Direct proof of use
The RPG-7's documented Yemen Civil War use is supported through battlefield munition evidence rather than a counted launcher inventory. Armament Research Services analyzed a November 21, 2016 Houthi-linked Al Masirah video from the Midi district fighting in Hajja Governorate and identified two types of RPG-7 shoulder-fired recoilless weapon projectiles in the displayed munitions: PG-7M-pattern rounds and Iranian PG-7-AT Nader rounds.
ARES assessed that the Nader projectiles had not been documented in service with Saudi-backed forces in Yemen, while Nader rounds had been documented in Houthi service. The source also treated the pictured Nader projectiles as most likely originating with pro-Saleh forces, while noting that battlefield capture could not be ruled out.

Timeline
The cited public incident record centers on late 2016. ARES placed the underlying fighting in the broader early-2016 battle for Hajja Governorate's Midi district, where Yemeni government forces based around Aden were fighting Houthi militants and forces loyal to former president Ali Abdullah Saleh.
On November 21, 2016, the Houthi-linked Al Masirah TV YouTube channel uploaded footage of arms and munitions allegedly captured in Midi. ARES used still imagery from that video to identify the RPG-7-compatible PG-7M-pattern and PG-7-AT Nader projectiles.

Narrative
In Yemen, the RPG-7 appears in the public record as a common shoulder-fired anti-armor and assault-support system whose specific documented evidence often comes from rounds, remnants, and captured munitions. The ARES example connects RPG-7-compatible ammunition to Houthi-aligned and pro-Saleh forces during the northern front around Midi, rather than to a named firing event, target, or casualty incident.
The PG-7-AT Nader is an Iranian RPG-7 projectile also known as Fath in some Iranian sources. ARES described the Nader's rounded projectile form and fuze arrangement as distinctive, and reported that examples of the PG-7-AT and its derivatives had appeared in several other theaters. For Yemen, the relevant claim is narrower: Nader projectiles were documented with Houthi forces and appeared in the Hajja Governorate material analyzed from the 2016 video.
The public source reviewed here does not establish how many RPG-7 launchers or projectiles Houthi-aligned forces held, whether the rounds came through a recent Iranian delivery, or whether any particular projectile was fired in the Midi fighting. It does support Houthi-aligned fielding of RPG-7-compatible projectiles during the 2014 Yemen Civil War.
