The President of the United States of America takes pleasure in presenting the Navy Cross to Private First Class Timothy S. Guarino (MCSN: 2484801), United States Marine Corps, for extraordinary heroism while serving as a Machine Gun Ammunition Man with Company G, Second Battalion, Ninth Marines, THIRD Marine Division (Reinforced), Fleet Marine Force, in the Republic of Vietnam on 1 June 1969. Company G came under a vicious ground attack by a determined hostile force utilizing satchel charges, automatic weapons fire and rocket-propelled grenades. While resolutely defending his position in a sector of the perimeter which had been penetrated by the enemy, Private First Class Guarino observed a wounded companion fall in a position dangerously exposed to the enemy advance. Completely disregarding his own safety, he fearlessly crossed the fire-swept area and carried his injured comrade to a place where medical aid was available. As he was assisting in treating the casualty, an enemy hand grenade landed beside the Corpsman and the wounded Marine. Fully aware of the possible consequences of his actions and thinking only of the safety of his companions, Private First Class Guarino unhesitatingly knocked the Corpsman to the ground beside the wounded Marine and valiantly threw himself over their bodies, thus absorbing the full force of the grenade’s detonation and sustaining extensive wounds. His heroic and bold efforts inspired all who observed him and saved the lives of two comrades. By his courage, selfless concern for his fellowman and unwavering devotion to duty in the face of grave personal danger, Private First Class Guarino upheld the highest traditions of the Marine Corps and the United States Naval Service.
