5 Pieces Of Gear U.S. Soldiers Ditched In Combat (Vietnam War)

A soldier in Vietnam carried everything he owned on his back. 80 lb, sometimes more, in heat that could hit 100° with the humidity sitting on top of it like a wet blanket. So, when something in that load slowed him down, or worse, when it failed him in a firefight, he made a decision the army never planned for.

He threw it away. From a gas mask nobody wanted the riflemen dropped to pick up the enemies. These are five pieces of American gear that ended up abandoned in the jungle. And the reasons tell you almost everything about what that war was actually like. Here’s the thing you have to understand first. The United States walked into Vietnam built for a different fight.

The equipment, the doctrine, a lot of the training, all of it was shaped by the idea of a conventional war. Big armies, clear front lines, the kind of thing you’d expect on the plains of Europe against the Soviets. But Vietnam wasn’t like that. It was foot patrols through swamps and elephant grass. It was an enemy who hit and vanished.

It was heat, water, and rot working on a man’s gear 24 hours a day. So, the soldier in the field became his own quartermaster. He kept what worked, and he ditched what didn’t. Let’s start with the piece almost nobody fought to keep. Number five, the gas mask. Officially, it was the M-17 field protective mask. A heavy rubber mask with the filters built into the cheeks, carried in a canvas bag strapped to your leg.

It was designed to protect a soldier from chemical attack. And on paper, that’s a serious capability. There was just one problem. In the jungles of Vietnam, that capability was almost never needed. Think about it from the grunt’s point of view. He’s already carrying a rifle, ammunition, water, food, grenades, and a pack that’s crushing his shoulders.

And clipped to his leg is a bulky rubber mask for a threat that, on the average patrol, simply wasn’t there. The mask got in the way. The carrier slipped down when you waded through water, which soaked the mask and ruined it anyway. So, a lot of men did the math and quietly got rid of it. Now, it wasn’t completely useless, and this is the part that’s interesting.

The gas mask did have two real jobs in Vietnam. The first was tunnel and bunker clearing. When American troops used CS gas, basically military-grade tear gas, to flush enemy fighters out of underground tunnels, you wanted a mask on. The second job was grimmer. The mask was sometimes pulled out to block the smell during the awful work of counting bodies after a battle.

But, those were the exceptions. For day-to-day patrolling, the mask was dead weight, and the men knew it. And here’s how we know the soldiers were right. In 1966, the 1st Cavalry Division and the 1st Infantry Division didn’t just complain about the M-17. They formally requested a smaller, lighter mask, specifically because the standard one was too heavy and too bulky for the way they were fighting.

That request helped push the Army toward developing a lighter riot control mask later in the war. So, the gas mask is our gentlest example. Nobody died because they ditched it. But, it set the pattern for everything else on this list. If it didn’t earn its weight, it didn’t survive contact with reality. This next one was a much harder call.

Because ditching it meant giving up protection. Number four, the flak jacket. This one is more complicated, and the way different troops handled it tells you a lot. The flak jacket was body armor, but you have to be precise about what it actually did. It was designed to stop fragments. Shrapnel from grenades, mortars, and artillery.

It was never built to stop a rifle bullet. The army had a couple of versions, the M-1952, and later the M-69. The Marines had their own, the M-1955, with rigid fiberglass plates inside. They all weighed somewhere around 8 to 10 lb. And in the heat of Vietnam, those pounds came with a hidden cost. A flak jacket traps heat. It traps sweat.

On a long foot patrol in tropical humidity, that turns into a real danger. Men dropping from heat exhaustion. And remember, the jacket wouldn’t stop an enemy AK-47 round anyway. So, a lot of soldiers, especially army infantry, out humping the bush, made a brutal trade. They took the jacket off and carried it, or left it behind entirely, betting that mobility and not collapsing from the heat mattered more than fragment protection.

But, and this is the key contrast, it depended heavily on which branch you were in and what kind of fighting you were doing. The Marines were generally ordered to wear their flak jackets. And in the kind of fighting Marines often found themselves in, dug-in positions under constant artillery and mortar fire at places like Khe San and Con Thien, that armor genuinely saved lives.

 When the threat is flying shrapnel and you’re not running anywhere, a flak jacket is exactly what you want. So, the same piece of gear that an Army patrol dumped in the jungle was the gear a Marine clung to in a bunker. Both were right for their war. The military knew the armor wasn’t good enough. Late in the war, they tested a heavier vest with ceramic plates that could actually stop rifle rounds.

 But, it weighed around 20 lb and cost a fortune compared to the cloth vests. And the program was canceled in 1970. Real bullet-stopping body armor for the average infantryman wouldn’t arrive for decades. So, the flak jacket was a compromise nobody loved. And that brings us to the middle of our list and the single most infamous piece of gear in the entire war.

The one men didn’t just leave behind. They threw it down and picked up the enemies. Number three. The M-16. When American troops first got the M-16, it must have felt like the future. It was light, far lighter than the heavy wood and steel M-14 it replaced. It fired a small fast round, and it could go full automatic.

 For close jungle fighting, it looked like the perfect weapon. And then men started dying with it jammed in their hands. In the spring of 1967, near Khe San, Marines assaulted dug-in North Vietnamese positions on a hill called 881 South. It was part of what’s remembered as the hill fights. And in the middle of the assault, their brand new M-16s began to jam.

Not occasionally, constantly. The most common failure was the worst kind. A spent cartridge case would get stuck in the chamber after firing. To clear it, you had to ram a cleaning rod down the barrel to knock the jammed case out, all while under fire. A rifle that should fire 30 rounds had become a single shot in the worst possible place to find out.

The accounts from that fight are haunting. Marines reported finding their own dead next to M-16s that had been taken apart. Men killed while desperately trying to fix a jam. Some grabbed AK-47s off dead North Vietnamese soldiers because the enemy’s rifle worked when theirs wouldn’t. Now, here’s where we place a voice that was actually there.

>> A C-130 crashed and burned. Uh I’ve got the names from the wall. Uh uh of probably five of those crewmen died there. Only one uh say of six crewmen survived and that was the captain, the commander of the craft cuz Khe Sanh was a major uh resupply issue even when I was there. Then the road was cut.

 Shortly after I got there, the uh the highway where convoys would have come in, uh the uh North Vietnamese had basically taken over and cut that road so you couldn’t come in anymore through So, all of the supply and evac was done through air. And I can remember them trying various I guess they were testing.

 I I remember I first uh uh was introduced or at least became aware of of of uh the low altitude parachute ejection where they come across the runway, you know, that high and basically uh use a shoot to jerk the uh cargo out while the plane never stopped and kept going. So, what actually went wrong with the M-16? Because this is the part most people get wrong.

The rifle itself was not the problem. Here’s the proof. Back in 1965 in the Ia Drang Valley, early M-16s worked just fine. The special forces who first received the rifle loved it. The weapon was sound. What killed those Marines was a chain of decisions made far from the battlefield. The army changed the gunpowder in the ammunition to a type that burned dirtier and fouled the rifle faster.

They decided not to chrome line the chamber, which in Vietnam’s humidity meant it corroded and pitted, making jams worse. And then, incredibly, the rifles were handed out with the message that they were practically self-cleaning. Men were issued no cleaning kits and given little instruction. A weapon that desperately needed cleaning was sold to the troops as a weapon that didn’t.

The scandal got so loud that Congress investigated. On October 19th, 1967, a House subcommittee led by Congressman Richard Ichord released its report. The findings were damning. The investigators concluded that the army’s handling of the ammunition issue, in their words, bordered on criminal negligence. The fixes came after that.

 The improved M-16A1 got a chrome-plated chamber, a forward assist, a new buffer to slow it down, and yes, even a famous comic book-style manual to teach men how to maintain it. The rifle eventually became one of the longest-serving in American history. But that’s cold comfort for the men on Hill 881. The most advanced rifle of its day was failing in their hands, and so some of them did the only thing that made sense.

They ditched it for the enemies. After the weight of that, our next one is almost a relief. It’s strange. It’s a little funny. And it’s one of the few items on this list backed up by an actual military regulation. Number two, their underwear. I know how that sounds. But stay with me because this one is real.

 And it points to one of the biggest hidden enemies of the entire war. Not bullets, skin disease. In the wet lowlands and the rice paddies, especially down in the Mekong Delta, soldiers were soaked for days at a time. Constant water, heat, and no way to dry out. And the result was an epidemic of what the troops called jungle rot. Fungal infections, bacterial infections, immersion foot, the skin literally breaking down.

This wasn’t a minor annoyance. According to the US Army’s own medical history, after just a few days slogging through flooded paddies, as many as half the men in a unit could come down with immersion injuries. The Army’s official medical record notes one stark example from 1968. The 9th Infantry Division reported that after 5 days in the Delta, a battalion’s strength was cut by as much as a third by skin disease alone.

So, what does that have to do with underwear? The doctors figured out that the core problem was wet. Occlusive clothing pressed against the skin, trapping moisture against the body in exactly the places that rotted first. The groin, the feet. And so, the Army did something genuinely unusual. In January 1968, US Army Vietnam issued a regulation that put it in writing.

Troops, it said, should be discouraged from wearing underclothes while operating in the field because underwear reduced ventilation of the skin. Not banned, discouraged. But it was official, on paper, with a regulation number. Now, let me kill a myth right here, because the internet loves to exaggerate this one.

The socks part is backwards. The official advice on socks was the opposite. Change into dry socks every day and air your feet out whenever you could. Dry socks were a weapon against jungle rot, not a casualty of it. And the phrase going commando was not born in Vietnam, despite what you’ll read in a hundred comment sections.

 So, the truth is more interesting than the myth. Men shed their underwear on the advice of army doctors to keep their own bodies from falling apart in the wet. It’s the one item on this list they ditched on doctor’s orders, which brings us to our final piece. And it ties this whole list together. Number one, the bayonet. For centuries, the bayonet was the soul of the infantry.

The final argument. Fix bayonets and charge. So, you’d think it would matter in Vietnam. It mostly didn’t. Ask the men who carried one, and you hear the same thing again and again. The bayonet in Vietnam was a tool, not a weapon. They used it to cut vines and brush, to dig, to pry open a can of C rations. As an actual fighting blade in the era of fast, lightweight automatic rifles, it almost never came off the belt for its intended purpose.

Some mechanized units weren’t even issued them or turned them in as the war went on. But the bayonet is really standing in for something bigger here. Because the real story of this whole list isn’t five separate decisions. It’s one decision made over and over by every man who ever shouldered a pack in that country.

The infantrymen was carrying 80 lb, sometimes 100 for the machine gunners and radio operators, through terrain designed to break a man down. And the field manuals themselves warned that an overloaded soldier becomes, in the cold phrase of the day, comfortably dead. So, men became ruthless about weight.

The gas mask went. The flak jacket came off. The sleeping bag, useless in the heat, got left behind. The bayonet stayed on the belt, but rarely did its job. Even the hated C rations got triaged. The dreaded ham and lima beans famously left for somebody else, or buried so the enemy couldn’t eat them.

Every one of these five choices came from the same place. The men in the field knew something the planners back home didn’t. In that war, survival wasn’t about carrying everything. It was about carrying only what would keep you alive. So, there they are. Five pieces of American gear that ended up dumped, stripped off, or quietly abandoned in the jungles of Vietnam.

 The gas mask nobody needed. The flak jacket that couldn’t follow you into the heat. The rifle that failed when it mattered most. The underwear the doctors told men to lose. And the bayonet that became a can opener. Each one is a small window into a bigger truth. The gap between the war the United States planned for, and the war its soldiers actually had to fight.
