5 ways US military combat uniforms have changed since Vietnam
Sponsored by PROPPER
When you’re asked what’s the most important tool for any U.S. service member who’s facing down a bad guy in battle, the most obvious response is his or her weapon.
When it comes down to it and the shots are flying, it’s the rifle or handgun that can make the difference between victory and defeat. But there’s a lot more to it than that, and oftentimes it’s what the trooper is actually wearing that can determine whether the bullets start flying in the first place.
Military uniform designers and suppliers over the last half century have been developing new ways to help soldiers, sailors, airmen and Marines avoid fights if they want to and to survive them when things go loud. From things as simple as pocket placement and camouflage, to fabrics that won’t burn or show up in night vision goggles, the folks who build combat uniforms for America’s military have taken the best of material science and matched it with the conditions and operations troops are facing in increasingly complex and austere combat environments.
While the “modern” battle uniform traces much of its lineage to the Vietnam War, a lot has changed in the 50 years since that utilitarian design changed the course of what U.S. service members wear when they fight.
1. Combat uniform pockets
It was really the Korean war that introduced the pant-leg cargo pockets we all know today, according to an official Army history. But combat uniforms issued to troops in Vietnam took those to another level.
With bellowed pleats and secure flaps, there were few items the side cargo pocket couldn’t handle. Vietnam-era combat blouses also used an innovative angled chest pocket design that made it easier to reach items in the heat of battle.
In the 1980s, the U.S. military ditched the angled chest pockets for vertical ones, mostly for appearance, and the combat trousers maintained their six-pocket design until the 2000s.
But when America went to war after the Sept. 11 terror attacks, pocket placement and design took a quantum leap. Way more “utilitarian” than combat threads of Vietnam and the Cold War, the new battle rigs are like night and day — with everything from pen pockets near the wrist of a combat blouse, to ankle pockets on the trousers to bellowed shoulder pockets.
Interestingly, it was special operations troops that developed the shoulder pocket later adopted by both the Marine Corps and Army for their combat uniforms. During the opening days of the Global War on Terror, spec ops troops cut cargo pockets off their extra trousers and sewed them onto the arms of their combat jackets, giving them extra storage within an arm’s reach.
Modern combat uniforms now also incorporate internal pockets for knee pads and elbow pads, so when a trooper has to take a knee or go prone in a hurry, he’s not banging his joints on the dirt.
2. Combat uniform material
By Vietnam, the heavy cotton and polyester of the Korean War-era uniform were replaced with a tropical-weight cotton ripstop that was wind-resistant yet cooler for troops operating in the sweltering heat of Southeast Asian jungles.
Both trousers and jackets were made of this cotton-poplin material for years, until the Army adopted the so-called “Battle Dress Uniform” in the early 1980s. That uniform was made with a nylon-cotton blended material with was more durable and easier to launder than the Vietnam-era combat duds.
But the military was forced to offer a variation of the BDU in cotton ripstop after operations in Grenada proved the nylon-cotton blend material too hot in warmer climates.
Though today’s combat uniforms are made with similar materials to those of the BDU-era, the wars in Iraq and Afghanistan proved that some front-line troops need kit that’s resistant to the flame and flash of roadside bombs and IEDs.
Early on, some troops — including Marines deployed to Iraq — wore flight suits manufactured with flame resistant Nomex during combat operations. But that fabric wasn’t durable enough for the rigors of battle on the ground. So companies developed new, more durable flame-resistant fabrics for combat uniforms like Defender-M and Drifire.
Now all the services offer variants of their standard combat uniforms in flame-resistant material that protects troops against burns from improvised bombs.
3. Combat uniform camouflage
It’s like the 1911 vs. (everything) debate, or the M-16 versus the AK-47 argument.
For decades, the question of camouflage patterns has been as much art as it was science. And over the last half century, the U.S. military has seen no fewer than 11 different patterns bedecking America’s warfighters.
Most Joes in the Vietnam War were clad in olive drab combat uniforms. But special operations troops began using camouflage garments in greater numbers during the war, and acted as the bleeding edge for pattern development within the wider military.
From ARVN Ranger “tiger stripes” to old-school duck hunter camo, the commandos in The ‘Nam proved that breaking up your outline saved lives. With the adoption of the BDU in 1981, the military locked into the service-wide “woodland” camouflage pattern.
In the early ’90s, the services developed desert combat uniform with a so-called “six-color desert” pattern (also known as “chocolate chips”). These uniforms were issued to troops conducting exercises and operations in arid climates and were more widely issued to service members deployed to Operation Desert Storm.
The woodland BDU dominated for more than 20 years until shortly after 9/11. And it was the Marine Corps that took the whole U.S. military in an entirely different direction.
The Corps was the first to adopt a camouflage pattern with so-called “fractal geometry” — otherwise known as “digital camouflage” — that diverges from the curvy lines and solid colors of woodland to a more three-dimensional scheme designed to literally trick the brain. While the Marines adopted a digital woodland pattern and a desert version in 2003, the Army decided to try a single pattern that would work in a variety of environments a year later.
Dubbed the Universal Combat Pattern, or “UCP,” the green-grey pallet flopped, with most soldiers complaining that instead of working in a bunch of environments, it made Joes stand out in all of them. As in Vietnam, special operations troops engaged overseas adopted a commercial pattern dubbed “Multicam,” which harkened back to the analog patterns akin to woodland.
Pressure mounted on the Army to ditch UCP and adopt Multicam, and by 2015, the service abandoned the one-size-fits all digital pattern and adopted Multicam for all its combat garments.
Likewise, the Air Force and Navy experimented with different patterns and pallets since the Army adopted UCP, with the Sea Service issuing a blue digital uniform for its sailors and the Air Force settling on a digital tiger stripe pattern in a UCP pallet. In 2016, the Navy ditched its so-called “blueberry” pattern for one developed by the SEALs — AOR 1 and AOR 2 — which looks similar to the Marine Corps “MARPAT” digital scheme.
The Air Force still issues its Airman Battle Uniform in the digital tiger stripe pattern to all airmen except those deploying to Afghanistan and on joint missions in the combat zone.
4. Combat uniform design
Aside from the rapid development and deployment of new camouflage patterns, some of the most impressive changes to U.S. military combat uniforms have been with their overall design.
Gone is the boxy, ill-fitting combat ensemble of troops slogging through the rice paddies and jungle paths of Southeast Asia. Today’s battle uniform traces its design to the high-tech construction of the extreme outdoor sports world, from high-altitude climbing to remote big game hunting.
Troops in the services now have uniforms that have pre-curved legs and arms, angled and bellowed pockets that stay flat when they’re empty, Velcro closures and adjustable waists. The services even use specially-designed combat shirts that ditch the jacket altogether and use built-in moisture-wicking fabric to keep a trooper’s torso cool under body armor yet provide durable sleeves and arm pockets for gear needed in the fight.
With integrated pockets for knee pads and elbow pads, the new combat uniforms’ design takes “utilitarian” to a whole new level.
5. Combat armor
Aside from the actual clothing an American combat trooper wears, there are a host of new protective items that make up his or her battlefield loadout. These items have evolved exponentially over the last half century, and many uniform manufacturers have supplied protective accessories to integrate with their clothing.
Late in the war, the Vietnam-era soldier or Marine was issued a body armor vest that would protect him against grenade fragments and some pistol rounds. Made of ballistic nylon and fiberglass plates, the armor was best known as the “flak jacket.” It was heavy and didn’t protect against rifle rounds.
In the 1980s, the U.S. military developed a new body armor system using steel plates and Kevlar fabric that could stop a rifle round. First used in combat during Operation Urgent Fury in Grenada, the so-called Personnel Armor System for Ground Troops, or PASGT, was a revolution in personal protection.
Still heavy and bulky, armor evolved over the years since 9/11 to be lighter, with a slimmer profile and much more protective than the flaks of yore. Today’s vests can protect against multiple armor-piercing rifle rounds, shrapnel and pistol shots — all in a vest that weighs a fraction of its PASGT brethren.
Like the armor vest, the “steel pot” of Vietnam has changed dramatically in the last 50 years. The new Army Combat Helmet and Marine Corps Lightweight Helmet can take multiple bullet strikes and shrapnel hits, allow for greater mobility than the Vietnam-era one or the PASGT and now incorporate various attachment points for accessories like night vision goggles, IR strobes and cameras.
