Marine Corps Invests in Drone Truck-Based Ship-Killer Missile as it Ditches Some MRAPs The Navy Marine Expeditionary Ship Interdiction System can launch naval strike missiles from the back of a modified Joint Light Tactical Vehicle to destroy targets on land or at sea. (U.S. Navy) 28 May 2021 The Marine Corps wants to ramp up its ground combat and long-range fires capabilities with a burst of fresh funding -- and it's getting rid of more than $9 million worth of old gear to help pay for it. The White House budget request for fiscal 2022 totals $47.86 billion for the Marine Corps, up from $45.1 million last year. That's despite plans to reduce the force by 2,700 Marines, from 181,200 to 178,500.
