When sourcing armored vehicles, you must verify compliance with international ballistic standards. The most recognized is the VPAM (European) or CEN (BR/VR) scale. For civilian use, CEN B6 (VPAM 7) is the industry standard, capable of stopping 7.62x51mm NATO rounds. For higher threats, CEN B7 (VPAM 9) protects against armor-piercing rounds. Always request independent laboratory test reports (e.g., Beschussamt Mellrichstadt) for both the opaque armor (steel/composites) and transparent armor (glass).
