Uckily advanced ceramic options have proven to be lighter and perform just as well. In our testing with next-generation metals, we are adding 7-15 lbs depending on desired bulletproof helmet coverage to defeat M80 ball at normal velocities with safe backface deformation upon impact. With advances in material fibers, metals, and ceramic armors, the weight required to achieve a true rifle rated ballistic helmet climbs drastically with each NIJ rating achieved. What about these so-called bulletproof helmets? I want a ballistic helmet level IV! Well so do we here at Hard Head Veterans for our ATE ballistic helmet, but there is the little issue of weight. Additionally, there are unique armor sets found on ships, tanks, and other vehicles that conform to their own standards, usually classified to what they can actually defeat and resist threat wise. The National Institute of Justice or NIJ publishes these levels and are the industry standard for most armors. Some armor has extreme capabilities of the resistance offered and we use various rating systems to explain this resistance. As you can see in the case of the up-armored HMMWV, penetrations were achieved on both the "bulletproof" glass and some of the hard-armor. With enough sustained fire or the use of dedicated ammo, just about any type of armor ceases to actually be bulletproof. Lesson Number One with so-called bulletproof helmets, vests, or vehicle armor is that they are not impenetrable. There is only one thing that we currently know of that is truly bulletproof, and that is Superman. Merriam-Webster defines the word bulletproof as being "impenetrable to bullets". There are bullet-resistant helmets and armor, but helmets that are positively bulletproof, meaning they will stop every single bullet fired into them is a misuse of the term bulletproof. There is really no such thing as bulletproof helmets or any armor for that matter. The National Institute of Justice (NIJ) uses a rating system to classify various levels of body armor. Additionally, some military tanks, ships and other vehicles use unique forms of armor conforming to separate standards that typically classify what they can resist. Some armor has higher degrees of effectiveness than others. However, when the number of projectiles is minimal, many of these items effectively resist the impact of most incoming bullets. When faced with powerful weaponry, ammo and enough sustained fire, all body armor is vulnerable to some degree. Understanding the difference between the concepts is critical for those using these items as protection. A more accurate description would entail the term "bullet-resistant," as these objects are not entirely impenetrable.
The word "bulletproof" is often misused, especially when discussing helmets or vests.
