time.” On cue, the ramp, and all hatches of the AAV close tightly and the vehicle is readied for launch. Launch? Yes, launch into the deep blue sea off the back of the San Diego with as much grace as 29 tons on tracks can muster.
Any apprehension (and there must be some) is masked by focus on the mission at hand. We are United States Marines, and this is what we do.

This is the defining mission set for Marines. Amphibious Assault.

This forcible entry from the sea recalls revered Marine battles of the past; Iwo Jima, Guadalcanal, Okinawa – fought in conditions we cannot know. Marines immortalized, their qualities of valor and determination to fight through to the finish now awakened in the hearts of this generation of US Marines.

Today’s mission: Gain a beachhead, assault and secure a village with a mixed hostile/civilian population, capture a high value target and secure intelligence. Location: Red Beach, Camp Pendleton, CA. The exercise is the culmination of PMINT (PHIBRON – MEU INTegration). The PHIBRON (AmPHIBious SquadRON) consists of the U.S.S. America (LHA-6), U.S.S. San Diego (LPD-22) and U.S.S. Pearl Harbor (LSD- 52), otherwise known as the “America Amphibious Ready Group” (ARG).

The 15th MEU is about 4 months deep in their 6 months of deployment workups. Previous phases of the workups focused on individual skills followed by unit skills and included exercises such as Realistic Urban Training (RUT) (article on the 15th MEUs RUT). PMINT is the stage when the ARG/MEU force integrates as a cohesive team, US Marines and US Navy. Lt. Col Richard Alvarez, Executive Officer of the 15th MEU explained, “the most challenging thing we do is integrating all the assets, making them work as a team. Leaving the ship, coming to shore.”

The amphibious assault represents the culmination of PMINT and the transition to the final two months of workups before the ARG/MEU deployment this summer.

The U.S.S. San Diego draws relatively close to shore and the ramp at the rear of the well deck draws down. Go time. One after another the AAVs “launch,” almost disappearing in the water before bobbing up to “float height.” These AAVs may motor but they certainly don’t fly, in fact they barely seem to float, sitting deep in the water ensuring a low profile if targeted. Two waves, one of 5 the other of 6 AAVs are formed. Quick math, and it is clear, hundreds of Marines are incoming.

Overhead we do see some fliers, the 15th MEUs Aviation Combat Element (ACE) is represented by VMM-161 UH-1Y Venom and AH-1Z Viper helicopters. The Venom drops its nose making simulated rocket runs on… us. The Vipers gun turret swivels from side to side – pointing at… us. If the battlefield were real, the outcome of those looks – the last record in your memory bank.

It is tempting to jump to the conclusion that a battlefield scenario would include a massive Naval bombardment and airpower strikes – but it is not that simple. The operational situation would define support levels. On the table, everything from that Naval bombardment and fierce air attack to soften up the shore – to a stealthy approach in the dead of night. The full extent of the ACE (not utilized in this specific exercise) provides even more options such as; distributed assault utilizing MV-22Bs where hundreds of Marines can land hundreds of miles inland and CH-53E Super Stallions can sling support equipment to positions of tactical advantage. As the exercise progresses we see those very MV-22Bs and CH-53Es land in an adjacent area down the beach from the village.

The amphibious assault is just one of 13 mission sets the MEU is “certified” to execute during their deployment. The forward deployed, rapid responding, broadly capable ARG/MEU provide the combatant commander with incredible flexibility and capability. Even if not mission utilized, their mere presence offshore sends a strong message of deterrence.
The AAVs approach the shore and move quickly from the waves, to the beach and on to predefined positions flanking the village. Within moments Marines burst from the confines of the AAVs and move forward with purpose under their own notional covering fire. This assault quickly becomes Military Operations on Urbanized Terrain (MOUT), it is dangerous and dynamic.

Marines must carefully assess surroundings, dynamic threats, and make life and death decisions in an instant.

Around any corner, in any number of buildings the Marines confront notional combatants both in uniform and civilian clothing utilizing a variety of weapons. In cases hostiles “play dead” only to open fire as Marines close, or use civilians as human shields. Throughout the exercise trainers identify issues real-time and miss steps or misfortune generate notional Marine injuries that subsequently require team support, medical attention and evacuation.

With the battle raging in the heart of the village “High Speed, Heavy Lifting” Assault Hovercraft -(officially “Landing Craft Air Cushion” vehicles (LCAC)) FLY ashore to unload numerous Light Armored Vehicles (LAVs) and High Mobility Multi Wheeled Vehicles (HMMWVs – generally known as Humvees). Soon, the village is teaming with Marines. AAVs, LAVS, HMMWVs with devastating firepower create a perimeter around the village to defend from counter attack.

Alvarez emphasized that this specific training event mimicked real world scenario, “it puts Marines in a place where they must differentiate and make decisions.” The workup period is high tempo and relentless. Repeated exposure to intense “real world scenarios” discipline Marines physical and mental skills to respond like muscle memory when on mission.

With PMINT behind them, the final two months of workups remain. 1st Lt. Maida Zheng, Public Affairs Officer of the 15th MEU indicated the next stages as the Composite Training Unit Exercise (COMPTUEX) where the ARG/MEU will exercise assigned mission essential tasks ensuring they are fully prepared for the Certification Exercise (CERTEX). Upon successful completion of CERTEX, the 15th MEU will be officially certified for their Western Pacific (WESTPAC) / Central Command (CENTCOM) deployment with the America ARG.
