Direct proof of use
Oryx's November 2014 visual inventory of Islamic State equipment in Syria listed 11 122 mm BM-21 launchers under multiple rocket launchers. The same entry identified one 122 mm launcher mounted on a Navistar International 7000-series truck as captured in Iraq, showing the cross-border movement of captured heavy equipment within the Iraq-Syria campaign.
Coalition imagery later documented BM-21 use by anti-ISIS partner forces. A DVIDS record from Combined Joint Task Force - Operation Inherent Resolve shows Iraqi Security Forces firing a BM-21 Grad near Rawa, Iraq, on November 17, 2017, with the caption stating that the strikes were part of the global coalition campaign to defeat ISIS in Iraq and Syria.

Timeline
The strongest early evidence is a captured-equipment record rather than a dated fire mission: Oryx published its Syria list on November 10, 2014, during the period when ISIS held territory in both Iraq and Syria and moved captured materiel between fronts.
On November 17, 2017, Iraqi Security Forces used BM-21 Grad rockets near Rawa during the late western Iraq phase of the campaign. A U.S. Army Center for Army Lessons Learned interview package later captioned the same Rawa fire mission as targeting ISIS fighters during Iraqi-led operations to liberate Iraq from ISIS.

Narrative
The BM-21 Grad's role in this conflict was conventional unguided rocket artillery, but the evidence splits into two different patterns. On the Islamic State side, the launcher appears as captured heavy equipment in open-source visual inventories; Oryx treated the recorded count as a minimum because its lists included only vehicles and equipment with photo or video evidence.
On the anti-ISIS side, the Rawa imagery shows Iraqi Security Forces using BM-21s in an organized fire-support role under the wider Operation Inherent Resolve campaign. The public record does not make the BM-21 a coalition-supplied system in this case; it documents Iraqi forces employing the launcher during Iraqi-led operations against ISIS.
