Why SEALS Wore Pantyhose and Levi’s Jeans in Vietnam? D

Before you go in tonight, you do something that would get you laughed out of any stateside garrison. You pull on women’s pantyhose. Over that, a pair of Levi’s 501 jeans. On your wrist, a Rolex you buy yourself at the PX for $150. And on the muzzle of your M-16, a condom. You are a Navy SEAL.

You are about to step into the Rung Sat Special Zone, a 485 square mile maze of tidal mangrove swamp southeast of Saigon that the US military handed to its naval forces because no one else knew what to do with it. The name means salty forest in Vietnamese. Americans translated it as forest of assassins.

Both are accurate. The official gear is killing you, not the enemy, the gear. And in a few hours, when you step off dry ground into chest-deep mud in the dark with leeches moving toward you and a rifle that may or may not function when you need it, you will understand exactly why you chose a dollar’s worth of nylon over everything the United States Army procurement system could provide.

But there is one more thing in your kit tonight that the Army cannot know about. Something that would get you shot as a spy if the wrong people found out. We will get to that. Start with what the Rung Sat actually was because nothing else makes sense without it. The Delta was not a war zone. It was an environment.

Daytime temperatures in the 90s, humidity that turned cotton into a bacterial colony, tidal rivers that rose and fell twice daily, mangrove roots that grabbed your boots, mud that took them. SEAL Kirby Harrell, who ran point for Foxtrot Platoon in 1970, described ambush positions in swamp water that reached his chest.

5 km of that mud per operation, minimum. And before you ever met the enemy, the environment had already begun its work on you. The standard issue jungle fatigue had cargo pockets on both thighs. In a dry environment, they were useful. In the Delta, they were anchors. Every time you crossed a waterway, which was constant, those pockets filled with mud and water.

Not the kind that drains, the kind that sits. Harrell documented this precisely. The mud didn’t cling to Levi’s like it did to the camo pants and there were no large side pockets on the jeans like there were on the camo pants that would fill with water when you came out of a river or canals. The weight was not abstract.

In an ambush, a 1-second delay in movement caused by water-logged leg pockets was the kind of thing that showed up in a casualty report rather than an after action. Speed in the Delta was survival. The cargo pockets stole speed. The solution spread not through official channels but through word of mouth between platoons rotating through the Rung Sat.

Levi’s 501 and 505, those specific models. The geometry was exact. Close-fitting, small, flat pockets that did not balloon underwater. Heavy denim that shed water instead of holding a tight enough weave to resist the elephant grass that shredded standard fabric. Gene Wentz documented his team’s loadout in Men in Green Faces.

Levi’s 501s or cammie bottoms. Roger Hayden, a Vietnam era SEAL, described what the result looked like from the outside. Coral boots, Levi’s jeans, Rolex on the wrist, you could identify a SEAL at a glance. The civilian gear had become the elite uniform. The army’s response to this field solution was no response. There was no official modification.

The Levi’s never appeared in a procurement document. They spread the way the best solutions in Vietnam spread. One veteran telling the next man what kept him alive. The pantyhose addressed a different problem in the same swamp. Tropical leeches moved purposefully toward warm bodies. They found the gap at the boot cuff, crawled through the weave of standard fabric, and attached in locations that required a degree of self-examination incompatible with tactical movement.

SEAL Jim Berta, the leeches could crawl up the legs. Horell, leeches would always tie to you. The standard jungle fatigue gave them every gap they needed. Loose weave, open cuffs, waistbands that didn’t seal. Horell’s platoon found the fix through the girlfriends by mail method. That’s where we started having our girlfriend send us pantyhose.

We could put pantyhose on and the leeches couldn’t bite through them. The mechanism is material geometry. Nylon mesh is too tight for leech mouth parts to penetrate. The smooth surface gives them no grip to crawl. And pantyhose are engineered to conform to the leg without gaps, eliminating the entry points that standard pants provided.

The operators who wore pantyhose under their Levi’s moved to the same swamps that had been making the standard issue approach a medical maintenance problem. They came out clean. That combination, civilian jeans and women’s hosiery, is funny for exactly as long as it takes you to understand what it solved.

After that, it’s just engineering. But the leeches and the mud were what you could feel. What was happening to the men who stayed wet for 72 hours was harder to see coming. Until entire units stopped being able to walk, the army’s own documents on immersion foot read like an indictment.

A ninth infantry division memo dated October 28th, 1968, a primary army document, stated that diseases of the foot may affect 35 to 50% of the combat strength of an infantry unit after 72 hours of exposure to rice paddies and swamps. An army physician documenting his work with the second brigade, first infantry division, recorded that before his intervention a combat unit could experience 70 to 75% loss of personnel due entirely to inflammatory skin diseases of feet that have been continuously wet more than 72 hours. The AMEDD’s own historical record states, “Tropical immersion foot often accounted for more time lost from combat duty than all other medical causes combined.” Cotton socks held water against skin. The army knew this. USARV regulation 4029, issued January 10th, 1968, tried to address the problem with a policy that discouraged but did not prohibit underwear on operations. Because underwear reduced ventilation of the

skin, the physician’s solution for the second brigade was 5,000 pairs of rubber shower thongs and a directive to get feet dry every 48 hours. Meanwhile, the informal network was already running. soldiers wrote home for wool socks, nylon socks, anything that wicked moisture instead of holding it.

The requests arrived in care packages alongside the food and the letters, an informal supply chain moving faster than any procurement cycle. The army never officially solved this for the men in the field. The men in the field solved it without the army. Going commando arrived in American slang during and after the Vietnam War from exactly where the name suggests.

Cotton underwear in sustained heat and humidity was a bacterial incubation chamber. Fungal infections documented in AMED records as among the most common and troublesome of all dermatologic conditions degraded operational effectiveness the same way immersion foot did, just more privately. The documented solution, no underwear or nylon which dried almost instantly and generated no friction in sustained movement.

The army’s official guidance on underwear was to discourage it during operations. The soldiers were already ahead of that guidance. What you carried on your feet and what you wore on your body, the army at least had opinions about. What was happening to your rifle was a different category of failure entirely because the army had opinions about that, too, and people were dying in the gap between those opinions and the fix.

The M-16 that American troops carried into Vietnam in 1965 and 1966 had a specific failure mode that is now well documented. The army had substituted a ball propellant Olin Mathieson WCC 846 for the original powder specified in the rifle’s design. The substitution raised the cyclic rate and increased fouling. The chamber was not chrome plated.

In the delta’s humidity and mud, spent cases corroded and stuck in the chamber after firing. Clearing a stuck case required a cleaning rod ram down the muzzle while still in contact with the enemy. The rifle had been issued without cleaning kits. In the spring of 1967, a Marine wrote a letter home from the hill fights near Khe San.

Time magazine published it. We left with 250 men in our company and came back with 107. We We with 72 men in our platoon and came back with 19. You know what killed most of us? Our own rifle. Practically every one of our dead was found with his rifle torn down next to him where he had been trying to fix it.

Marine losses at the hill fights were between 155 and 168 killed in action depending on the source. The Wikipedia figure is 155. The official USMC historical record gives 168. No official figure attributes a specific number of those deaths to the jamming problem. What exists is the testimony soldiers found dead next to disassembled rifles, cleaning rods in the barrel, dying trying to clear a jam.

On May 3rd, 1967, the House Armed Services Committee established the Special Subcommittee on the M-16 Rifle Program. Chairman, Representative Richard Ichord of Missouri. 10 days of hearings across May, June, July, and August 1967. The report issued October 19th, 1967 identified the Army Ordnance Department’s powder substitution as a primary cause.

The report used the word negligence. The M-16A1 was the fix. Chrome-plated chamber and bore, buffer modification, cleaning kits, a comic book maintenance manual. It began reaching troops in 1967. The hearings that proved the original rifle was killing men were held in the same year the fix arrived. The men in the field were not waiting for procurement.

Before the chrome chamber, before the cleaning kits, they had already found a solution that cost nothing and weighed nothing. An unlubricated condom stretched over the M-16 muzzle kept the bore sealed against water and mud during movement through swamps and canal crossings. The small bore of the 5.

56 mm round holds water by capillary action. Surface tension keeps it in where a larger caliber would drain. A water-obstructed bore can burst when fired. The condom solved this. When contact came, the operator fired through the latex without removing it. The round went through, the barrel was clean, non-lubricated because lubricant in the chamber was not an improvement on the problem.

The Army did not issue condoms for muzzle protection. The men requested them from medical supply and care packages. The solution spread through the same informal network as the socks and the Levi’s. No procurement document, no field modification advisory, word of mouth. Now you understand why you’re wearing pantyhose and jeans.

You understand why the condom is on your rifle. You understand that the army documented these problems, held hearings about some of them, and fixed what it fixed on a timeline that did not wait for the men who needed it sooner. What comes next is something the army cannot know about at all. You are in the kit bag now.

You pull out the NVA fatigues. MACV SOG ran cross-border reconnaissance teams into Laos and Cambodia, denied territory. Teams of six to 12 men, typically three Americans and indigenous Montagnard fighters, moving through triple canopy jungle where the nearest friendly force was hours away by helicopter.

When contact happened, it happened at 8 to 10 m, sometimes less. Triple canopy absorbs light and sound and distance. Two patrols can be 30 ft apart and hear nothing until they’re on each other. At that range, visual recognition precedes trigger pull by a fraction of a second. That fraction is the entire margin between who fires first and who doesn’t fire at all.

SOG point men began wearing captured NVA fatigues and carrying captured AK-47s. Not for infiltration, not as disguise in the traditional sense. For one thing only, the moment of contact. John Plaster documented this in Secret Commandos with page level specificity. Page 36 describes an eight-person recon team whose point element wore NVA uniform and carried an AK.

Page 182 outlines the practice as standard for the point position. John Stryker Meyer, whose recon team carried a point man named Sun in NVA uniform with an AK, documented the tactical logic across two books. The silhouette registers as friendly, the weapon sounds friendly, and for the length of a single breath, the enemy patrol does not immediately engage.

SOG veterans describe that moment as a hesitation, not measured, not timed. A hesitation long enough. The AK-47 7.62 mm round has a different acoustic signature than the M-16’s 5.56. Slower, heavier, the sound of a weapon the enemy knows. When the point man fires, it sounds like their round. The hesitation extends.

In the moment after you pull the trigger, the men behind you open fire. The patrol that came around that tree line at 8 m had a fraction of a second where your uniform told them you were theirs. It was enough. You are wearing this uniform knowing what happens if you are captured in it. The day over day law of war manual is precise on the point.

Fighting in an enemy uniform is not a lawful ruse. It is improper use of enemy insignia. If captured, a soldier wearing enemy uniform during a firefight has no protection under the laws of war. He can be shot as a spy. Plaster documented the operational reality plainly. Not one of McAfee’s SOG’s 57 missing Green Berets, nearly all of them undisguised when captured, came back alive.

The legal risk was theoretical. The practical risk was already total. Travis Mills, an instructor at the McAfee SOG 1-0 school, documented another problem the uniform created. When a door gunner on an extraction helicopter sees a man in NVA fatigues running out of the tree line toward his aircraft, he does not hesitate either.

Mills recorded in The Sentinel in 2018, “We did have a team member shot by a jumpy door gunner. Fortunately, the team member survived. The solution was colored bandannas. The team color changed per operation, communicated to extraction aircraft, so that anyone in the landing zone without the right color was fair game.

” No official document authorized the enemy uniform practice. It spread through SOG the same way the Levi’s spread through SEAL platoons. The men who needed it did it. The institution looked the other way. Every item in this kit connects to the same institutional fact. The cargo pocket problem was documented before the Levi’s solution spread.

The immersion foot rates 35 to 50% of units after 72 hours appear in Army medical records dated 1968. The M-16 failure mode was documented in field reports before a Marine wrote home from Khe San about the men who died trying to clear the jam. The congressional hearing that proved it happened in the same year the fix arrived.

The men in the Delta and the men running the fence of the Laos were not more creative than the Army. They were faster. They were solving problems on the timeline that applied to them, which was the timeline of their own survival using whatever the base exchange had, whatever their girlfriends could mail, whatever the enemy had left behind.

The solutions moved through informal networks because the formal ones were too slow. The pantyhose kept the leeches off, the Levi’s drained instead of filling with mud, the condom kept the barrel clean enough to fire when the moment came. The uniform bought the hesitation. The soldiers who figured this out never filed a report about most of it.

It spread the way everything in Vietnam spread, one veteran telling the next man what kept him alive.
