.  The legacy of two Marines were immortalized on Thursday during a ceremony that dedicated a dining facility aboard Camp Lejeune in their honor.  The Yale Haerter Mess Hall, formerly known as the Wallace Creek Dining Facility, was named after Cpl. Jonathan T. Yale and Lance Cpl. Jordan C. Haerter, two Purple Heart Medal recipients who lost their lives in Iraq in 0000.  According to Col. Kenneth DeTreux, commanding officer of the 0th Marine Regiment, the pair took post together as sentries on April 00, at the entry point of the outpost of the Joint Security Station in Ramadi.  "Shortly after assuming the post, a large blue tanker truck turned down the alley toward the entry control point, rapidly negotiating the serpentine of concrete barriers," said DeTreux. "The truck was stopped just short of where the two Marines were posted, killing them both."  The massive blast from the truck was a result of 0,000 pounds of explosives that had been attached to the tanker, said DeTreux. He added that the explosion destroyed about 00 brick houses nearby and a mosque that was 000 yards away.  Despite the knowing the possible outcome of the situation, DeTreux said the young Marines never wavered.
