By Sound Alone

A Medevac in Vietnam.

Two o'clock in the morning, a few days before Christmas 1969. The request reached our Air Support Radar Team at An Hoa, Vietnam.

A Marine unit was pinned beneath triple-canopy jungle. Three men wounded. Darkness and weather ruled out a visual approach. Even if a helicopter found the unit, the crew couldn't see the ground through the canopy.

I was a young Marine officer, second in command of the ASRT and, at 23, the second-oldest in the unit. Most of the Marines around me were teenagers, or barely past it. We didn't think about our age. We had training, responsibilities, a mission.

Our equipment was the AN/TPQ-10, a radar and analog computer built to direct bombing runs when pilots couldn't see their targets. We could find an aircraft on radar, fix its position, and issue headings that put it exactly where it needed to be.

That night, we used it to save lives instead of end them. Instead of guiding a bomb to a target, we'd guide a helicopter to pick up three wounded Marines.

Only two of us at An Hoa were qualified controllers: our CO and me. My training had been a month on-the-job training at Da Nang. After that, I was expected to do the job. Nobody treated it as extraordinary. That's just how things were done.

The Medevac helicopter was a Huey. I don't remember the call sign. I just remember the challenge of controlling it.

Dead of night and fully socked in. The pilot couldn't anything. Nor could we. In our van, the jungle was coordinates and calculations. The Huey was a blip on a scope. The Marines on the ground were grid coordinates relayed over the radio.

Our job was to close that gap. I gave a heading. The pilot read it back. We watched the aircraft answer on the scope.

There was no room for error. On a bombing run, a mistake put ordnance in the wrong place. On this run, a mistake would send the Huey past the unit, or crash it into terrain nobody could see.

No ground beacon. Just corrections, over and over, as the return crept across the scope.

The young Marines running the equipment around me didn't get careless because it was two in the morning. Nobody could afford to.

We guided the Huey to a point in the sky. The men on the ground guided it the rest of the way by sound alone. The pilot held position while a line disappeared into the trees below them.

Three wounded Marines came out because of it.

We didn't celebrate. A few relieved words, maybe. Then back to work. Another mission was already coming in.

I didn't think about the ages of the Marines around me.

The Marine Corps handed us complicated equipment and expected us to master it. It put aircraft under our control and expected accuracy. It made us responsible for the lives of pilots, aircrews, and Marines on the ground.

We understood what was expected. We did it.

I've only recently understood what that night says about youth. When we hesitate to hand young people real responsibility, we assume they aren't ready. We protect them from hard decisions, then wonder why they struggle to make them.

In December 1969, in a radar van at An Hoa, most of the Marines running that mission were teenagers. They operated radar and and maintained equipment in a combat zone. They calculated courses, talked to aircraft, and helped put a helicopter above three wounded men hidden under triple-canopy jungle in the dead of night under zer0-zer0 conditions.

They were young. They were also remarkably capable.

We trusted them because they were worthy of that trust.

And they proved it.
