The BR-167 is the Soviet 37 mm armor-piercing tracer projectile in the UBR-167 fixed round for the M1939 / 61-K anti-aircraft gun family. Ordnance identification guides tie the BR-167 projectile to the UBR-167 cartridge and the M1939 towed gun, while specialist ammunition references describe the projectile as a spin-stabilized solid shot with a tracer element and no explosive filler.

Ammunition Family Notes

Declassified ordnance guides identify BR-167 as the U.S.S.R. projectile for the UBR-167 fixed AP-T cartridge used with the M1939 / 61-K 37 mm air-defense gun family. The projectile is documented as solid shot, so references distinguish it from the neighboring OR-167 fragmentation-tracer ammunition.
