Armored Vehicle Standards
Ballistics Specifications describe the ability of a material to stop a projectile. These specifications can apply to any material; this is true of steel, composite, or concrete.
Ballistics specifications are internationally recognized standards used when deciding on the level of protection required. Once the protection level is determined, then the appropriate materials will be selected.
