Operation Trebuchet (OPTRE) is a fan-made total conversion mod for the military simulation FPS Arma 3. Developed by Article 2 Studios, the mod is an attempt to transplant the Halo universe into that of a more realistic military simulation. The mod is set during Operation: TREBUCHET, a massive-scale counterinsurgency operation conducted by the UNSC during the Insurrection. Players can play as UNSC Marines, UNSC Army, naval officers, SPARTAN-IIs and Insurrectionists.


OPTRE originally started as a different Arma 3 mod known as The Eridanus Insurrection, intended with the same goal of bringing Halo to a more realistic setting. In 2015, The Eridanus Insurrection ceased development and work on OPTRE began.[1].[2] Since 2015, the development team for OPTRE has created a multitude of assets from across the Halo universe.

In 2018, the mod was officially recognized by 343 Industries in a community update on Halo Waypoint.[1]
