M7S Caseless Submachine Gun

"Hell, we didn't even have to change magazines."

- Staff Sergeant Nolan Byrne, after clearing a room filled with rebels using the M7S.

The M7S Submachine Gun is a United Nations Space Command ground firearm.

It's also known as the Suppressed SMG, or M7S, and commonly called as the Silenced SMG.

Background
The M7S is a variant of the M7 Caseless Submachine Gun, which fires a M443 Caseless Full Metal Jacket style round. This variant features an external flash and sound suppressor on the barrel along with a laser sight. Muzzle flash is significantly decreased, and firing the weapon gives a barely noticeable sound, increasing stealth applications for the M7S Submachine Gun and increasing accuracy from decreased recoil making the weapon more efficient at medium-long range; however, power is decreased because of the slowing of projectile velocity from the suppressor. It is a good weapon for stealth and hit-and-run missions.

Appearances
This weapon can be seen on an example map included in the files of Halo 2 Vista's built-in map editor. The map is simply named "Example" and the map's description is "This is just a small example of what you can do as a Halo 2 cartographer!".

The suppressed M7 can also be found in the Halo Graphic Novel Armor Testing story, Halo: Contact Harvest and in Halo: First Strike where SPARTAN-117 carried two Suppressed SMGs but only used a BR55 Battle Rifle during Operation: FIRST STRIKE.

In Halo: Contact Harvest, Staff Sergeant Avery Johnson and his squad of Marines used suppressed M7's to take out a room in a bomb factory filled with Insurrectionists in the prologue of the book.

It also appeared in the hands of an Unnamed Marine Shock Trooper(The Rookie) in the Keep It Clean trailer for Halo 3: Recon, and also featured a red dot sight and a Laser Aiming Module.

Trivia

 * Not only is this SMG in Halo 2 Vista, but CMT (Custom Mapping Team) has recreated it for Halo Custom Edition. It generally resembles that of Halo 2 Vista, and has basically the same performance.
 * Since Halo 3: Recon will be a much stealthier game, it looks like the M7S will be the protagonist's best weapon of choice.
