• 18 USC § 931 — The Federal Body Armor Baseline, Explained

  18 USC § 931 is the federal floor. Convicted violent felons cannot possess body armor. Post-Sessions v. Dimaya (2018), the definition of "crime of violence" narrowed to § 16(a). Here's what that means for sellers and buyers.

• ACH-GEN-II — The Military Helmet Spec LE Actually Cares About

  ACH-GEN-II is the US Army's performance specification for Advanced Combat Helmet and its derivatives. It covers fragmentation V50, 9mm V50, backface deformation, and retention — a tougher spec than NIJ 0106. This guide covers what it specifies and why LE agencies increasingly require it.

• Aramid Fibers — Kevlar vs Twaron vs Heracron

  Para-aramid fibers founded modern body armor — DuPont's Kevlar (1971) and Teijin's Twaron led the market before UHMWPE emerged. This guide compares the four major para-aramid suppliers (DuPont, Teijin, Hyosung, Kolon) and where each is used today.

• ASTM E3141 — The LE Shield Test Method

  ASTM E3141 defines how to test ballistic LE shields — shot placement, velocity measurement, acceptance criteria — the protocol that makes E3347 compliance a defensible certification. This guide covers the test structure and what distinguishes it from NIJ 0108.01's panel-centric methodology.

• ASTM E3347 — The New LE Shield Performance Specification

  ASTM E3347 is the first US performance specification purpose-built for LE ballistic shields. It covers shield body, edges, viewports, fasteners, and weak points — going beyond NIJ 0108.01's panel-only scope. This guide covers what E3347 actually tests and why it's rapidly becoming a procurement requirement.

• Ballistic Ceramics — Alumina vs Silicon Carbide vs Boron Carbide

  Hard armor plates use ceramic strike faces to fracture bullets before they reach the fiber catch layer. Three ceramic families dominate — alumina, silicon carbide, and boron carbide. This guide covers weight, cost, and performance tradeoffs and the suppliers behind each.
