M41 SPNKr

The M41 Surface-to-Surface Rocket Medium Anti-Vehicle / Assault Weapon, or M41 SSR MAAW, is a heavy ordnance weapon used by the UNSC Defense Force. It is manufactured by Misriah Armory. Formally known as the Medium Anti-Vehicle / Assault Weapon, Bore 102mm, M41 Surface-to-Surface Rocket Launcher. Nicknamed the Jackhammer or the SPNKR.

Design details
Through the various shoulder-launched rocket launchers used by the UNSC Defense Force since its creation, only the M41 rocket launcher has the tactical importance to be heavily manufactured. The M41 SSR has been in service with the UNSCDF for decades, as early as the Insurrection. It fires M19 102mm high-explosive shaped charge missiles. The weapon uses a unique system for loading and firing: rather than using a traditional magazine or single-shot system, it is fed by a pair of detachable barrels, each of which holds a single rocket. When one of the rockets is fired, the other is cycled into place; when both have been fired, the operator removes the barrel unit and inserts another. This allows the operator to quickly reload while in combat and greatly reduces the weight he carries without throwing the weapon away, as with some disposable rocket launchers of the twentieth and twenty-first centuries.

The launcher has a 2x scope and can fire rockets over long distances with devastating accuracy, although the rockets' altitude decreases over long distances. The weapon possesses great firepower and, in many cases, is able to destroy even a Covenant Wraith tank with a single missile. Infantry armed with M41 rocket launchers can often turn the tide of a battle after other sources of heavy firepower have been destroyed. Many M41s and their M19 rockets are equipped with target tracking systems; these systems allow the operator to "home" on a target, which often guarantees that the target will be struck, even if it attempts evasive maneuvers. Some launchers are capable of tracking both ground-based and airborne targets, while others are capable of tracking only aircraft. Some M41s lack any form of tracking technology, requiring the operator to "dumb fire" the weapon without targeting assistance.

Some M41s feature a smart-linked sight, a trigger guard, and an ergonomic thumbhole stock, adding the impression of greater bulk. However, other versions lack these design features, possessing only a pistol grip and no trigger guard, resulting in a more skeletal overall appearance.

Trivia

 * The weapon was identified as the M19 SSM rocket launcher in the game manuals of Halo: Combat Evolved and Halo 2 as well as in the Art of Halo 3. It was also referred to in Halo: Ghosts of Onyx as the M19 missile launcher. It was established in Halo: The Essential Visual Guide that M19 SSM refers to the rocket ammunition while the launcher itself is designated as the M41.
 * The M41 SSR is aesthetically similar to the SPNKR-XP surface-to-surface missile launcher from Marathon 2 and Marathon Infinity. This weapon is also the source of the M41's "SPNKr" moniker.
 * On the last level of Halo 3: ODST there are four rocket launchers with 1000 rockets each for use in Vidmaster Challenge: Deja Vu. These only appear on the Legendary difficulty when the Iron Skull is activated. If any player boards a Warthog, these rocket launchers will not spawn.
 * If the player uses Emile-A239's voice in Firefight, he will occasionally say "Someone's gonna pay!" when he readies a rocket launcher. This is a reference to the level If I Had a Rocket Launcher, I'd Make Someone Pay from Marathon 2: Durandal, which, in turn, was named after the Bruce Cockburn song If I Had a Rocket Launcher.
