GBRS Group Ballistic Plate Level III ICW & GT Testing Part 3

Published on March 7, 2022
Duration: 4:19

This video details a rigorous ballistic testing protocol for GBRS Group's Level III ICW Special Threat Plates. The tests involve firing 5.56mm, 9mm, and 5.56mm M855 green tip ammunition into the plates mounted on ballistic gel torsos. Expert analysis focuses on backface deformation and the potential for blunt force trauma, even without penetration, highlighting the importance of soft armor backers. The assessment concludes with a positive impression of the plates' performance relative to their weight and cost.

Quick Summary

GBRS Group Level III ICW Special Threat Plates were tested with 5.56mm, 9mm, and M855 green tip ammunition. While the plates prevented penetration, significant backface deformation was observed, highlighting the risk of blunt force trauma. Adding a soft armor backer is recommended to mitigate this energy transfer and reduce potential internal injuries.

Frequently Asked Questions

What types of ammunition were used to test the GBRS Group Level III ICW plates?

The GBRS Group Level III ICW Special Threat Plates were tested against 5.56mm, 9mm, and 5.56mm M855 green tip ammunition. These tests aimed to evaluate the plates' ability to stop projectiles and the resulting energy transfer.

What is backface deformation and why is it important in ballistic testing?

Backface deformation refers to the inward displacement of the armor plate and the resulting impact on the material behind it, like ballistic gel. Significant deformation indicates substantial energy transfer, which can cause severe blunt force trauma to the wearer, even if the plate isn't penetrated.

Can a ballistic plate stop a bullet without causing injury?

While a ballistic plate can prevent penetration, the immense energy transferred upon impact can cause serious internal injuries like broken ribs, cracked sternums, and internal bleeding. This blunt force trauma is a critical consideration in armor system effectiveness.

What is the role of a soft armor backer with hard plates?

A soft armor backer acts as a crucial buffer behind a hard ballistic plate. It helps absorb and dissipate the impact energy, significantly reducing backface deformation and the severity of blunt force trauma that the wearer might experience.
