Aka, the Japanese island garrison and 鼠輸送 during WWII. We all know what happened.Correct!!!
The new doctrine developed for the USMC, which mandates these LSMs, focuses on deploying independent units of the force in support of the US Navy (secondarily, the USAF) in an attempt to contain or degrade Chinese naval capabilities in the Pacific in case of conflict.
To summarize quite simply, anyone knows that China has built an entire navy and an anti-access and area denial system off its coast to prevent entry. The US wants to have the capability to build an anti-access and area denial system so that the Chinese navy does not go far from its coast in case of conflict. Containment… The LSMs are merely a means of transport and support.
In other words, the Marines will no longer be the force that performs a forced amphibious entry into contested environments; they will bypass these contested territories and land on remote islands to deploy anti-ship systems, creating an anti-access zone for the PLAN.
Amphibious Assault
Operational Maneuver From The Sea: OMFTS
Expeditionary Advanced Base Operations: EABO
Amphibious Assault: This is the classic scenario, where the USMC would be employed as a force aiming for a massive and concentrated attack to capture a beachhead, opening space for a larger force: the US Army. This is where the large support assets they have in the Ready Reserve Force would come in, for example… The USMC's objective is not to "hold the ground."
OMFTS: A rapid and massive operation with large units (like the brigade below), where the USMC maneuvers by kicking down the door, conquering different objectives, which can be both on the beach and inland. Hence the great focus on aircraft, for example.
EABO: Dispersed operations with a large number of small units that can support the US Navy and USAF and degrade or even contain the movements and advance of Chinese forces in the Pacific.
The USMC doesn't want to carry out what they call a "forced entry" into the Pacific. Why? Because more than anyone, they understand the risks. That's where the EABO came from. The LSM is merely a means of transport and support for this doctrine.
The objective is not to take a beach defended by Chinese troops with these means. They will land on a beach and disembark a unit equipped with systems and weapons to harass Chinese forces. Primarily those that could be used to take that particular beach. In other words: the one who would have to carry out a forced entry, operating against A2/AD systems, would be China!

LOA: Littoral Operations Area.
I'm getting increasingly annoyed by the meaningless slang used by the US military.
