Public documentation places the 2S1 Gvozdika in Yemen's war through inventory and force-assessment evidence rather than a clearly dated firing incident. Oryx's 2015 handbook of pre-war Yemeni fighting vehicles lists the 122 mm 2S1 Gvozdika under Yemeni self-propelled artillery and states that the list was intended to clarify military equipment available to Yemeni parties on the battlefield after the Houthi takeover of 2014 and 2015.
Defense Express, citing The Military Balance 2024, later described the internationally recognized Yemeni government's forces as operating heavy weapons that included 2S1 Gvozdika self-propelled howitzers. That source supports fielding by the Yemeni government and coalition side during the ongoing civil-war context, but it does not identify a specific unit, location, or firing date for an individual 2S1.

Timeline
The relevant public timeline begins with legacy Yemeni Army holdings at the start of the war. Oryx published its pre-war fighting-vehicle handbook in September 2015, after the Houthi takeover and coalition intervention had already split the country's armed forces and made pre-war stocks part of the battlefield-equipment picture.
By April 2025, Defense Express assessed that anti-Houthi government-aligned forces could again enter a land-warfare phase and listed 2S1 Gvozdikas among the heavy weapons operated by government forces. The same article placed that assessment after the 2018 Stockholm Agreement and the long lull in major ground fighting around Hodeidah.

Battlefield role
Within the Yemen conflict record, the 2S1 appears as conventional tube artillery attached to legacy Yemeni Army and government-force heavy-weapons holdings. The system's cataloged role is mobile indirect fire support: a tracked, armored 122 mm self-propelled howitzer able to accompany mechanized formations more readily than a towed gun.
The available sources support fielding and availability, not a detailed incident history. Oryx documents that the type was present in the Yemeni Army inventory before the 2014-2015 split, while Defense Express/IISS identifies it among government-force equipment in the later conflict. Those claims should be separated from claims about individual shelling events, which the current source set does not directly establish.
This makes the 2S1 part of the war's broader heavy-artillery layer alongside tanks, armored personnel carriers, towed guns, and rocket artillery. Its significance in the catalog is the continued appearance of Soviet-standard 122 mm self-propelled artillery in a fragmented civil war where control of pre-war state arsenals and later government-aligned formations shaped the equipment record.
