The ZSU-23-4 Shilka is directly documented in Iraqi service during the 1990 Gulf War. A U.S. Army article on the Rock Island Arsenal display vehicle states that the Shilka displayed at Memorial Field saw service with the Iraqi Army during Operation Desert Storm and was found abandoned west of Kuwait City.
Public-domain archive records add conflict-specific battlefield evidence. One U.S. National Archives-derived record identifies Marines examining an abandoned Iraqi ZSU-23-4 on the road into Kuwait City during the ground phase of Operation Desert Storm on 24 February 1991, while another places an abandoned Iraqi ZSU-23-4 near burning oil wells west of Kuwait International Airport after the ceasefire.

Timeline
The dated record begins before the ground offensive. A declassified Royal Air Force mission report for 31 January 1991 lists a ZSU-23-4 and support vehicles as a target near 28 degrees 47 minutes north, 48 degrees 16 minutes east, records eight CBU BL755 weapons expended, and assesses one ZSU-23-4 and one truck destroyed.
During the coalition ground phase, archive metadata dated 24 February 1991 records Marines examining an abandoned Iraqi ZSU-23-4 on the road into Kuwait City. On 3 March 1991, after the ceasefire, another archive record places an abandoned Iraqi ZSU-23-4 in the desert west of Kuwait International Airport.

Role in Iraqi service
In the Gulf War record, the Shilka appears as an Iraqi short-range air-defense and force-protection vehicle rather than as a coalition weapon. The U.S. Army article describes the system as providing low-level cover for armored and mechanized divisions, and the Desert Storm evidence places Iraqi vehicles with fielded ground forces in Kuwait.
The surviving records show several evidence types: a museum provenance statement for an Iraqi Army vehicle, operational imagery of abandoned or damaged Iraqi ZSU-23-4s, and an RAF strike report identifying a ZSU-23-4 as a target. Together they support fielding by Iraqi forces during Operation Desert Storm, but they do not establish a single continuous unit history for the vehicles shown in the different records.
