The Submachine Gun or SMG is an automatic weapon available in Wolfenstein: The New Order. It is the standard issued primary weapon of the Allied Forces against the Nazis in 1946. It is in fact the first weapon used by the player through the eyes of B.J. Blazkowicz while he and a small team go after Wilhelm Strasse. While ammo may get somewhat hard to find, its relatively low recoil, good rate of fire and medium power make it an excellent choice from close quarters to medium range combat. It is a retro-futuristic version of the Thompson 1928.
Notes
While very useful and ammo is fairly common, many players prefer the German Assault Rifle instead because of it's slightly higher power as well as ammo for such weapon is more common, not to mention to conserve ammunition for use with the suppressed Handgun 1946.
The SMG is akin to the MP40 and MP43 from the previous game, almost identical in terms of combat purpose, effective range, and recoil .
Before rappelling up Deathsheads fortress, Fergus admits that the submachine guns themselves are inferior to the German Assault rifles and tells everyone to pick one up off a dead nazi soldier if possible.
