A submachine gun in Call of Duty: Warzone is only as good as its attachments and perks in the loadout you choose.

In general, SMG’s in Warzone usually need to be paired up with a long-range option in an Overkill class. The best way to ensure success in the game is to use a powerful SMG for close-quarters fights and an assault rifle, LMG, sniper rifle, or other long-range option for fights at a distance.

SMG’s should be used to navigate close-quarters environments, and players should also get in the habit of swapping to the SMG in their loadout when trying to move as fast as possible in between cover. SMG’s are dominant on the game’s smaller maps, like Fortune’s Keep and Rebirth Island, and should be leveled up to keep up with the crowd.

Here are some of the best current SMG loadouts to use in Warzone.
