Disaggregated Amphibious Ready Groups are gonna need different ships.

Check this out from the Marine Corps Times...

To meet those challenges, the service could put a small special purpose MAGTF on the next generation LXR amphibious ship. While the ship — based on the hull of the Navy's current San Antonio-class amphibious transport dock ships — has space for two fewer landing craft air cushions, it has a much larger flight deck, O'Donnell said.
That provides more capability with air assets, which is significant he said, because Marine forces will be able to disaggregate for distributed operations.
That means it could be used as a "single deployer" floating on its own with a crisis response unit aboard. That closely mirrors comments made by Lt. Gen. Kenneth Glueck, commanding general of Marine Corps Combat Development Command, who said in September that in 2015 he would explore the possibility of placing crisis response units on Navy mobile landing platform ships.
It give Marines a faster response time when carrying out missions like the evacuation of the U.S. Embassy in South Sudan, about a year ago, or the one in Libya in July. The Marines had to deploy from Móron, Spain. While they were able to successfully complete their missions, they had to fly long distances to do so.
Distributed operations, as implied by the theme of this year's symposium — Surface warfare: Distributed Lethality, Going on the Offensive — will define the Marine Corps' future.

We're gonna need different types of amphibious ships to make this concept work.

If we're talking about amphibious ships becoming single deployers then we need something like the Mistral and not the LXR.

The wing has won.

*  It just occurred to me that the MEU as we've known it is probably dead.  Infantry Battalions will simply be broken up to be farmed out to SPMAGTF's and mini MEUs aboard single deployer ships.  Someone said that the reason why the Marine Corps performed so well in the Korean War while the Army suffered is because they  formed adhoc combat teams that were not able to bring combined arms to the fray in the same way as USMC units.
