The M150 155 mm hexachloroethane smoke projectile is documented in the 2023 Israel-Hamas War through open-source munition records from Gaza and image verification of Israeli artillery projectiles marked for Gaza. The Open Source Munitions Portal recorded a delivered, unfunctioned, whole 155 mm smoke artillery projectile in Gaza on 25 November 2023 and listed its tentative model as M150.
A second OSMP record from 11 December 2023 cataloged an undelivered, unfunctioned 155 mm smoke projectile in Gaza with the tentative model M150. Snopes later examined images of Israeli projectiles posted online, matched the markings to M150 smoke projectiles, and described the pictured rounds as Gaza-bound.

Timeline
The dated public record begins in late 2023. OSMP 520 records a 25 November 2023 Gaza entry for a delivered, unfunctioned, whole artillery projectile categorized as a 155 mm smoke munition and tentatively identified as M150.
On 11 December 2023, OSMP 513 recorded another Gaza 155 mm smoke projectile with M150 as the tentative model. In October 2024, ARES linked OSMP entries to a technical identification guide for the two common IDF 155 mm smoke projectile families, M825-series white-phosphorus rounds and the M150 HC smoke round. In August 2025, Snopes reviewed online projectile images and identified M150 markings on shells described as bound for Gaza.

Narrative
The available evidence places the M150 on the Israeli side of the conflict. The parent projectile is an Israeli Elbit Systems smoke munition, and ARES describes the M150 HC smoke round as one of two common 155 mm smoke projectile types in IDF service. The Snopes image review tied the pictured M150-marked projectiles to Israeli soldiers and Gaza-bound artillery ammunition, while OSMP records document M150-type smoke projectiles in Gaza itself.
The sources support a smoke and obscuration role rather than a specific casualty-producing or strike-assessment claim. ARES explains that the M150 carries five HC smoke canisters that are expelled from the projectile and burn to generate smoke, and OSMP classifies the Gaza entries as smoke munitions in the surface-to-surface artillery domain.
