Body Armor Backface Deformation: An Overlooked Metric for Optimal Protection
This article explores the critical yet often overlooked metric of body armor backface deformation (BFD). While penetration resistance is essential, BFD measures the armor’s impact on the wearer, addressing blunt force trauma, internal injuries, and reduced operational capability. It highlights why procurement teams should assess average deformation, performance consistency, and real-world wear. Understanding BFD alongside ballistic resistance ensures optimal protection and enhances officer survivability and performance readiness.
