"AK-47 rated" is not a complete ballistic specification. A useful claim names the exact 7.62x39 projectile (FMJ, mild steel core or API) and the test conditions behind it.
A range day can confirm part of a plate's performance, but it cannot replace model-specific documentation on threats, test conditions, dimensions, fit, and warranty support.
Choose armor around documented threats, movement requirements, and wearer needs. There is no universal best plate, only the system that meets the mission and can be fitted, issued, and supported consistently.
Once a year, wipe each plate with a soft damp cloth and let it dry fully before storage. Keep armor dry, out of prolonged heat, and out from under heavy gear.
A department armor order affects purchasing, logistics, training, and the people who wear it. A documented process helps your team compare vendors fairly and field equipment with fewer surprises.
NIJ 0101.07 uses RF1, RF2 and RF3 rifle-threat designations, while older requirements use Level III and Level IV. Level III+ and III++ are not official NIJ levels, so compare plates on documented rounds, reports and...
Treat armor as a department program, not a one-time purchase. Count the direct acquisition cost plus the recurring work to fit, procure, receive, issue, track and retire equipment.
Criticism of classic bare steel armor has a real basis, but a plate should not be accepted or rejected on its core material alone. Evaluate the complete system and the documentation behind the exact model.
