The M41 Rocket Launcher, alternatively called the "Spanker" or "Jackhammer", is a heavy ordinance weapon of the UNSC arsenal. The M41 sports a 2x scope and can fire rockets over long distances with devestating accuracy.

NOTE: The most critical gameplay question here goes unanswered; will the rocket launcher in H3 "lock on" to significant targets like vehicles and turrets, as it did in Halo 2? Or will it lose this ability and return to its state in Halo 1? As it has the same appearance and designation (M41) as Halo 2's rocket launcher, one might be led to assume the features are the same.

UPDATE: In the Public Beta, the rocket launcher behaves as it does in Halo 1; it does not "lock on" to enemy vehicles or turrets.
