SYNOPSIS: The 3rd Squadron, 17th Cavalry was part of the 12th Aviation Group
during its service in Vietnam. It was responsible for air cavalry support in
the western part of III Corps Tactical Zone. In late 1970 it was placed
under the operational control of the 1st Cavalry Division to form a highly
successful ad hoc air cavalry brigade.

On July 24, 1971, WO1 Timothy G. Wiltrout, pilot; Sgt. Gregory A. Antunano,
observer; and SP4 Randall D. Dalton, door gunner; were crew members on an
OH6A "Loach" observation helicopter (serial #17-257) which was shot down by
enemy fire while on a reconnaissance mission in Cambodia. The aircraft went
down about 5 miles inside Cambodia, in Kracheh Province, just a few miles
southeast of the city of Snuol.

When rescuers arrived at the crash site, they found the pilot outside the
downed aircraft. He suffered a broken leg in the incident, but was otherwise
unhurt. The other two crew members were still strapped in their seats inside
the wreckage. Both were taken out of the helicopter and at that time, SP4
Dalton was still alive. Sgt. Antunano was believed to be dead.

A short time later, SP4 Dalton stopped breathing. Efforts to revive him were
unsuccessful. The medic checked both Dalton and Antunano several times, and
told other rescuers that they were dead.

As enemy soldiers began moving into the area, search and rescue aircraft
evacuated the rescue team and Wiltrout, the pilot. Because of enemy
presence, no attempt was made to extract the two bodies. They were left
lying near the downed helicopter.

The following day, several SAR aircraft returned to the location in an
attempt to recover Antunano and Dalton, but noted that the aircraft had been
stripped and moved several feet. Personal effects of the crew, such as their
helmets, weapons and the aircraft radio had also been removed. Sgt. Antunano
and SP4 Dalton's bodies were gone. A search of the area from the air did not
reveal fresh graves or any sign of the two men.

Antunano and Dalton's bodies were never found. They are listed with honor
among the missing because their remains are still on enemy soil. For other
missing Americans, simple resolution is not possible. Some were in radio
contact with would-be rescuers - some simply did not return from missions.
Others were known prisoners who disappeared from prison systems and were not
released at the end of the war.

"Several million documents" and 250,000 interviews have convinced many
officials that Americans were left behind in Vietnam and that some remain
alive today. Some number those alive in the hundreds. While Dalton and
Antunano may not be among them, if there is even one American left alive, we
must do everything possible to bring him home.

Before his loss, Antunano was awarded The DFC (Distinguished Flying Cross),
Bronze Star Medal w/ Oak Leaf Cluster, Army Commendation Medal
w/ "V" devise for Heroism w/ 2 Oak Leaf Clusters, Purple Heart, Good
Conduct Medal, NDSM (National Defense Service Medal), Armed Forces
Expeditionary Medal (Korea), Vietnam Service Medal, Vietnam Campaign Medal,
CIB (Combat Infantry Badge), Aircraft Crewman Badge and the Expert Badge w/

Posthumously Awarded: DFC w Oak Leaf Cluster, Air Medal w/ 2nd thru 7th
Award, and the Purple Heart w/ Oak Leaf Cluster.

On July 24, 1971, an OH-6A Cayuse (tail number 17257) with a crew of a three was shot down by enemy ground fire while conducting a reconnaissance mission over Cambodia. It crashed in the vicinity of (GC) XU 730 333. When search personnel arrived at the crash site, they found the pilot and door gunner were still alive but the observer had died in the crash. However, the door gunner died on the scene shortly after the rescuers arrived. Enemy forces then began moving into the area, and the rescuers were forced to withdraw without the remains of the door gunner and observer. The remains of the door gunner were subsequently recovered, but the observer is still unaccounted for.

Sergeant Gregory Alfred Antunano entered the U.S. Army from California and served with Troop A, 3rd Squadron, 17th Cavalry Regiment. He was the observer on this Cayuse at the time of its loss, and rescuers determined that he was already dead when they reached the crash site. His body had to be left behind when enemy troops arrived, and was not recovered. He remains unaccounted for. Today, Sergeant Antunano is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific.
