The 30 mm x 165 HEI-T round is a Soviet-origin high-explosive incendiary tracer cartridge in the 30x165 mm autocannon family, with the 3UOR6 designation used for a closely documented Russian-service round. 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.

Round Construction And Identification

The HEI-T cartridge combines explosive, incendiary, and tracer functions in a 30x165 mm steel-cased round. Sources use both commercial HEI-T wording and Russian-service designation language, so the table separates what each evidence lane supports.

Evidence laneWhat it supportsReader note
Commercial HEI-T catalogsSTV GROUP, MSM Group, and Yugoimport describe 30x165 mm HEI-T ammunition for 2A38/2A42/2A72-family guns.These sources support the current product designation, compatibility, muzzle velocity, tracer, self-destruction, and cartridge construction data.
3UOR6 designationMETIS identifies 3UOR6 / 3УОР6 as a Soviet-era 30x165 mm HEI-T round with an A-670M fuze and steel cartridge case.This supports the alias and designation context without treating every commercial HEI-T cartridge as the same production lot.
Explosive-ordnance contextThe GICHD Ukraine guide describes A-670M fuzes on 30x165 mm HE-I and tracer rounds and notes that such fuzes are found as AXO on cannon rounds such as 3UOR6.This supports identification and safety context, but it is not used here as a conflict-use row because the guide does not assign this exact round to a side or operator.
