How are Level 3 and 3A bulletproof vests different?
Looking at the standard set by the National Institute of Justice, you’ll notice the “A” at each level. For example, there are level 3 and 3A bulletproof vests. This raises many questions for users, especially those who are new to this type of protective clothing.
In this article you will discover the difference and advantages between these two types of bulletproof vests. At the end of this article, you will also find out which level of ballistic vest is relevant to your daily activities.
In 1970, the US Department of Justice conducted an investigation and study to arrive at an appropriate standard. After various trials, tests and evaluations, the ultimate strength standard evolved which is known today as the National Institute Standard 0101.
This standard was implemented in 1987 and to this day is the main standard used worldwide for bulletproof vests. Coupled with strict quality control, users are assured and confident that the bulletproof vest can provide the protection specified on the label.
The resistance standard is divided into six levels. That is, levels 1, 1A, 2, 2A, 3, 3A and 4. Levels 1 to 3A are considered part of the soft armor, while levels 3 and 4 belong to the hard armor. Hard body armor is designed to repel very powerful ammunition. This type of ballistic vest contains hard armor plates that are inserted into the pockets of soft bulletproof vests. This is basically the main difference between a level 3 and level 3A bulletproof vest. Level 3A belongs to soft bulletproof vests while level 3 is hard armor.
Hard plates require the conjunction of soft ballistic vests to be considered hard body armor. This means that after testing for the Rugged Vest for an additional caliber and also for those rifles specified in the NIJ standard, +A is approved for inclusion in the threat level. Once a hard armor plate or plates are added to the soft flak vest, it becomes level 3. Consequently, the higher the protection level, the heavier and bulkier the vest becomes.
Typically, a level 3A body armor can withstand lead bullets from .22 long rifles, .380 ACP, 9mm, .40 full metal jackets, .357 magnums, and other handguns. The level 3 ballistic vest, on the other hand, can withstand 7.62 metal-jacketed bullets and another 48 joules of energy weaponry. This is considered to be the highest level of protection among standard resistance capabilities, except for level 4, which are probably custom-made vests specially designed to defeat more advanced ammunition.
