The M79 Osa is a Yugoslav-designed, reusable 90 mm shoulder-fired anti-tank rocket launcher built around unguided HEAT rockets, a detachable rocket container, and optical sighting. In Islamic State inventories it provided a portable direct-fire anti-armor and fortification weapon, with documented M79 rockets captured from IS forces in Syria and reporting that M79 launchers reached Iraq during the 2013-2017 war.
Conflict Armament Research documented M79 Osa 90 mm HEAT rockets captured from Islamic State forces by the YPG near Ras al-Ayn, Syria, in 2014, indicating Islamic State fielding of the weapon during the wider anti-ISIS campaign.
CTC Sentinel described M79 Osa launchers among light anti-tank weapons reaching Iraq for Islamic State use, supporting a narrow Iraq-specific fielding claim rather than a confirmed individual firing incident.
