M7S Caseless Submachine Gun

"The suppressed M7 -- tears through armor and turns bad guys into chum."

- Gunnery Sergeant Edward Buck, giving a run-down of the M7S in the Desperate Measures Video Documentary.

The M7S Submachine Gun or the Suppressed SMG, is a United Nations Space Command infantry weapon.

Design Details
The M7S is a variant of the M7/Caseless Submachine Gun. Although the M7 is primarily issued to vehicle crews, the M7S is a favorite of commando teams. Sustained fire tends to cause the muzzle to “walk” upwards as recoil compounds. It is a good weapon for stealth and hit-and-run missions.

Changes from Standard M7

 * The M7S is equipped with a SS/M 49 sound suppressor.
 * The M7S is equipped with a muzzle flash suppressor.
 * The M7S is equipped with a reflex sight that uses a miniature reticule, making it more effective in dark areas and general close quarters combat.
 * Similar to the Shotgun, a flashlight is attached under the suppressor off to the bottom left side of the barrel, but it is not usable.
 * The magazine capacity has been reduced from 60 rounds to 48.
 * The M7S can be fired while zoomed-in. The smart-link scope displays the sight image on the user's HUD (not the reflex sight).
 * It is more accurate at long ranges.
 * It deals slightly less damage.

Miscellaneous

 * This is the signature weapon of the protagonist of Halo 3: ODST, the Rookie.
 * This is the starting weapon in most Halo 3: ODST Firefight levels except for Windward, where you start with a Sniper Rifle instead.
 * The Halo 3: ODST handbook states that the M7S is "a sound-suppressed variant of the M7 rifle." This could be a careless mistake, as submachine guns are not rifles. However, the handbook could be referring to the M7's rifled barrel.
 * The M7S is the first fully-automatic weapon in the Halo series to have a usable scope.
 * The M7S is the first scoped weapon that is not headshot-capable. The second is the Focus Rifle in Halo: Reach.
