Direct proof of use
The Open Source Munitions Portal's OSMP 636 record, dated 19 December 2023, identifies an Israeli 120 mm tank-gun round as an APFSDS-T kinetic munition whose physical features match either the M322 or M338. The same record places the item in Israel, lists it under tank-gun projectiles, and records it as an unguided surface-to-surface munition.
The source does not document an impact or a specific tank engagement. OSMP lists the item as whole, undelivered, and unfunctioned, so the supported conflict claim is a documented Israeli M322-or-M338 identification in the Israel and Gaza 2023-2026 collection, not confirmed firing in Gaza.

Timeline
OSMP's record date provides the clearest dated milestone for this conflict-specific identification. Its wider Israel and Gaza collection covers images from Israel and the Gaza Strip from October 2023 and includes munitions allegedly deployed by Israeli forces and Palestinian armed groups.
Manufacturer material from Elbit Systems gives the technical context for the identification: both M322 and M338 are 120 mm APFSDS-T cartridges for NATO 120 mm L44/L55 smoothbore tank guns, and Elbit lists Merkava 3 and Merkava 4 among the 120 mm series' compatible firing platforms.

Role and evidence limits
M322 and M338 are kinetic anti-armor tank cartridges rather than explosive projectiles. Elbit describes M322 as a second-generation APFSDS-T round with a tungsten-alloy penetrator and M338 as a third-generation APFSDS-T round with low-vulnerability propellant, both intended for 120 mm smoothbore tank guns.
For this conflict page, the role is therefore recorded as Israeli anti-armor tank ammunition identification. The public OSMP entry supports the designation family and conflict collection context, but it does not identify a firing unit, target, impact site, or operational result.
