Direct proof of use
The Type 86P hand grenade is documented in the 2003 Iraq War through U.S. military reporting on weapons-cache discoveries west of Habbaniyah. A DVIDS republication of an American Forces Press Service story, compiled from Multinational Corps Iraq releases, reported that Marine engineers found four Type 86P grenades in a set of large caches during Operation River Sweep on January 1, 2007.
The report describes the caches as part of a combined hunt by engineers attached to 3rd Battalion, 2nd Marine Regiment, Regimental Combat Team 5, operating with elements of the 1st Iraqi Army Division and 3/2. It says the cache hunt was intended to interrupt insurgent activity, and that the Marines destroyed the caches after recovery.

Timeline
On January 1, 2007, Marine engineers uncovered twelve large caches west of Habbaniyah during Operation River Sweep. The Type 86P grenades were listed among mines, rockets, mortars, artillery projectiles, bombs, small-arms ammunition, warheads, and other munitions found in those caches.
The American Forces Press Service story was dated January 3, 2007. DVIDS later republished the archive story with the same account and public-domain status.

Narrative
The documented Iraq-war role for the Type 86P is recovered insurgent-cache materiel rather than a confirmed individual grenade attack. The source does not identify a named insurgent group, transfer chain, original stockpile owner, or a specific casualty-producing incident involving the grenade.
Within the recovered cache list, the Type 86P appears as a close-combat fragmentation munition alongside a much larger set of explosives and indirect-fire munitions. The U.S. report tied the overall cache set to insurgent attack capability, including IEDs, indirect fire, and small-arms engagements, but it did not state how the four Type 86P grenades had been acquired or whether they had already been issued to a particular cell.
Technical identification is consistent with the parent Type 86P profile: a U.S. ordnance identification guide describes the Type 86P as a Chinese fragmentation hand grenade with a plastic body, striker-release delay fuze, and steel-ball fragmentation liner. Those technical details support identification context only; the Iraq conflict-use claim rests on the DVIDS/Multinational Corps Iraq cache report.
