The M114 appears in the 2014 Yemen Civil War through legacy Yemeni Army stocks and Houthi-aligned public display evidence. Oryx's pre-war Yemeni equipment inventory lists the 155 mm M114 howitzer among Yemeni towed artillery and states that the inventory was intended to clarify equipment available to Yemeni battlefield parties after the Houthi takeover.
A September 2022 open-source thread on the Houthi parade in Hodeidah identified U.S.-made 155 mm M114 howitzers among displayed towed artillery. That evidence supports Houthi-aligned fielding or display during the war, but it does not identify a specific dated M114 firing incident.

Dated milestones
Before the 2014-2015 Houthi takeover, Yemen had a small number of M114 155 mm howitzers in its conventional artillery inventory. A CSIS assessment of Yemeni forces, drawing on IISS and Jane's estimates, listed 15 M-114 155 mm weapons under one count and 10 under another, placing the type in Yemeni Army stocks years before the current civil-war phase.
After Houthi-aligned forces took Sanaa and state stocks fractured among battlefield parties, Oryx listed the M114 in the pre-war equipment set available in the conflict environment. On September 2, 2022, the Hodeidah parade thread identified M114 howitzers among the Houthi display.

Use pattern
The Yemen-war record for the M114 is best treated as legacy artillery fielding rather than a newly supplied system. The howitzers were already present in Yemeni stocks before the Houthi takeover, and the strongest public wartime evidence places examples with Houthi-aligned forces in a parade display at Hodeidah.
Because the cited sources do not document an individual M114 fire mission, target, or battle-damage result, the record should not be read as proof of a specific artillery engagement. It supports the narrower conclusion that M114s were among the heavy towed artillery available to Yemeni battlefield parties and visibly displayed by Houthi-aligned forces during the conflict.
