Direct proof of use
Deutsche Welle reported that a January 2016 al-Qaida video from Yemen showed fighters with several German-designed weapons, including the G36 assault rifle, produced under Heckler & Koch license in Saudi Arabia. DW attributed the finding to an investigation it commissioned from Arab Reporters for Investigative Journalism.
The Bonn International Centre for Conflict Studies also identified the G36 in the Yemen war, reporting that the Saudi-licensed rifle was being used by various Yemeni groups and that captured G36 rifles had appeared with Houthi forces.

Timeline
BICC traced the relevant supply channel to a 2008 German approval for Saudi Arabia to produce the G36 under license, while noting that the license terms restricted the rifles to Saudi Army equipment.
In January 2016, according to DW, AQAP footage from Yemen showed G36 rifles among other German-designed small arms. DW reported that the weapons were first issued to units fighting for President Abed Rabbo Mansur Hadi and could then be sold or diverted through Yemen's wartime arms market.
By 2019, BICC described the G36 as a weapon used by various Yemeni groups and reported captured G36 rifles with Houthi forces, placing the rifle beyond a single confirmed AQAP appearance.

Role in the conflict
The sourced record points to small-unit rifle use rather than a centrally declared transfer to a single Yemeni force. DW described the route as initial issue to Hadi-aligned units, followed by sale or diversion to AQAP or other militant groups in a fragmented battlefield economy.
BICC's account broadens that picture: it reports G36 rifles among various Yemeni groups, eyewitness accounts of use by Sudanese soldiers fighting alongside Saudi Arabia, and captured rifles with Houthi forces. Those claims support both coalition-aligned supply context and later battlefield diffusion.

Conflict context
The Yemen conflict began in 2014 with Houthi advances against the internationally recognized government, followed by the Saudi-led coalition intervention in March 2015. AQAP remained a separate armed actor in the south and east, which shaped the environment in which coalition-supplied and locally traded weapons could move across factional lines.
