US Marine Corps tanks and a lighter amphibious role

Is the US Marine Corps going too far by removing M1 tanks from its forces?

Not necessarily, provided it retains enough artillery, anti-tank weapons, and mobility; the change shifts it toward an amphibious cavalry role.

Tanks remain valuable whenever their protection and concentrated firepower are genuinely needed. The Marine Corps may cover some tasks with artillery, anti-tank weapons, and mobile armoured personnel carriers, shifting toward an amphibious cavalry model rather than an amphibious armoured force. That lighter structure can work only if the substitute firepower and mobility exist in sufficient quantity. Designing the force too narrowly around one anticipated island campaign could leave it badly equipped for a different commitment, such as an operation in Africa where tanks would again be useful.
