Direct proof of use
The FH70 appears in the 2014 Yemen Civil War record through Saudi border-artillery use. Arms Trade Watch's land-war survey says the Saudi Army deployed artillery near the Yemen border to shell targets in Yemen and identifies the older FH70 155 mm towed howitzer as still in active use near the border, attributing the FH70 point to the French military intelligence agency's 25 September 2018 note on Yemen's security situation.
The public sourcing supports theater-level use by Saudi forces, not a named FH70 battery or a specific individual strike. Disclose's publication of the DRM documents and AFP coverage through Voice of America corroborate the broader leaked-document context for French intelligence reporting on French and European weapons in the Yemen war, while the FH70-specific active-use statement is carried by Arms Trade Watch.

Timeline
Saudi Arabia and coalition partners intervened in Yemen in March 2015 after Houthi-aligned forces advanced against the internationally recognized government. The northern border, especially the Saada area, became a sustained battle zone involving Houthi raids, Saudi and Saudi-backed operations, and artillery fire from positions near the border.
On 25 September 2018, according to the document description published by Disclose and cited by Arms Trade Watch, France's military intelligence agency prepared a Yemen security report mapping French-made and European-origin weapons in the conflict. Arms Trade Watch uses that report to identify FH70 155 mm towed howitzers as active near the Saudi-Yemeni border.

Operational role
In this conflict record, the FH70's documented role is indirect fire from the Saudi side of the border into northern Yemen. Arms Trade Watch describes Saudi artillery units positioned near the border as able to strike 40 km into Yemen and places the FH70 among the Saudi artillery systems active in that border-fire context.
The FH70 was not a newly supplied Yemen-war weapon in the public sources checked here; it was a Saudi Army 155 mm towed howitzer already present in Saudi inventories. A U.S. Marine Corps Intelligence Activity handbook lists the FH70 under Saudi 155 mm towed artillery and gives the system's crew, range, rate-of-fire, and auxiliary-power-unit characteristics, which are useful background for identifying the system but do not by themselves prove Yemen-war use.
