Direct proof of use
Oryx documents 122 mm D-30 howitzers in the Yemeni Army inventory before the Houthi takeover of Yemen in 2014 and 2015. The same inventory states that it was compiled to clarify equipment available to Yemeni parties on the battlefield, which supports a conservative conflict-use claim for inherited D-30 fielding during the 2014 Yemen Civil War.
The source-backed Yemen claim is battlefield availability from former Yemeni Army stocks. The reviewed public sources do not identify a specific D-30 crew, firing location, loss, capture, or post-2015 transfer shipment, and they do not assign the listed D-30s exclusively to one faction.

Timeline
The conflict phase represented here began with the Houthi takeover of Sanaa in September 2014 and widened after the Saudi-led coalition began military operations in March 2015. Oryx's September 2015 inventory then placed the D-30 among pre-war Yemeni Army towed artillery relevant to the battlefield equipment pool after the takeover.
No source used for this page establishes a later D-30 acquisition route or a dated artillery engagement using the gun. The dated evidence centers on the 2014-2015 collapse of Yemeni state control and the September 2015 documentation of legacy artillery stocks.

Battlefield role
The D-30 is a 122 mm towed howitzer. U.S. Army PM CAS describes the D-30 as a Warsaw Pact-designed howitzer with a 15.4 km maximum range, 21.9 km assisted range, 360-degree traverse on a three-leg stabilizing system, and a maximum rate of fire of 10-12 rounds per minute.
In Yemen, those characteristics support the catalog role of towed artillery fire support. Because the direct Yemen evidence is an inherited-stock inventory rather than incident reporting, the side attribution is broad: the parent catalog row maps the weapon to Houthi-aligned forces and Yemeni government and coalition forces as battlefield parties drawing from or encountering former state stocks.
