In every war, they kill you in a new way.

During the Vietnam War, American military forces sprayed 20 million gallons of herbicides onto South Vietnam, eastern Laos, and parts of Cambodia. In effect, we caused Roundup to rain from the skies. For a decade.
Initially, the idea was to clear vegetation from the perimeters of U.S. bases.
Then the spraying was expanded to defoliate other areas of jungle, thus denying the enemy cover and concealment.
Then it was expanded again to destroy crops and deny the enemy food.
Destroying crops as a tactic of war is a violation of the 1925 Geneva Protocol. We did it anyway.
The defoliation program was known as Operation Ranch Hand. It lasted from 1962 until 1971, when the health effects of the herbicides — on our soldiers as well as their civilians — became too clear and alarming to ignore.
Ranch Hand used a variety of chemicals concoctions. They were shipped in drums marked with an identifying colored stripe.
The most widely-used mixture came in drums with an orange stripe. It became known as Agent Orange.
Today, Agent Orange is the term we use to refer to all of the chemicals mixtures sprayed at the time — Agents Orange, Pink, Green, Purple, Blue, and White.
To spray them, the Air Force used the Fairchild C-123 Provider, a sturdy and reliable military transport. When fitted with special aerial spraying equipment, these aircraft became the UC-123B, with a capacity of 1,000 gallons of herbicide.
In about five minutes, a typical plane could spray a swath of land 80 yards wide and 10 miles long. It applied the herbicide at the rate of about three gallons per acre. Missions usually consisted of three to five aircraft flying side by side.
Agent Orange was used because it was a powerful and effective herbicide. And, like Roundup, it was highly toxic. It posed a severe health risk to people, livestock, and wildlife. We used it anyway.
In the late 1960s, researchers came upon something unexpected. They discovered that small amounts of dioxins were being created, unintentionally, during the Agent Orange manufacturing process.
Dioxins, which are not found in nature, are some of the most toxic chemicals known. According to the EPA and the World Health Organization, there is no “safe” level of exposure.
Dioxins have been linked to cancer, birth defects, damage to the immune and hormonal systems, learning disabilities, diabetes, skin disorders, and more.
In 1970, a study specifically linked Agent Orange to birth defects in animals. By the end of that year, Operation Ranch Hand was terminated. All military use of the herbicides ended in 1971.
During the 1970s, veterans returning from Vietnam began to report skin rashes, cancers, psychological problems, and birth defects and handicaps in their children. Large numbers of veterans believed that exposure to Agent Orange was the cause.
In 1979, a large class-action lawsuit was filed against the herbicide manufacturers.
The primary manufacturers of Agent Orange, Monsanto and Dow Chemical, have always maintained that (1) their products caused no harm whatsoever and (2) they aren’t liable anyway.
It was clear that the chemical companies had the ability to drag out the litigation until the claimants were all dead. So, in 1984, the lawsuit was settled out of court.
It resulted in the Agent Orange Settlement Fund, which distributed roughly $200 million to 52,000 affected Vietnam veterans. The exposed veterans received an average of $3,800 each.
The impact of Agent Orange on millions of civilians in Southeast Asia was many times more horrific. The Vietnamese in particular suffered terribly. For 40 years, the country has dealt with disease and birth defects on a massive scale. They’re still working to reforest the land and restore wildlife populations.

When I went into the Air Force after college, the war in Vietnam was at its peak. The government shipped me off to Cannon AFB in Clovis, New Mexico, where I was assigned as Administrative Officer, Headquarters Squadron, 832nd Combat Support Group.
The Admin Officer is the assistant to the squadron commander. That’s the way young second lieutenants learn — working for a seasoned officer who knows what he’s doing.
And the system works pretty well. Spending every day around the commander and his key NCOs, I learned the art of running a military organization.
And I was luckier than most. My boss was the best military officer I ever knew, Major Lloyd Francis Walker.
Major Walker, a career man from Oregon, was a crackerjack officer. He was talented, dedicated, and a person of great integrity. He loved the Air Force. And he was a leader, not a whip-cracker.
Being the boss in any context, military or civilian, is tricky. A surprising number of bosses become bullies, because that’s the easy route. Your underlings can’t do much about it, except impotently despise you.
But that isn’t leadership. Leadership is when you earn the respect and good will of your people.
Major Walker was well-known and highly-regarded at Cannon. He also was a seasoned pilot, which is a good thing to be, career wise, in the Air Force.
Inevitably, the Major’s flight status meant a ticket to Vietnam.
In late 1966, he was transferred to the 12th Air Commando Squadron, Bien Hoa Air Base, as the pilot of a Fairchild UC-123B defoliation aircraft.
I don’t know if he welcomed the assignment, but he accepted it like a good soldier. I replaced him as Squadron Commander. His going-away party was a big deal at Cannon.
So was the news, just months later, of his death.
This item appeared in The Oregonian, the Portland newspaper, on February 1, 1967:
Oregon Major Dies in Battle
Salem (AP) — Air Force Maj. Lloyd F. Walker, 45, was shot down and killed on a flying mission over enemy territory in Vietnam, relatives here were notified Tuesday. A veteran of World War II and the Korean conflict, he was a pilot. Walker was born and reared at Mount Angel and attended Oregon State University. He leaves a widow, the former Betty Fay Guttenberg of Salem, and four children at home in Clovis, N.M.
Just recently, I found this information online on the P.O.W. Network:
Major Lloyd F. Walker was the pilot of a 12th Air Commando Squadron UC123B which was sent on a defoliation mission (Agent Orange) on 31 Jan 1967 over Laos. As the aircraft leveled off to start spraying, its propeller was struck by hostile fire. The aircraft crashed about 5 miles south-southwest of Sepone in Savannakhet Province, Laos. After an investigation, it was decided that Major Walker and his crew of 4 (which consisted of 3 captains and 1 Airman 1st class/flight mechanic) had died in the crash.
The day after the Major’s death, I wrote this entry in my diary:
Major Walker was killed yesterday in Vietnam.
We were notified this morning, and the whole base knew by noon. I was in Base Supply, and Sgt. Smith came in and told me. The Major was on his first combat mission as an A/C. It was only his 4th mission since he got there.
He and 1st Sgt. Stricklan were close. I can guess how Strick is taking this.
The Major planned to stay in Clovis after his retirement, which was just 10 months away. He told us this would be his 3rd and last war, and it was.
The young guys fight for the chance to go over there and win medals. I say let ’em. But wasn’t two wars enough? They should have let him sit this one out. But they didn’t, and he went, and it killed him. What an awful waste.

First Sgt. Stricklan, Major Walker, and the Airman of the Month, Cannon AFB, August 1966.
Major Walker was a genuinely good man. He was universally admired and respected. He was our own real-life Mister Roberts.
A few years ago, I went to Washington and took this photo of Panel 14E, Line 102 of the Vietnam Veterans Memorial.

The tragedy of war is that it uses man’s best to do man’s worst.

Rocky, moving post as always, what a waste. Strangely enough, I was at a party last night and we were discussing Monsanto and I shared this video with the folks involved in the discussion. I thought you might find it interesting as well.
Best,
God, that’s depressing. The cliche of the giant, evil corporation in the movies pales next to the real thing.
Rocky,
Found Mr Write’s Page earlier this week. Have enjoyed reading your thoughts and observations, your memories and recollections ~ seems you’ve had quite an adverture and enjoyed every minute of it.
Was especially appreciative of your memories of Cannon AFB.
As you noted, Major Walker was an exceptional leader. A fine example for all who served with him. Three times he gave his country his best. And then he gave the rest he had to offer, he gave his all.
Thanks for sharing,
Steve Nichols
Rocky,
I am a grandson of Major Walker. I am pleased that your account paints him in a light which is honorable of a man which I never had the pleasure of meeting. His memory and attributes affectionately live on within our family.
Trent Walker
I’m pleased to know that his family holds him in high regard. He well deserves it. Thanks for writing.
Rocky,
I am Major Walker’s oldest son, Terry. Trent is my oldest son. My Dad was truly a great man and always my hero. I remember the memorial service at Cannon. I have never seen so many grown men crying. I knew my Dad was well liked and admired, but never knew how much until that day. I am 63 now, but not a day goes by that I don’t miss him. Thanks so much for your post. Feel free to contact me if you would like to talk about him some more and learn what happened to our family after his death,
Terry Walker
Mr. Smith,
Thank you for this post! Major Walker was my grandfather. I never had the privilege of meeting him because his daughter (my mother) was only in high school at the time of his death. It seems odd to me that after all these years we (the family) are slowly getting information about what happen that tragic day. I never really knew anything about him other than he was an Air Force pilot who was killed in Vietnam. I’m very proud today knowing that my grandfather was a great leader and a loved man! Thank you so much for sharing your memories of my grandfather with us.
Larry Baca
Larry, I am so pleased to hear from you, as well as from other members of your family. Over the years, I have had very fond memories of your grandfather. He treated me and the other young men under his command with dignity and respect. Believe me, it isn’t always that way in the military. After his death, I served under two other commanders who were ill-suited for their jobs. They made Major Walker seem like an even better example of competent leadership.
If all my bosses had been like your grandfather, I might have made a career of the Air Force. But they weren’t, and I didn’t.
Later, when I was put in positions of leadership, I did my best to follow his example. I think — I hope — he would be proud.
Again, thank you for writing, and thank you for keeping the memory of your grandfather alive. He was an admirable man.
Rocky,
Thank you so much for your blog story about my Dad. I am Debbie, His only daughter. This happened so long ago that I thought I could just read it but no, I’m wiping away the tears as I write this. I only wish my Mom could have seen it but she died 11 years ago on December 1st. My mom never got over my Dad’s death. Our family does honor my Dad, he was a wonderful man. I only had him for 14 years so to this day I envy people who still have their dads. I’m so proud that my Dad had such an impact on you that you would write about him almost 50 years later.Thank you again and God bless you.
Debbie Snaith
Thank you, Debbie. I wrote the story to share it with my own family, having no idea yours would find it. Considering the power of the internet, I should have known better.
My dad flew combat missions in WWII and Korea, but he came home, and we had him until 2002. As a military family, we knew many who died young. Every day with him was a treasure, as you well know.
Hearing from you and your family has been very gratifying. It has reminded me again of how much all of us at Cannon AFB loved your dad.
Thanks again.
My name is Doug Walker and Major Walker was my Squadron Commander at Cannon in the middle 60’s. I thought so much of him that he is one of two people I honor each Memorial Day. I was only 18 when assigned to Clovis and he was everything I thought a career military person should be, the epitome of class and gentlemanly demeanor. I left Cannon in 1966 after being transferred to England. When I read of his death in The Stars And Stripes I was crushed. He was the first of my “friends” killed in the war. As you can tell from my writing he had a great impact on my life, and I will always remember him fondly. I know the entire family is very proud of him…as you should be. He was one of the good guys.
Thanks, Doug. If you’ve read the other comments, you know the Major’s family was, and is, very proud of him. He was indeed a good man and friend. Thanks for writing.
