The SVT-40 rifle in Call of Duty: WW2 is an extremely slow firing, high damage, long range rifle. The SVT-40 is best used in a defensive position behind cover. The prefer range is medium range, although long range is also possible. Short range is very difficult as a single missed shot can mean death. The best attachments for the SVT-40 are those that make firing whilst aiming down the sights more effective. The lens sight gives you clear visibility of enemies. The grip reduces the SVT-40’s high recoil making it easier to place the second shot for the kill. Use full metal jacket to increase the wall penetration of the SVT-40. The best division for the SVT-40 is infantry which grants you an extra attachment slot and gives you more starting ammunition, which is important as the SVT-40 quickly runs through its ammo supply. The best basic training is lookout which highlights enemies from further away letting you spot and kill enemies you didn’t even know where there. Use an automatic secondary to help you in close quarter areas where the SVT-40 is outclassed by other assault rifles and submachine guns. Use the mk 2 fragmentation grenade to clear tight spaces.
