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
[edit]Kinetic Energy
[edit]7.62×51mm 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
[edit]Hand grenades, unexploded artillery fragmenting submunitions, and other small anti personnel explosive devices detonated under the vehicle.
Artillery
[edit]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.)[3]
Angle: azimuth 360°; elevation: 0–18°
Level 2
[edit]Kinetic Energy
[edit]7.62×39mm API BZ at 30 meters with 695 m/s[1]
Grenade and Mine Blast Threat
[edit]6 kg (explosive mass) Blast AT Mine:
2a – Mine Explosion pressure activated under any wheel or track location.
2b – Mine Explosion under center.
Artillery
[edit]155 mm High Explosive at 80 m
Angle: Azimuth 360°; elevation: 0–22°
Level 3
[edit]Kinetic Energy
[edit]7.62×51mm AP (WC core) at 30 meters with 930 m/s[1]
Angle: Azimuth 360°; elevation 0–30°
Grenade and Mine Blast Threat
[edit]8 kg (explosive mass) Blast AT Mine:
3a – Mine Explosion pressure activated under any wheel or track location.
3b – Mine Explosion under center.
Artillery
[edit]155 mm High Explosive at 60 m
Angle: Azimuth 360°; elevation: 0–30°
Level 4
[edit]
Kinetic Energy
[edit]14.5×114mm AP / B32 at 200 meters with 911 m/s[1]
Angle: Azimuth 360°; elevation 0°
Artillery
[edit]155 mm High Explosive at 30 m[4]
Grenade and Mine Blast Threat
[edit]10 kg (explosive mass) Blast AT Mine:
4a – Mine Explosion pressure activated under any wheel or track location.
4b – Mine Explosion under center.
Level 5
[edit]Kinetic Energy
[edit]25 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
[edit]155 mm High Explosive at 25 m
Angle: Azimuth 360°; elevation: 0–90°
Level 6
[edit]Kinetic Energy
[edit]30 mm APFSDS or AP at 500 m[5]
Angle: Frontal arc to centreline: ± 30° sides included, elevation 0°
Artillery
[edit]155 mm High Explosive at 10 m
Angle: Azimuth 360°; elevation: 0–90°
