| Minimum Coverage Area |
100% of the shield area must protect against the threat. |
| Backface Deformation |
Maximum allowed deformation: 44 mm (1.75 inches) |
| Test Type |
Single shot testing at designated impact points on shield |
| Use Case |
Personal defense, standard law enforcement use, and general civilian protection. Designed for environments with low-risk handgun threats. |
NIJ HG2 (Enhanced Handgun Protection - Higher Velocity)

| Minimum Coverage Area |
100% of the shield area must protect against the threat. |
| Backface Deformation |
Maximum allowed deformation: 44 mm (1.75 inches) |
| Test Type |
Single shot testing at designated impact points on shield |
| Use Case |
Tactical law enforcement, enhanced personal protection, and environments with higher velocity handgun threats. Ideal for use where more powerful handguns (like .40 S&W and 9mm +P) may be present. |
NIJ RF1 (Rifle Protection - Intermediate Velocity)

~2,700–2,900 ft/s |
| Minimum Coverage Area |
100% of the shield area must protect against the threat. |
| Backface Deformation |
Maximum allowed deformation: 44 mm (1.75 inches) |
| Test Type |
Single shot testing at designated impact points on shield |
| Use Case |
Protection against military or tactical rifles in law enforcement and military operations. Effective against intermediate rifle threats. |
NIJ RF2 (Rifle Protection - Armor-Piercing)
| Specification | Details |
|---|
| Protection Level |
RF2 |
| Tested Threats |
Armor-piercing rifle rounds |
| Example Ammunition |
.30-06 AP (166gr), 7.62mm NATO API |
| Reference Velocity |
~2,800–3,000 ft/s |
| Minimum Coverage Area |
100% of the shield area must protect against the threat. |
| Backface Deformation |
Maximum allowed deformation: 44 mm (1.75 inches) |
| Test Type |
Single shot testing at designated impact points on shield |
| Use Case |
Designed for environments with armor-piercing rifle threats, used in military operations or high-risk tactical operations. |
NIJ RF3 (High-Level Rifle Protection - Military)
| Specification | Details |
|---|
| Protection Level |
RF3 |
| Tested Threats |
High-velocity, armor-piercing military rounds |
| Example Ammunition |
7.62mm NATO API, .50 BMG |
| Reference Velocity |
~3,000–3,200 ft/s |
| Minimum Coverage Area |
100% of the shield area must protect against the threat. |
| Backface Deformation |
Maximum allowed deformation: 44 mm (1.75 inches) |
| Test Type |
Single shot testing at designated impact points on shield |
| Use Case |
Extreme protection for military combat or high-risk tactical operations where .50 BMG or similar threats are present. |

Key Takeaways
- HG1 and HG2 provide protection for handgun threats, with HG2 offering protection against higher-velocity handgun rounds.
- RF1 offers protection for intermediate rifle rounds such as 5.56mm NATO and 7.62mm NATO.
- RF2 and RF3 are designed to stop armor-piercing rifle rounds, with RF3 offering the highest protection, including defense against .50 BMG and other extreme military-grade ammunition.
These updated specifications provide a clear understanding of the protection offered by each level and ensure that ballistic shields are tested rigorously to meet the evolving threats faced by law enforcement, military, and security personnel.
