Direct proof of use
The Type 63 107 mm multiple rocket launcher appears in the 2014 Yemen Civil War record through Oryx's Houthi missile, rocket, and drone inventory. In the multiple-rocket-launcher section, Oryx lists a 107 mm Type 63 among Houthi-held systems and identifies it as inherited from pre-war Yemeni Army stocks.
That evidence supports Houthi-aligned possession or fielding of the launcher during the war. The cited public sources do not identify a separate dated Type 63 firing incident, target, battlefield location, or operator unit.

Timeline
Oryx's pre-war Yemeni fighting-vehicle inventory listed 107 mm Type 63 multiple rocket launchers in the Yemeni Army inventory before the Houthi takeover and the wider war, with a note that the launcher had not yet been seen in original configuration.
The later Houthi inventory then listed the 107 mm Type 63 among Houthi-held multiple rocket launchers in the continuing conflict. The documented pathway is inherited stock rather than a newly sourced wartime transfer.

Operational context
The Type 63 is a light 12-tube launcher for 107 mm unguided rockets. Weaponsystems.net describes the system as a short-range launcher that fires its twelve rockets in seconds, while FAS describes Type 63-family launchers and electrically initiated 107 mm high-explosive fragmentation rockets as part of the same weapon family.
In Yemen, the supported record is strongest for inventory and custody. The launcher should be read as part of the wider Houthi-aligned stock of inherited unguided rocket artillery, not as a separately documented precision or long-range strike system.
