M57 Pilum

This rocket launcher was used by the UNSC Army, UNSC Marine Corps, and Spartan (branch) around October, 2558. It performs very similarly to the M41 rocket launcher.

Design details
Despite performing much the same as the M41, the unidentified rocket launcher is significantly different in design philosophy, featuring a single, reusable, fixed tube and detachable box magazines rather than dual, rotating, pre-loaded, disposable tubes.

The weapon is fed by a two-round detachable box magazine on the upper left side, forward of the user. The magazine retracts into the weapon when chambering each round, similar to the Type-33 fuel rod gun. A 2x magnification scope folds out from a module on the left side when activated. Its missiles are able to lock onto aircraft if the operator uses smart scope.

Ad Victorium
The Ad Victorium fires three laser-guided missiles in a "V" formation. All three missiles feature an airburst proximity fuse. The operator must use smart scope in order to guide the missiles however.

High Five
The High Five fires five Hydra MLRS mini-missiles that will lock onto both ground and air targets. Unlike the base model and the Ad Victorum smart scope is not needed for the missiles to lock onto targets.
