With more nations arming themselves with hypersonic and ballistic missiles coupled with drones, it makes amphibious launches extremely difficult due to unpacking and combat readiness factors. They have to land further away now. And as allies refuse their airstrips, it becomes even more important to be self sufficient. If we quit NATO we can use that money saved to build more specialized MEU and carriers, doubling our fleet, and capabilities. Dropping off armor and cargo containers takes a long time compared to the threats window. The job of a lightweight electrified MEU is to remove that threat, and then afterwards provide a supporting cover role for the heavy equipment such as watching for threats to attack helicopters from ground, mountains, and buildings, as they would for a mechanized heavy force. This is why a ground war in today's environment is so difficult. Either start far away and work your way in, or create these lightweight support units. 50 to 100 miles a day is a lot of ground to take in a modern war now a days due to drones mainly.
