The remains of four U.S. servicemen missing in action from the Vietnam War have been identified and will be returned to their families for burial with full military honors, the Department of Defense announced today.

They are Maj. Barclay B. Young, of Hartford, Conn.; and Senior Master Sgt. James K. Caniford, of Brunswick, Md. The names of the two others are being withheld at the request of their families. All men were U.S. Air Force. Caniford will be buried Wednesday in Arlington National Cemetery near Washington, D.C., and Young's burial date is being set by his family.

Remains that could not be individually identified are included in a group which will be buried together in Arlington, the military said. Among the group remains is Air Force Lt. Col. Henry P. Brauner of Franklin Park, N.J., whose identification tag was recovered at the crash site.

On March 29, 1972, 14 men were aboard an AC-130A Spectre gunship that took off from Ubon Royal Thai Air Force Base, Thailand, on an armed reconnaissance mission over southern Laos. The aircraft was struck by an enemy surface-to-air missile and crashed. Search and rescue efforts were stop

In 1986, joint U.S.- Lao People's Democratic Republic teams, lead by the Joint POW/MIA Accounting Command at Hickam Air Force Base surveyed and excavated the crash site in Savannakhet Province, Laos. The team recovered human remains and other evidence including two identification tags, life support items and aircraft wreckage. From 1986 to 1988, the remains were identified as those of nine men from this crew.

Between 2005 and 2006, joint teams resurveyed the crash site and excavated it twice. The teams found more human remains, personal effects and crew-related equipment. As a result, JPAC identified Young, Caniford and the other crewmen using forensic identification tools, circumstantial evidence, mitochondrial DNA and dental comparisons.
