Why do Marines needs to buy C models? The Marine Corps doesn't get much out of a Squadron that is part of a CAG in our MAGTF. Some old guys around here have enlightened us that the Marine Corps presence on carriers is pretty much because the Navy wants more squadrons but doesn't want to pay for them. The Corps buying C models will create huge costs in training, maintenance, parts etc.... You would essentially be creating a whole new airplane. No other service is going to operate two versions of the airplane. Why should we?
