Choosing the correct body armor can be a challenge of tricky tradeoffs. Steel plated body armor often stops one kind of low-powered AR-15 round from penetrating the vest, but not another. Steel plates are thick but lightweight, while polymer and ceramic plates are thin but heavy. Which classification is “right” for a given application will depend on what the goal is for the vest to accomplish, and what the desired impact and protective qualities are.
Here are some criteria to consider in selecting the best armor:
Design: How visible is the body armor to other people? While anti-spall coating protects against the shrapnel that can sometimes occur when there is an impact or violent throw, a well-designed body armor provides minimum visibility and maximum protection. Often, if the vest is not well-made, it will have metal plates with poor design and inadequate amounts of anti-spall coating. This is the reason that police officers to wear body armor designed specifically for their line of work. Tactical vests offer protection and a high level of concealment. They are made of lightweight, high density polyethylene armor which is not only extremely durable, but it is practically impossible to tell if it’s there at all.
Impact rating: Will a bulletproof body armor stop the shot if it stops the attacker? Some people argue that armor stops more shots than it causes, which is true. However, it really depends on what the attacker is shooting at. If you are being attacked by high velocity rounds from a long range weapon, stopping the bullet in its tracks is unlikely. However, if you are being attacked by a knife or something of the like, stopping the threat before it does serious bodily harm may be the best way to go.
How effective is body armor against firearms and other threats?
Penetration: How effective is body armor against firearms and other threats? Remember that this is a vest, not a bulletproof vest. It is usually rated by the thickness of the material used to construct the garment. Anything less than six inches is considered extremely inadequate. Thinner material will not hold up to high caliber rounds, so thin vests offer little to no protection. Likewise, if the threat comes from a closer range, thicker materials are better because they will prevent the attacker from getting close enough to do much damage.
Spalling: How effective is this type of armor when impacting soft body or personnel? The basic physics of bulletproof vests says that they will stop the bullet if it hits the target at a precisely angled angle. However, soft vest materials do not offer this angle. Therefore, these vests are ineffective against people who are moving quickly, especially if they are running from you. Furthermore, people tend to move around while in a moving vehicle, which also decreases their effectiveness. However, if a soft vest is installed in the driver’s seat, this is probably good enough if the shooter is sitting behind the shot.
how bulletproof vests stop rounds
When evaluating whether it is thick enough or not, it is good to look at how bulletproof vests stop rounds in the same manner. For instance, an ar500 armor will stop a bullet that is traveling at a velocity of 2200 feet per second if it is hit directly between the eyes with a lead head bullet at the distance of twelve inches. Although the round is traveling at such high velocity, the steel vest does not split into sharp steel particles or splinters of steel upon impact. This is due to the presence of martensite, which cause the steel to contract, rather than break upon contact with a bullet.
