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]

Shooting tests against Polish uparmoured level 4 KTO Rosomak IFV

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[5][edit]

Kinetic Energy[edit]

30 mm APFSDS or AP at 500 m

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°
