Direct proof of use
The documented conflict-use claim is narrow: Conflict Armament Research recorded one 30 x 165 mm medium-calibre cartridge ammunition item in the Iraq portion of its Islamic State materiel sample. The report places that sample inside its field investigations of weapons and ammunition captured from Islamic State forces in Iraq and Syria from 2014 to 2017.
The report does not identify the exact 30 x 165 mm projectile variant, the gun or vehicle associated with the cartridge, or a specific firing incident. For this entry, the supported claim is therefore documented Islamic State possession or recovery of the ammunition family in Iraq, not confirmed battlefield firing by a named platform.

Timeline
CAR's report was published in December 2017 after field investigation teams deployed across Islamic State frontline positions in Iraq and Syria between July 2014 and November 2017. Its ammunition tables list one 30 x 165 mm item in the Iraq sample.
Because the public table aggregates the item within the report sample, it does not give a recovery date, storage site, battlefield location, or chain of custody specific to the single 30 x 165 mm cartridge.

Narrative
30x165 mm ammunition is the Soviet-pattern cartridge family used by several 30 mm autocannon lines, including the 2A38, 2A42, and 2A72 families. Manufacturer and reference sources tie those guns to vehicle and air-defense installations such as BMP-2, BMP-3, BMD-2, BTR-80A, and Tunguska-family systems.
In the Islamic State conflict record, however, CAR's evidence stops at one medium-calibre cartridge item in Iraq. The catalog should not infer which autocannon, armored vehicle, or ammunition subtype was connected to that item unless a separate source documents it.
