The Special Forces soldiers were killed in an ambush while on a reconnaissance patrol in south Vietnam on April 17, 1969.
Thunderstorms in the area prevented rescue attempts, and Master Sgt. Charles Newton of Canadian, Texas; Sgt. 1st Class Douglas Dahill of Lima, Ohio; and Sgt. 1st Class Charles Prevedel of St. Louis, Mo., were labeled as missing in action for decades.
Between 1990 and 1993, the ambush site was excavated. Since then, government scientists have used circumstantial evidence and forensic tools, including dental comparisons and DNA, to identify the remains.
According to a report by the Fayetteville Observer, Wednesday's burial brings closure to the men's families who wondered for years what happened to them.
