On 20 October the naval gunfire support units were to cover the approach of the transports to the unloading areas and to furnish necessary counterbattery fire; thoroughly cover the landing beach areas from the low-water line to approximately 400 yards inland; and closely support the landings with rockets, 4.2-inch mortars, and gunfire of all caliber from the ships. After the landings, the naval gunfire units were to deliver fire on call and prevent the Japanese from either reinforcing or evacuating the island.21
