Direct proof of use
Trophy is directly documented in the 2023 Israel-Hamas War on Israeli Merkava tanks operating in Gaza. On December 13, 2023, The War Zone reported on Hamas-released footage from fighting in and around Khan Younis that showed a Merkava under attack and its Trophy active-protection system triggering while the tank continued moving.
The same report treated the video as evidence of Trophy's battlefield role in Gaza urban fighting, while noting that the footage did not clearly identify the weapon fired at the tank and that a second clip involving a stationary Merkava was less clear.

Timeline
On October 26, 2023, as Israeli forces prepared and began limited armored activity ahead of a wider Gaza ground entrance, Defense News described Trophy as installed on Israel's Merkava IV tanks and expected to play a role against anti-tank weapons as ground forces advanced.
By mid-December 2023, public battlefield footage had moved the record from expected use to documented use: The War Zone identified Trophy activation on a Merkava in Hamas footage said to come from recent fighting around Khan Younis.

Narrative
Trophy's role in this conflict was defensive force protection for Israeli armor. Rafael describes the system as a hard-kill active-protection system for tanks, APCs, and other armored vehicles, with 360-degree azimuth protection and engagement of anti-tank guided missiles, RPGs, recoilless-rifle projectiles, HEAT tank rounds, and related chemical-energy threats.
That role mapped directly onto Gaza's urban anti-armor threat environment. Defense News reported before the wider ground campaign that Trophy was installed on Merkava IV tanks and expected to help disable anti-tank weapons as Israeli forces advanced into Gaza. The later Khan Younis footage analyzed by The War Zone showed the system in the kind of close urban engagement where armored vehicles faced attacks from covered firing points.
The documented user in the conflict is Israel. The available public evidence supports Trophy being fielded and activated on Merkava tanks in Gaza, but it does not establish a complete count of activations, the number of Trophy-equipped vehicles in the theater, or the result of every engagement involving Israeli tanks.
