Charles was not aboard the KIDD for long, though, before he transferred to Portland, Maine, on May 31, 1943.  This was the first of several transfers in his naval career.  On July 08, 1943, he was sent to the USN dispensary in Argentia, Newfoundland, Canada.  From there, he went to Norfolk, Virginia, on August 13, 1943.  He was later transferred to Pearl Harbor, Hawaii, on September 14, 1944.

It was not until December 19, 1944, that Charles was transferred back aboard the KIDD where he served as a Steward's Mate 2^nd class.  When the kamikaze plane struck the KIDD off of Okinawa on April 11, 1945, Charles was struggling with a case of the mumps and was confined to his bunk, located in the Steward's berthing one level below the main deck on the port side, adjacent to the Mess Deck ladder.  The bomb that the plane carried did not detonate inside of the ship but rather was catapulted through the forward fireroom, holing the destroyer and exploding outside the port side hull.  Damaged CO² cylinders stowed on the main deck at the Mess Deck ladder caused secondary explosions, adding to the destruction.  The port side hull and superstructure were sprayed with a deadly hail of shrapnel.  Amidst this man-made hell with explosions above him and beside him, Charles lay sick in his bunk, unable to man his battle station alongside his shipmates.  What became of him is not known.  Charles simply vanished.

In the wake of the attack, Charles Green—along with six others—was listed as Missing In Action.  Of those seven, five were found in the wreckage of the forward fireroom.  Charles and his shipmate John Miller, Jr., remain listed as Missing In Action (MIA) to this day.
