If you look at the standard set by the National Institute of Justice, you will notice the “A” at all levels. 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 the advantages between these two types of bulletproof vests. At the end of this article, you will also find out which ballistic vest level is relevant to your daily activities.
In 1970, the United States Department of Justice conducted an investigation and study to arrive at an appropriate standard. After various trials, tests, and evaluations, the final strength standard evolved, which today is known 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 rigid quality control, users are confident and confident that the bulletproof vest can provide the protection specified on the label.
The resistance standard is divided into six levels. That is, level 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 the soft armor. This is basically the main difference between level 3 and level 3A body armor. Level 3A belongs to the soft bulletproof vest, 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 the rifles specified in the NIJ standard, the inclusion of + A in the threat level is approved. Once one or more hard armor plates are added to the bullet resistant soft vest, it moves to level 3. Consequently, the higher the level of protection, the heavier and bulkier the vest becomes.
Typically, a level 3A bulletproof vest can withstand 22 long rounds of rifle lead, .380 ACP, 9mm, .40 all-metal jackets, .357 magnum, and other handguns. The level 3 ballistic vest, on the other hand, can withstand 7.62 full metal jacketed bullets and another 48 joules of energy weaponry. This is considered the highest level of protection among the standard endurance capabilities, except for level 4, which are probably custom made vests specially designed to defeat more advanced ammunition.
