Public evidence places the 2S1 Gvozdika in Iraqi service during the 1990 Gulf War. A U.S. Army photograph by SSgt. Robert L. Reeve, preserved on Wikimedia Commons with Defense Visual Information metadata, identifies an M-1974 122 mm self-propelled howitzer of the Iraqi Republican Guard abandoned during Operation Desert Storm in Kuwait on February 28, 1991.
A second public-domain archive entry, mirroring U.S. National Archives material, identifies an Iraqi M-1974 (2S1) self-propelled 122 mm howitzer alongside a road after being destroyed during Operation Desert Storm in Kuwait. The American Heritage Museum also lists a 2S1 Gvozdika from Iraq in its Gulf War exhibit, separately supporting the type's association with Iraqi Gulf War materiel.

Timeline
The weapon's documented Gulf War record is concentrated at the end of the coalition ground campaign. Iraq invaded Kuwait on August 2, 1990; Operation Desert Storm began in January 1991; and by February 28, 1991, coalition operations had left many Iraqi formations surrendering, retreating, or abandoning equipment in Kuwait and along withdrawal routes.
The dated 2S1 evidence fits that end-of-campaign pattern. The Reeve photograph is dated February 28, 1991 and identifies the vehicle as an Iraqi Republican Guard M-1974 abandoned during Operation Desert Storm. The NARA-linked archive image records another Iraqi M-1974 (2S1) destroyed during the same operation in Kuwait.

Battlefield role
In Iraqi service, the 2S1 Gvozdika represented tracked 122 mm self-propelled artillery. The available Gulf War sources directly document the system as Iraqi battlefield equipment rather than describing a specific fire mission. For that reason, the strongest source-backed claim is that Iraqi forces fielded the system and that coalition or post-battle imagery documented abandoned, destroyed, or captured examples during Operation Desert Storm.
The Republican Guard photograph is especially specific about operator context: it identifies the abandoned vehicle as belonging to the Iraqi Republican Guard. GlobalSecurity's 1991 order-of-battle overview places Republican Guard divisions in the Kuwaiti Theater of Operations at the start of the coalition ground campaign, providing theater context for the photographed vehicle without independently proving a particular 2S1 engagement.
The evidence separates fielding from firing. The image and museum sources support Iraqi possession, deployment, loss, and capture/display context in the 1990 Gulf War; they do not by themselves establish when or where a 2S1 battery fired during the campaign.
