NATO AEP-55 STANAG 4569 is a NATO Standardization Agreement covering the standards for the "Protection Levels for Occupants of Logistic and Light Armored Vehicles".[1]
The standard covers strikes from kinetic energy, artillery and IED blasts.
Level 1
editKinetic Energy
edit7.62×51mm NATO Ball (Ball M80) at 30 meters with velocity 833 m/s[1][2]
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
editHand grenades, unexploded artillery fragmenting submunitions, and other small anti personnel explosive devices detonated under the vehicle.
Artillery
edit20 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.)[3]
Angle: azimuth 360°; elevation: 0–18°
Level 2
editKinetic Energy
edit7.62×39mm API BZ at 30 meters with 695 m/s[1]
Grenade and Mine Blast Threat
edit6 kg (explosive mass) Blast AT Mine:
2a – Mine Explosion pressure activated under any wheel or track location.
2b – Mine Explosion under center.
Artillery
edit155 mm High Explosive at 80 m
Angle: Azimuth 360°; elevation: 0–22°
Level 3
editKinetic Energy
edit7.62×51mm AP (WC core) at 30 meters with 930 m/s[1]
Angle: Azimuth 360°; elevation 0–30°
Grenade and Mine Blast Threat
edit8 kg (explosive mass) Blast AT Mine:
3a – Mine Explosion pressure activated under any wheel or track location.
3b – Mine Explosion under center.
Artillery
edit155 mm High Explosive at 60 m
Angle: Azimuth 360°; elevation: 0–30°
Level 4
edit
Kinetic Energy
edit14.5×114mm AP / B32 at 200 meters with 911 m/s[1]
Angle: Azimuth 360°; elevation 0°
Artillery
edit155 mm High Explosive at 30 m[4]
Grenade and Mine Blast Threat
edit10 kg (explosive mass) Blast AT Mine:
4a – Mine Explosion pressure activated under any wheel or track location.
4b – Mine Explosion under center.
Level 5
editKinetic Energy
edit25 mm APDS-T (M791) or TLB 073 at 500 m with 1258 m/s[1]
Angle: Frontal arc to centreline: ± 30° sides included, elevation 0°
Artillery
edit155 mm High Explosive at 25 m
Angle: Azimuth 360°; elevation: 0–90°
Level 6
editKinetic Energy
edit30 mm APFSDS or AP at 500 m[5]
Angle: Frontal arc to centreline: ± 30° sides included, elevation 0°
Artillery
edit155 mm High Explosive at 10 m
Angle: Azimuth 360°; elevation: 0–90°
