STANAG 4569
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
Kinetic Energy
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 910 m/s
5.56×45mm NATO Ball (M193) at 30 meters with a velocity of 930 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.
