The President of the United States of America takes pride in presenting the Navy and Marine Corps Medal (Posthumously) to Aviation Machinist’s Mate Airman Apprentice Michael S. Zambo, United States Navy, for heroic conduct on the afternoon of 5 October 1963 while swimming with two companions at Jacksonville Beach, Florida. Caught in a treacherous undertow which abruptly swept him and his two companions out into deep water, Aviation Machinist’s Mate Zambo, after a long and exhausting struggle against the current and surf, managed to reach the safety of shallow water. Observing that his friends were still struggling to reach the shore, he plunged back into the surf in a valiant attempt to assist them, despite his own exhausted condition.
