🛡️ Ballistic Threat Lookup
Choose a common round to see the minimum NIJ armor level rated to stop it — a defensive reference to help you match protection to the threats you face.
🛡️ Look Up the Minimum Armor Level
What is the Ballistic Threat Lookup?
It maps threats to the protection that stops them. Pick a round and the tool returns the minimum NIJ level rated to defeat it, along with a plain-language explanation — so you can understand what a vest or plate's rating actually means for the threats you care about.
Use it alongside the Body Armor Level Guide when comparing gear or deciding what protection you need. It is a defensive, informational reference to the published NIJ standard — always verify ratings with the manufacturer, buy certified gear, and check your local laws, because body armor is regulated in some regions and no armor guarantees safety.
❓ Frequently Asked Questions
What does this tool tell me?
It answers a defensive question: for a given ballistic threat, what is the minimum NIJ armor level rated to defeat it? For example, common 9mm handgun rounds are a Level II threat, while rifle fire requires hard plates at Level III or higher. It's a protection reference, not offensive guidance.
Why can't soft armor stop rifle rounds?
Soft armor works by catching and spreading a bullet's energy across layers of flexible fiber, which is effective against slower, blunter handgun rounds. Rifle rounds travel far faster and carry much more energy, so stopping them requires the rigid, hardened material of a Level III or IV plate.
What is an armor-piercing threat?
Armor-piercing rounds use a hardened core designed to punch through materials that stop ordinary bullets. Defeating them requires the highest hard-plate rating, NIJ Level IV, which is tested against a specific armor-piercing rifle round. Even then, plates are rated for a limited number of hits.
Does the right level guarantee I'm safe?
No. Armor reduces risk against the threats it's rated for, but no armor guarantees safety — placement, multiple hits, angle, and condition all matter, and areas outside the plate are unprotected. Always verify ratings with the manufacturer and the NIJ standard, and check the laws that apply where you live.
