The Sawed-Off Shotgun in Call of Duty: WW2 is a double barreled shotgun. The Sawed-Off Shotgun has low range but high damage output. You will want to be close to enemies, although you also need to be careful not to take on too many enemies at once due to only having two slugs between reloads. Maneuvering the map smartly and surprising enemies will be key to success. The best attachments for the Sawed-Off Shotgun are those that extend it’s range just a little bit further. The steady aim attachment reduces the spread of the pellets making it a little easier to kill enemies at range. The advanced rifling attachment for the Sawed-Off Shotgun reduces the damage fall off making it easier to secure kills at the edge of your range. The best division for the Sawed-Off Shotgun is expeditionary as it grants the incendiary ammo which helps increase the damage output of the Sawed-Off Shotgun.
The best basic training is hustle which lets you reload whilst running and reduces reload times. Pick your favorite secondary and use the mk 2 fragmentation grenade to attack clusters of enemies. Use the smoke grenade to screen your movement through open areas. Here is the complete best class setup for the Sawed-Off Shotgun..
