Level 1

Kinetic Energy

7.62×51mm NATO The 7.62×51mm NATO (official NATO nomenclature 7.62 NATO) is a rimless, bottlenecked rifle cartridge. It is a standard for small arms among NATO countries. First developed in the 1950s, the cartridge had first been introduced in U.S. service fo ...

Ball (Ball M80) at 30 meters with velocity 833 m/s 5.56×45mm NATO Ball (SS109) at 30 meters with a velocity of 900 m/s 5.56×45mm NATO Ball (M193) at 30 meters with a velocity of 937 m/s Protection against all three threats must be provided.

Grenade and Mine Blast

Hand grenades, unexploded artillery fragmenting submunitions, and other small anti personnel explosive devices detonated under the vehicle.

Artillery

20 mm FSP (simulating 155 mm 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.) Angle: azimuth 360°; elevation: 0–18°

Level 2

Kinetic Energy

7.62×39mm The 7.62×39mm (aka 7.62 Soviet, formerly .30 Russian Short) round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the worldwide proliferation of Russian SKS and AK-47 pattern rifles, as ...
