HAT YAO, Thailand — After training with Okinawa-based Marines and Navy corpsmen, Thai servicemembers hit the beach and sent dozens of civilians to a “safe haven” during a noncombatant evacuation exercise Tuesday.

During the three days of training and rehearsal as part of Cobra Gold 2005, the 28 Marines and three sailors focused on four areas with the Thais: security, the U.S. military’s satellite-based noncombatant tracking system, transport and urgent medical care.

A group of about 40 Thais played noncombatant roles for the exercise.

The first few to receive attention were the injured, one badly enough to be taken on a stretcher into a medical tent.

While he was treated, his passport information was entered into the “Neo” tracking system, enabling a distant command post to observe the processing.

Even in the chaos of treating his serious injury, a bar code bracelet printed from the tracking system was slipped around his arm.

“One of the things they’ve learned … is accountability of personnel,” said Maj. Kevin Collins, operations officer with Combat Logistics Regiment 7. “Who goes where is very important in an operation like this.”

The badly injured patient soon was evacuated by a helicopter, which landed about 100 yards from the medical tent.

The rest of the noncombatants were patted down and searched by security officers. A few appeared drunk and began swatting at the officers. Such “belligerents” had their passports scanned by the tracking system but were held under guard.

With all of the evacuees processed and awaiting rescue, a gunmetal-gray landing craft appeared from the sea. Armed Thai Marines formed barriers parallel to where the ship landed, just a few feet from shore. The evacuees boarded the vessel and were whisked to safety.

This was the first time the Thais had worked with the computer-based tracking system, which the United States has used since 2000 to evacuate personnel from danger zones and disasters.

“You can see a progression of confidence on how well both us and the Thais are working on this,” said Col. Doavin Lewis, commanding officer of Combat Logistics Regiment 7 from Camp Foster, Okinawa.

Royal Marine Petty Officer 1st Class Preecha Sudsuwan said he never before had trained in a live evacuation simulation.

“I like that the exercise is so real,” Sudsuwan said through a translator. “You understand how it actually is.”

The training does much to prepare the servicemembers for any future disasters, Sudsuwan said.
