The right ballistic inserts are important when it comes to your safety. Choosing between LEVEL III+ and LEVEL IV levels of protection affects what threats you can effectively neutralise. In this article, we’ll introduce you to the differences between these levels and help you understand what to look for when making a purchase.
What is the difference between protection levels: LEVEL III+ and LEVEL IV?
LEVEL III+ ballistic inserts are designed to withstand bullets fired from semi-automatic weapons such as AK-47 or AR-15 rifles, including steel-core ammunition. LEVEL IV cartridges, on the other hand, are designed to stop anti-tank (AP) bullets, thus offering the highest level of protection.
The difference is also due to the construction and materials. LEVEL IV cartridges are often heavier due to the extra layers of protection. LEVEL III+ is a compromise between protection and weight that will work well in situations requiring mobility.
Testing and resistance to multiple and single shots
One of the key factors when choosing ballistic inserts is their resistance to different types of fire. LEVEL III+ often offer resistance to multiple shots, making them more versatile on the battlefield. LEVEL IVs, while extremely effective, are usually tested against a single impact by a high penetration bullet.
If your priority is protection in intense gunfire, LEVEL III+ cartridges may be a better choice. For protection against a single shot from a heavy weapon – LEVEL IV are up to the task.
Calibre threats: which bullets stop which levels?
LEVEL III+ ballistic inserts are effective against 7.62×51 mm NATO ammunition and 5.56×45 mm steel cores. LEVEL IV, on the other hand, can cope with more extreme threats, such as 7.62x63mm AP (Springfield M2 rifle) anti-tank rounds.
Choosing the right cartridge depends on the threats you anticipate. If you are operating in an environment where advanced munitions are used, LEVEL IV should be your choice.
Material and construction: from SAPI to ‘swimmer cut’
The materials used for ballistic inserts vary according to the level of protection. LEVEL III+ are often made of lighter ceramic and polyethylene composites, while LEVEL IV require heavier ceramics or ceramic-metal hybrids.
In addition, cartridges can come in different shapes, such as the classic SAPI or the more ergonomic ‘swimmer cut’. The latter facilitate movement and work well in dynamic tactical situations.
Weight and comfort of use depending on protection level
One of the biggest challenges when choosing ballistic inserts is their weight. LEVEL III+ weigh less, making them more comfortable for long wear. LEVEL IV, although heavier, offer the highest protection.
Therefore, if you are operating in situations requiring a high degree of mobility, LEVEL III+ may be a better option. LEVEL IV cartridges are recommended where maximum safety is a priority, even at the expense of comfort.
Export regulations and certificates – what to check before you buy
Ballistic inserts, particularly at LEVEL IV, are subject to strict export regulations. In Poland, it is necessary to obtain a permit from the relevant authorities in order to purchase such equipment. Also make sure that the cartridges you choose are certified in accordance with standards, such as NIJ (National Institute of Justice).
Purchasing a certified product is a guarantee that it will perform at a critical time.
When to choose LEVEL III+ and when to choose LEVEL IV?
The decision between LEVEL III+ and LEVEL IV depends on your needs. If your operations require mobility and frequent movement, the LEVEL III+ will provide protection while maintaining convenience. The LEVEL IV will perform well in high-risk scenarios where stopping an anti-tank missile is crucial.
Cost comparison: does more protection mean more expense?
LEVEL IV ballistic inserts are more expensive than LEVEL III+ due to more advanced materials and higher production costs. However, an investment in LEVEL IV may be necessary in situations where protection from AP projectiles is crucial.
Your protection, your decision
Choosing the right ballistic inserts is a decision that can make all the difference to your safety. LEVEL III+ offer the perfect balance between protection and weight, while LEVEL IV offers unparalleled protection in the toughest conditions. Think through your needs and choose a solution that will give you confidence in any situation.
