Will someone explain to me where the Amphibious Combat Vehicle fits into Berger's Missile Marine Concept?

 

I like the ACV.

I want the Marine Corps to buy the ACV.

I think the ACV will be the last remaining element of a Marine Corps that is able to seize ground and assault the enemy versus being totally defensive in nature.

Having said that I don't understand where the ACV fits into Berger's Missile Marine Concept.  Can anyone explain it to me cause I'm lost.
