A Kaneohe Marine who died while saving fellow Marines from a grenade blast during the 2004 battle for Fallujah in Iraq was honored during a ship-naming ceremony at Naval Base San Diego last week.  The Navy is naming an Arleigh Burke-class destroyer after Sergeant Rafael Peralta, a member of the 1st Battalion, 3rd Marine Regiment based at Marine Corps Base Hawaii. Destroyers are traditionally named after Navy heros. Peralta was fatally shot during house-to-house fighting during the second battle of Fallujah. Kaneohe Marines who entered the house with Peralta said his last act was to pull an enemy grenade to his body after he had been wounded. They said the act saved their lives.
