Input: Consider Input: Oceanside, New York (CNN) -- Deployed to a volatile outpost in southern Afghanistan where U.S. Marines routinely face a mix of skirmishes and hidden explosives, Greg Buckley Jr. sensed that an attack was imminent. And he knew that it would come from within. The 21-year-old Marine was posted to Garmsir in Helmand Province, where he was training local security forces as part of NATO's planned withdrawal in 2014. It was during a static-filled phone call to his father over the summer that the Long Island native mentioned a run-in he had with an Afghan trainee while on guard duty. NATO releases details of brazen raid on base in Afghanistan . The encounter was the first in which the Buckley family's eldest son seemed to sense something was wrong, according to what he told his family in phone conversations and a letter. "The guy turned around and said to Greg, 'We don't want you here. We don't need you here,'" his dad said. "Greg turned around again and said, 'Why would you say that?'" according to Greg Buckley Sr. But the trainee apparently wouldn't relent, repeating the phrases for hours over the course of a night in which the young Marine was on guard watch. "Greg said, 'I thought I was going to lose my mind,'" his father said. "Pitch black out, and all he kept saying over and over again is, 'We don't want you. We don't need you. We don't want you.'" "It was just tormenting for him." The two men then finally confronted each other, yelling until a group of officers separated them, he told his father. "One of his superiors came over and had Greg apologize to the guy," said the elder Buckley. The 21-year-old agreed and extended his hand, but the man refused. About a month later, Greg phoned his father again. "He told me if I have to stay here until November... I'm not going to come home." Greg also asked his father to prepare to tell his mother and his two younger brothers that he'd be killed. "I don't understand," his father said. "Out in the field?' "No, in our base," Greg replied. 4 NATO troops killed in 'insider' attack in Afghanistan . On August 10, 2012, Greg Buckley Jr. was gunned down by the very forces he had been training, just days after learning that he was to head home early. "It was only two days he had left there in Afghanistan," his father told CNN. The phenomenon is known as "green-on-blue," due to a color-coding system used by NATO. It has become disturbingly more frequent in Afghanistan, with more than 50 NATO troops killed this year by local forces, the first time that's happened in a single year in the U.S.-led war. Last year, 35 people died in such insider attacks, and even less the year before, according to NATO figures. The killings have prompted suspensions of training new recruits while eroding the trust between NATO and its Afghan allies. The gunman involved in Greg's death attacked from inside his outpost and killed two other fellow Marines, his dad said. But Greg Sr. said his son had informed his superior officers that "one day they are going turn around and turn those weapons on us." CNN cannot independently confirm that Greg informed superior officers. Calls and emails to NATO's International Security Assistance Force in Afghanistan were not immediately returned. More than a decade after the war began, the Buckley family is now struggling to cope with the loss of its eldest son. More than 2,000 other U.S. service members have been killed in Operation Enduring Freedom. "It's not really day-by-day," said Greg's mother, Marina Buckley. "It's more minute-by-minute." Back in Oceanside, the Buckley family on Friday attended the town's first home football game, where their fallen son had intended to watch his youngest brother play varsity for the first time. "Greg was supposed to be home for this game," said Justin, 17, who wore the number 30 on his back, Greg's old basketball number. "I would tell him I love him and I miss him." The senior running back, who donned a camouflage jersey along with his team, broke to the outside on Friday for a 25-yard score that helped cement the Sailors' improbable second-half comeback against top-ranked East Meadow. After crossing into the end zone, Justin raised his hand to salute -- honoring his fallen brother. NATO admits killing civilians in Afghan strike .

Input: Consider Input: HANOVER, Germany (CNN) -- Archaeologists have found more than 600 relics from a huge battle between a Roman army and Barbarians in the third century, long after historians believed Rome had given up control of northern Germany. Some of the artifacts are so well preserved that the scientists can already retrace some of the battle lines. "We have to write our history books new, because what we thought was that the activities of the Romans ended at nine or 10 (years) after Christ," said Lutz Stratmann, science minister for the German state of Lower Saxony. "Now we know that it must be 200 or 250 after that." For weeks, archeologist Petra Loenne and her team have been searching this area with metal detectors, pulling hundreds of ancient Roman weapons out of the ground. They paint a picture of a highly organized, technologically superior Roman army beset by Germanic tribes in a forest about 80 km (50 miles) south of the modern city of Hanover. The hillside battlefield was discovered by relic-hunters illegally searching for souvenirs of more recent wars near the town of Kalefeld-Oldenrode. One of them brought some of the items he found to Loenne, who works for the local government. The artifacts are so well preserved that the scientists can already retrace some of the battle lines.  Watch how the battlefield discovery could re-write history » . "We believe the Germans ambushed the Romans here, but the legions quickly fired back with catapults and archers -- and then it came to a massive man-on-man onslaught," Loenne said. The items unearthed so far include an axe, still sharp after nearly 1,800 years; horseshoes; shovels; spearheads; and dozens of arrowheads for a Scorpio, a cross between a catapult and a crossbow -- the ancient equivalent of artillery. "With a very high speed, on a very long distance -- about 300 meters -- you can hit targets precisely," said Henning Hassman, of Hanover's archeological institute. Researchers say the evidence suggests the tribesmen lured the Romans into the forest to keep them from making full use of those long-range weapons and draw them into hand-to-hand combat, outside of the formations the imperial troops had mastered. However, they believe the Romans ultimately prevailed. Other relics include coins depicting the late second-century Roman emperor Commodus, depicted in the Oscar-winning Hollywood epic "Gladiator" -- a film that opens with a scene of battle against a barbarian horde that scientists say appears to be largely accurate. And Loenne said her team may have only begun to scratch the surface of the forest. "We hope we might find fortifications and if we are lucky, maybe even battlefield graveyards," she said.

Input: Consider Input: Editor's note: Dr. Anthony S. Fauci is director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health. Dr. Anthony S. Fauci: Progress has been made in the fight against HIV/AIDS, but "our work is just beginning." (CNN) -- When we commemorated the first World AIDS Day on December 1, 1988, we had little to celebrate. The number of reported AIDS cases in the United States was nearing 80,000 and rising rapidly. Untold thousands more in this country were living with the human immunodeficiency virus, or HIV. Globally, AIDS cases already had been reported from more than 135 countries. An AIDS tsunami clearly was looming, but we had few defenses at our disposal. For those of us caring for people with AIDS, it was a dark time. We had just one anti-HIV medicine in our pharmacies, AZT, a drug that the virus rapidly defeated by mutating and developing resistance. Lacking other medicines to slow the relentless replication of HIV and its destruction of a person's immune system, we did our best to help our patients by managing to the extent possible their AIDS-related infections and complications. But the life span of most of the patients was measured in months. Two decades later, much has changed. An unprecedented research effort has led to more than two dozen anti-HIV drugs, more than for all other viral diseases combined. Taken in proper combinations, these medications have dramatically improved the prognosis for people living with HIV by increasing their life span by at least a decade and providing the possibility of a normal life span with continued therapy. Scientifically proven prevention approaches -- education and outreach to at-risk populations, voluntary HIV testing and counseling, condom distribution, prevention of HIV transmission from mother to baby, harm reduction approaches for drug abusers, mass-media campaigns and the screening of donated blood -- have been deployed with great success in the United States and many other countries. Innovative programs such as the President's Emergency Plan for AIDS Relief and the Global Fund for HIV/AIDS, Tuberculosis and Malaria, as well as the efforts of nongovernment organizations, have reached millions of people in low- and mid-income countries worldwide with HIV-related services, at a scale unimaginable a few years ago. And gradually -- but too slowly -- we have begun addressing AIDS-related stigma in this country and abroad. Much has been accomplished in the fight against HIV/AIDS from scientific, medical and public health standpoints. However, now is no time to rest on our accomplishments or our laurels. The statistics of the HIV/AIDS pandemic tell us that much more needs to be done. Around the world, a staggering 2.7 million people were infected in 2007 alone. Globally, 33 million people are living with HIV infection, most of them in the developing world. In the United States, more than 1 million people are living with HIV. And 56,000 more people are infected each year in the U.S., driving HIV prevalence rates in some of our communities to levels that rival those seen in sub-Saharan Africa. Gay and bisexual men, and African-Americans in general, are disproportionately affected. The true ground zero of the HIV epidemic in the United States is in those communities. What is the way forward? First, even in the face of a world economic crisis, the global community must scale up the delivery of proven HIV therapies and prevention services. In low- and middle-income countries, less than one-third of people in need of anti-HIV therapy are receiving it, and only one in five people at risk of HIV infection have access to prevention services. All around the world, access to HIV services -- and medical care in general -- remains a challenge in many poor communities. The global community must sustain our commitment to investing resources for medicines, clinics, as well as training and salaries for doctors, nurses and community health care workers to provide care for HIV/AIDS and other diseases in the settings where they occur. Here in the United States, more than one-fifth of people living with HIV are unaware of their infection and not receiving appropriate care for their own health or the prevention services that would help them avoid transmitting the virus to others. A frequent scenario is that people learn of their infection status only when they have advanced symptoms of HIV disease, when their health may by irreparably damaged. Now is the time for the medical community and policymakers to embrace U.S. guidelines for all Americans aged 13-64 to be voluntarily  tested in routine medical care. Barriers to implementation of HIV testing guidelines, such as state, local or agency regulations that conflict with the recommendations, variability in payment coverage for the test, and concerns about the stigma and discrimination that may accompany an HIV diagnosis, must be addressed. Meanwhile, we also must continue to invest in the next generation of treatment and prevention modalities. Encouragingly, new means of preventing HIV infection are emerging from well-designed and well-implemented clinical research trials. One exciting concept is pre-exposure prophylaxis or PrEP, giving preventive doses of anti-HIV drugs to individuals who are at an increased risk of HIV infection. This still-experimental strategy is based on the concept that if HIV replication can be inhibited immediately following exposure to the virus, permanent infection might be thwarted. Multiple clinical studies of PrEP are under way in the United States and in populations around the world. Ongoing research to develop microbicidal gels or creams to be applied before sex offer the hope of people being able to protect themselves from HIV infection in situations where saying no to sex or insisting on condom use is not an option. Finally, a preventive HIV vaccine remains the greatest hope for halting the relentless spread of HIV/AIDS. We must solve the mystery of how to prompt the human body to produce a protective immune response against HIV, which natural infection with the virus seems unable to do. Historically, it has taken decades to find effective vaccines to combat most infectious diseases. Researchers usually experienced numerous setbacks and disappointments before reaching success, yet they persevered. Finding a safe and effective HIV vaccine demands an equally intense resolve. On this World AIDS Day, we should be proud of the many scientific advances that have been made in the fight against HIV/AIDS. But it is hardly a time for self-congratulation. Rather, we must understand that our work is just beginning. Developing HIV interventions and delivering them to the people who need them will require scientific and public health vision, and dedication from all sectors of society, in good times and bad. The opinions expressed in this commentary are solely those of Dr. Anthony S. Fauci.
