What Body Armor Does The Military Use?
When it comes to military operations, the protection of soldiers is paramount. The body armor they wear is designed to protect them from a variety of threats, including bullets, shrapnel, and other hazards commonly encountered in combat zones.
In this blog, we will take a closer look at “What body armor does the army use?” and explore the different types of armor used by military personnel.

The Evolution of Military Body Armor
Early Developments in Military Armor
Body armor has come a long way since its earliest designs. In ancient times, soldiers wore metal plates or chainmail to protect themselves from arrows and blades. These early armor pieces were heavy and often cumbersome, but they provided essential protection in battle.
As warfare evolved, so did the need for better armor. During the 20th century, the introduction of firearms forced a shift from traditional metal armor to materials capable of withstanding bullets.
The early 20th century saw the development of more advanced armor made from steel. This provided a greater level of protection against high-velocity projectiles.
Technological Advancements
In the late 20th century, the military began to explore more lightweight materials that could offer better protection while maintaining mobility. This led to the development of synthetic fibers such as Kevlar, which is still widely used today.
The introduction of lightweight materials revolutionized the design of body armor. It allows soldiers to remain agile while still being well protected.
What Body Armor Does the Army Use?
Interceptor Body Armor (IBA)
The Interceptor Body Armor (IBA) was one of the first widely issued armor systems introduced to soldiers in the early 2000s.
It featured a vest designed to hold two types of ballistic plates: soft armor and hard armor. The soft armor is made from layers of flexible materials, primarily Kevlar, designed to protect against lower-velocity rounds, such as handgun fire or shrapnel.
On the other hand, the hard armor plates, typically made from ceramic or composite materials, deliver protection against higher-velocity threats like rifle rounds.
The IBA was a significant advancement in military protection. It gave soldiers more comprehensive coverage against a wider range of ballistic threats.
Improved Outer Tactical Vest (IOTV)
Building on the foundation laid by the IBA, the Improved Outer Tactical Vest (IOTV) was developed to offer better protection and comfort.
One of the most notable improvements was the vest’s adjustable features, which allowed for a more tailored fit across a wider range of body sizes. This made the IOTV a more versatile and effective system, especially for soldiers of varying builds.
Additionally, the IOTV included hard armor plates capable of withstanding high-velocity rifle rounds. This makes it even more suitable for a range of combat scenarios. The design improvements and added protection made the IOTV a key component of military operations.
Soldier Plate Carrier System (SPCS)
The Soldier Plate Carrier System (SPCS) is a lightweight and modular armor system designed for specialized military operations.
Unlike the heavier IOTV, the SPCS offers soldiers the ability to modify their protection based on the mission at hand. For mobility-focused tasks, soldiers can wear just the basic armor plates, which provide vital protection against smaller threats.
However, if they face a more intense combat situation, the system allows for the addition of extra armor components. This flexibility has made the SPCS especially popular among special forces and units that need to prioritize agility and speed while still guaranteeing sufficient protection in hostile environments.
Enhanced Small Arms Protective Insert (ESAPI)
The Enhanced Small Arms Protective Insert (ESAPI) is a type of hard ceramic plate that plays a critical role in providing advanced protection against high-velocity rifle rounds. These plates are inserted into the armor vest, usually in combination with other systems like the IOTV, to enhance the overall protection of the soldier.
The ESAPI plates are specifically designed to absorb the shock from powerful bullets and distribute the force over a wider area. They are a vital component of modern military armor. They offer superior protection and make sure that soldiers are well-protected against the most dangerous projectiles they may face during combat.
