Protection LevelsDefinition of Protection: Based on ballistic material providing a 90% probability of protection from the threat (established by STANAG 4164).Threat Level 1 (Rifle)Artillery Simulator: 20mm FSP (simulating 155mm threat) at 520 m/sec from a distance of 100 meters. Due to very low probability of a large fragment retaining enough velocity at these distances, STANAG 4569 makes this optional.Ammunition: 5.56mm x 45 M193 BallDistance: 30 metersProjectile Weight: 3.56 gramsVelocity: 937 m/secEnergy: 1,563 JoulesAmmunition: 5.56mm x 45 SS109 (M855) (DM11) (NATO)Distance: 30 metersProjectile Weight: 4 gramsVelocity: 900 m/secEnergy: 1,620 JoulesAmmunition: 7.62mm x 51 M80 Ball (NATO)Distance: 30 metersProjectile Weight: 9.5 gramsVelocity: 833 m/secEnergy: 3,296 JoulesThreat Level 2 (Infantry Rifle)Artillery Simulator: 20mm FSP (simulating 155mm threat) at 630 m/sec from a distance of 80 meters. Due to very low probability of a large fragment retaining enough velocity at these distances, STANAG 4569 makes this optional.Ammunition: 7.62mm x 39 API BZDistance: 30 metersProjectile Weight: 7.77 gramsVelocity: 695 m/secEnergy: 1,877 JoulesThreat Level 3 (Sniper Rifle)Artillery Simulator: 20mm FSP (simulating 155mm threat) at 770 m/sec from a distance of 60 meters. Due to very low probability of a large fragment retaining enough velocity at these distances, STANAG 4569 makes this optional.Ammunition: 7.62mm x 54R B32 Armor Piercing-InciendaryProjectile Weight: 10 gramsDistance: 30 metersVelocity: 854 m/secEnergy: 3,647 JoulesAmmunition: 7.62mm x 51 AP M993 (WC Core)Projectile Weight: 8.4 gramsDistance: 30 metersVelocity: 930 m/secEnergy: 3,633 JoulesThreat Level 4 (Heavy Machine Gun)Artillery Simulator: 20mm FSP (simulating 155mm threat) at 960 m/sec from a distance of 25 meters.Ammunition: 14.5mm x 114 B32 Armor Piercing-InciendaryDistance: 200 metersProjectile Weight: 63.4 gramsVelocity: 911 m/secEnergy: 26,308 JoulesThreat Level 5 (Automatic Cannon)Artillery Simulator: 20mm FSP (simulating 155mm threat) at 960 m/sec from a distance of 25 meters.Ammunition: 25mm x 137 APDS-T PMB 073Distance: 500 metersProjectile Weight: 121.5 grams (W alloy)Velocity: 1,258 m/secEnergy: 96,140 Joules
