Manufacturer and military references describe separate-loading HE projectiles with full or reduced propelling charges, while U.S. security-assistance reporting documents 122 mm artillery rounds among ammunition committed to Ukraine and TWZ reporting describes a pair of 122 mm rounds as a standard AQ-400 Scythe payload.

STV GROUP, MSM Group, Yugoimport, METIS, and ordnance references tie the cartridge family to 2A38, 2A42, and 2A72 automatic cannons, making the round relevant to BMP-2, BMP-3, BMD-family, BTR-80A, Tunguska, and other 30x165 mm gun platforms.
