Definition 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 Ball
Distance: 30 meters
Projectile Weight: 3.56 grams
Velocity: 937 m/sec
Energy: 1,563 Joules

Ammunition: 5.56mm x 45 SS109 (M855) (DM11) (NATO)
Distance: 30 meters
Projectile Weight: 4 grams
Velocity: 900 m/sec
Energy: 1,620 Joules

Ammunition: 7.62mm x 51 M80 Ball (NATO)
Distance: 30 meters
Projectile Weight: 9.5 grams
Velocity: 833 m/sec
Energy: 3,296 Joules

Threat 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 BZ
Distance: 30 meters
Projectile Weight: 7.77 grams
Velocity: 695 m/sec
Energy: 1,877 Joules

Threat 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-Inciendary
Projectile Weight: 10 grams
Distance: 30 meters
Velocity: 854 m/sec
Energy: 3,647 Joules
