Happy 250th birthday, Marines! As the Corps honors its legacy, it’s a great opportunity to reflect on the evolution of personal protective equipment (PPE). PPE was designed within the limits of manufacturing abilities at the time and specifically tailored for the threats unique to each era of warfare, to enhance Marine survivability.
Throughout Marine history, PPE, while sometimes uncomfortable and always adding weight, has consistently saved lives. It's through discipline and dedication to the standard of wearing PPE, even grudgingly, that it saves Marines lives.
The Birth of the Leathernecks: Continental Marines
Leather stocks, a 2 inch piece of black shoe leather worn around the neck was designed to give Marines an upright posture. Although Marine Corps legend has often pointed to this as the first piece of PPE for Marines to protect against saber slashes to the neck in close quarters combat. There is no data or historical records available to prove the leather stock protected against saber slashes
World War I: Trench Warfare
Trench warfare was characterized as static fortified ditch networks, enduring stalemates, large artillery barrages, machine-gun fire, and gas attacks. M1 Helmet: Also known as the Brodie, protected against shrapnel from above, reducing head wound fatalities. Pressed from a single piece of steel, the Brodie was a product of early industrial manufacturing, designed to mitigate the dangers of artillery and shrapnel raining down on Marines in static trench lines. The Small Box Respirator (SBR): A technological leap that reduced gas fatalities, by using a charcoal filter and face mask.
World War II: Island-Hopping
The large scale island-hopping campaign was a more dynamic than static trench lines of WWI, small arms fire, increased artillery, naval gunfire in support of troops and air support led to the need for more improved protection. M1 Helmet: Improved on the Brodie, providing better protection against shrapnel and ricochets by using improved metallurgy and mass-production techniques, as a significant improvement over its WWI predecessor, becoming ubiquitous. Marines experimented with camouflage patterns, painting their helmets and uniforms to blend in with the dense jungle foliage. The M1’s more robust and contoured design was better suited for the dynamic combat of World War II. Protective vests: Though experimental, were deemed impractical for wide use. Reflecting the technological constraints of the time, early flak vests were heavy, cumbersome and ineffective in the challenging tropical environments of the Pacific. Still, the desire for this type of protection highlighted a growing awareness of mitigating blast and fragmentation injuries. Footwear: Improved leather boots provided greater ankle support and protection during amphibious landings and prolonged marches through challenging terrain. Korean War: Urban to Cold Weather Mountain Warfare The Korean War was characterized by large conventional battles, the amphibious assault at Inchon, urban warfare, and cold weather warfare in the Chosin Reservoir. M1 Helmet: Continued in use. M-1951 Armored Vest: The first widely issued body armor, made of newly developed ballistic nylon and flexible Doron plates. This design offered improved protection against fragmentation, a common threat in the Korean War’s battles. Cold Weather Gear: Perhaps one of the larger difference from the Korean War and the island hopping campaign of WWII in hot tropical islands, was cold winters on mountainous terrain in Korea. To adapt the Marine Corps developed cold weather gear for the sometimes -30 degree temperatures. The initial cold weather gear was leftover from WWII including the M-1943 Field Jacket and accompanying trousers suitable to winters in Europe, but not necessarily to these extreme conditions. This resulted in the development of cold weather gear including the M-1951 parka with matching trousers, shoe pacs, made of rubber bottomed boots with felt liners, and the additon of Trigger-Finger Mittens.
Vietnam War: Jungle Warfare Vietnam’s warfare was marked by dense jungle combat, urban battles, hidden booby traps, defense of bases, frequent patrols and small arms engagements often with elusive guerrilla forces. M1 Helmet: Continued in use. M-1955 Flak Vest: Made of ballistic nylon with Doron plates, stopped low-velocity fragments. M-1969 Flak Vest: Lighter with improved ventilation, better suited to mobile warfare. The ’69 vest reflected a better understanding of operational demands, aiming to balance protection with the need for mobility and comfort in the humid jungle environment.
Persian Gulf Wars: Desert Warfare with Chemical Threat The leading concern in these conflicts were the adversary’s long range missiles and chemical weapons. To protect Marines the PPE focused on chemical, biological and radiological (CBRN) threats and shrapnel. The Personnel Armor System for Ground Troops (PASGT) was the new standard for this period.
PASGT Helmet: Commonly reffered to as the ‘K-pot’, featured the first Kevlar shell. Replacing the M1 helmet after 45 years of service.
PASGT Kevlar Vests: Was the first kevlar vest system and marked a shift toward more advanced materials, providing better ballistic protection, a necessity for this type of warfare. While specific injury reduction numbers directly attributable to the PASGT are limited, studies on Kevlar-based body armor systems showed a significant decrease in penetrating injuries compared to previous protective vests.
CBRN Protection: Marines frequently trained in full Mission Oriented Protective Posture (MOPP) levels. MOPP gear was developed to protect against chemical threats. Gear included the M17A1/M40 mask, battle dress over garment a charcoal lined suit, rubber gloves and vinyl boots to create a sealed environment. The rigorous MOPP training also highlighted the importance of muscle memory and discipline in preparing for extreme conditions.
Global War on Terror (GWOT): Desert Warfare, Urban Warfare and Counter-Insurgency The characteristics of this warfare changed over the years, but largely this period included a 360-threat environment, urban or populated terrain, enemy small arms fire and the proliferation of improvised explosive device (IED) threats. As the wars evolved PPE adapted to match.
MOPP Gear: The MOPP suit from the Persian Gulf Wars was replaced with the Joint Service Lightweight Integrated Suit Technology (JSLIST), which was lighter, more breathable and used a beaded carbon technology, an improvement on the charcoal lining of previous MOPP gear. It was also designed to integrate better with the rest of PPE and equipment. These improvements made it possible for troops to be in MOPP level 1 during most of the invasion of Iraq.
Uniforms: The traditional woodland patterned Marine Corps combat utility uniform (MCCUU) was gradually replaced by the digital Marine Pattern (MARPAT) MCCUU in the early 2000s, enhancing camouflage effectiveness. In the mid 2000s as a temporary measure to combat burn injuries from the growing IED threat, Marines sometimes wore flight suits for their inherent flame-resistant properties.
By the late 2000’s to provide a more permanent solution to burn prevention Marines adopted the Flame-Resistant Organizational Gear (FROG) suit. This offered superior flame protection, weight and breathability tailored for the harsh desert environment.
The evolution of uniforms reflected a heightened awareness of the specific threats of the GWOT and a greater emphasis on providing protection and heat mitigation.
IED Protection: As the IED threat continued to grow through out the GWOT protection measures continued to evolve. ‘Blast diapers’ made of ballistic fibers worn over the uniform and Kevlar-lined ‘blast boxers’ under the uniform became widely adopted as another layer of protection against IEDs.
Helmet Advancements: The PASGT transitioned to another Kevlar design, the Advanced Combat Helmet (ACH), rated to stop 9mm rounds and fragmentation. Then the Enhanced Combat Helmet (ECH) was adopted, although similar in weight, it was made primarily of ultra-high-molecular-weight polyethylene. The ECH was the first helmet rated to stop up to 7.62mm rounds.
Body Armor: PASGT was phased out as it had limited protection against rifle rounds and was replaced with the Interceptor Body Armor (IBA) or widely referred to as the ‘interceptor vest.’ The IBA included the woven kevlar that provided protection against handgun fire and fragmentation. This was the first vest that included the Enhanced Small Arms Protective Inserts (ESAPI), commonly referred to as ‘SAPI Plates’, which provided protection up to 7.62mm rounds. Then the Modular Tactical Vest (MTV) replaced the IBA for better modularity. This modular system allowed Marines to tailor their protection to the specific threats, operational environment and the evolution of IEDs. The MTV included the back and front ESAPI of the IBA, with the addition of two smaller side ballistic plates called Enhanced Side Ballistic Inserts (ESBI), as an improvement on protection in the 360 threat environment. These plates are also rated up to 7.62mm round protection. Studies on the effectiveness of body armor during the GWOT consistently demonstrated a significant reduction in fatalities and serious injuries from IEDs and small arms fire. As fragmentation and IEDs turned to the leading cause of injury, these protection measures were added to the PPE when going outside the wire.
Looking to the Future
Looking to the future, the Marine Corps strives for continued advancements in PPE, constantly seeking to balance protection with the need for agility and maneuverability. The dream is light weight flexible materials. The Corps is exploring everything from advanced polymers and composite materials to potentially even exoskeletal enhancements. Even with revolutionary technologies the Marine Corps’ grit and iron-clad dedication to discipline remain the cornerstones of success. Knowing that the extra weight can save your life is something all Marines must remember. As the Marines celebrate 250 years, keep up the tradition of holding the standard high, protecting Marines' lives and embracing the innovations that will safeguard them in the battles to come.
“As we look back at our 250 years of excellence, we remember the stories of those who came before us – each era recalling how Marines of their time escaped death because of their protective equipment. Marines then had the same discipline to persist with their PPE that we do now and taking care of our tribe can be as simple as a gear check. I need every one of our Marines to stay in the fight and the cost of comfort could be a Marine’s life.”
Sergeant Major of the Marine Corps, Sgt. Maj. Carlos A. Ruiz
