The Type 100 submachine gun in Call of Duty: WW2 is a versatile machine gun that is strong at medium and close range, although it is disadvantaged to some submachine guns at close range. It is accurate and has good range. Aiming down the sights of the Type 100 makes it easier to kill enemies due to the low fire rate which makes hip fire weaker. You will want to be close to enemies, preferably where they don’t expect you to be. You will also need to be able to reload quickly to dispatch enemies in quick succession. The quickdraw attachment to the Type 100 lets you aim down the sights faster, which means you can take advantage of the Type 100’s accuracy even when you are surprised by enemies.

To reduce the recoil whilst aiming down the sights use the grip attachment. The best division for the Type 100 is airborne as it lets you move faster and reload more quickly helping you get close to enemies. The best basic training is lookout which helps you spot enemies when they are further away. This helps especially when you aim down the sights of the Type 100. Use your favorite secondary in case you run out of ammo and use the smoke grenade to help you move through open areas. You can also throw the smoke grenade at entrenched enemies to make their position much less advantageous.
