MICH vs ACH vs FAST — Which Helmet, and Why the Names Matter
These three names represent related but distinct helmet programs. A guide to the lineage, current shape differences, and which procurement document you're actually reading.
MICH vs ACH vs FAST — Which Helmet
Three helmet names that routinely get used as synonyms, despite representing distinct programs, shell geometries, and procurement paths. Getting them mixed up in an RFP can pull in the wrong vendor or the wrong SKU.
MICH — Modular Integrated Communications Helmet
Origin: SOCOM program, early 2000s, targeting improved comms integration over PASGT.
What it is: A helmet geometry and procurement program, not strictly a spec. The MICH name refers to the early generation of cut-above-the-ear shells that replaced PASGT in SOCOM.
Where you still see the name: Procurement documents referencing "MICH 2000 / 2001 / 2002" (size and cut variants). These are aged specs; modern SOCOM has moved past them.
ACH — Advanced Combat Helmet
Origin: US Army program, 2003, to standardize the MICH-lineage shell across the regular Army.
What it is: A program + specification (now ACH-GEN-II). Defines ballistic performance, pad system, retention, and cut. Still the primary US Army ground combat helmet.
Cut: Mid-cut above the ear for in-ear comms. Similar to MICH but with program-specific detailing.
Where you see the name: Most US ground-combat procurement; most LE procurements that reference "ACH-compliant" helmets.
FAST — Future Assault Shell Technology
Origin: Ops-Core commercial program, late 2000s. FAST is a trademarked product line, not a government spec.
What it is: A family of commercial ballistic helmets — FAST Base Jump, FAST SF (Super High cut), FAST MT, etc. High-cut is the original differentiator; Ops-Core is now part of Gentex.
Cut: High-cut above the ear, aggressive geometry, maximum rails + NVG compatibility.
Where you see the name: SOCOM procurement, LE tactical teams, commercial sales. If someone says "I'm wearing a FAST," they're wearing an Ops-Core product.
So — MICH, ACH, or FAST?
For LE procurement: you probably want "ACH-GEN-II compliant, high-cut preferred." This language captures the spec performance envelope while allowing FAST and similar high-cut products to compete.
For mil procurement: the program of record specifies the exact helmet. ACH-GEN-II is the current Army baseline.
For SOCOM / SOF: program-specific. FAST-pattern high-cut dominates; ACH-GEN-II remains the ballistic floor.
What the OEMs call these
When you see a product name, it's a commercial branding decision:
- Ops-Core — FAST, FAST SF, FAST XP
- Team Wendy — EXFIL (their high-cut line), EPIC (mid-cut)
- Galvion (formerly Revision) — Batlskin (high-cut)
- Gentex — multiple including FAST (since Ops-Core acquisition), ACH contract variants
- 3M Ceradyne — ACH variants, contract-specific
- Hard Head Veterans — ATE (mid-cut), GATE
A product branded "EXFIL" is a Team Wendy high-cut; a product branded "FAST" is an Ops-Core high-cut. Neither is itself a certification — they are commercial lines typically certified to NIJ 0106 Level II and meeting ACH-GEN-II.
RFP language tips
Avoid:
- "MICH-compatible" — ambiguous; which MICH generation?
- "FAST-style" — not a spec; protects only Ops-Core
- "ACH" alone — doesn't specify the current generation
Use:
- "NIJ 0106 Level II certified, meeting ACH-GEN-II ballistic performance criteria, high-cut (FAST-profile or equivalent) geometry"
This captures the spec envelope, the modern cut preference, and allows competition.
