If you’re looking for the best SMG in Warzone Season 3 Reloaded, then you’ve come to the right place. We’ve ranked every SMG from worst to best and even picked out the best loadout class for each to give you an edge.

The best SMGs in Warzone can give you a huge advantage in close-quarter firefights, especially when you kit them out with meta attachments. While SMGs may not offer the range or accuracy of the game’s deadly Assault Rifles, they do give players the tools needed to get plenty of kills.

This hyper-aggressive playstyle may not be for every player, but having an SMG you can rely on in Warzone Season 3 Reloaded is incredibly important. Unlike the AR class, the SMG category is not that varied, and many players often gravitate towards only a couple of picks.


Of course, that hasn’t stopped certain loadouts from cropping up. To help you increase your win rate in Warzone Season 3 Reloaded, we’ve ranked all the best Warzone SMGs and the attachments you should be using with them.
