The Marines got rid of their tanks because they are refocusing on actual amphibious warfare, say Pacific island landings against China, and the current M1 is so heavy that a giant LCAC can deliver only *one* of them to shore at a time. One.
The Marines are likely to be able to borrow tanks (and crews) from the Army if they need them for an operation, and they are also likely to buy some of the new light tanks the Army is looking at getting now that the Abrams isn’t tactically airmobile any more.
Yup. Trucks with Abrams going out of 29 palms up to barstow and trucks coming in with ACVs.
