M7S SMG

"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 falsely known 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; however, power is decreased because of the slowing of projectile velocity from the suppressor.

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, 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 rebels in the prologue of the book.

It also appeared in the hands of an Unnamed Marine Shock Trooper in the trailer for Halo 3: Recon, and also featured a red dot sight and a laser 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.
