Best Warzone SMG loadouts & Submachine Gun classes (Season 3 Reloaded)

The best Warzone SMG loadouts can be difficult to find, especially with there being so many options due to MW2 & MW3's arsenals being combined. However, identifying a top-tier Submachine Gun is absolutely essential, as the category is best-in-class at close quarters and perfect for aggressive outplays on Rebirth Island and Urzikstan.

So, in order to pick the best SMG in the Warzone Season 3 Reloaded patch that will dominate your opponents, I've compiled a ranked list of the strongest guns in the category.

Best Warzone 2 SMGs ranked

5. HRM-9

Best HRM-9 loadout

• Muzzle: ZEHMN35 Compensated Flash Hider
• Barrel: Princeps Long
• Stock: Folding Stock
• Ammunition: 9MM High Grain Rounds
• Magazine: 50 Round Drum

Hefty nerfs to the HRM-9 on May 9 have sent this weapon spiralling down the tier list, but it still manages to hold onto number five.

Its max damage output and range both took a hit, meaning it's no longer the premium choice, but it still offers a solid TTK, mobility, and snappy ADS time.

The HRM-9's time in the spotlight is definitely over, but if you're extremely comfortable with the gun, you can make it work.

4. AMR9

Best AMR9 loadout

• Barrel: Tectonic Micro Integrator Suppressor
• Optic: JAK Glassless Optic
• Magazine: 50 Round Drum
• Rear Grip: SAKIN ZX Grip
• Stock: DEMO D50 Buffer Tube

At MW3's release, the AMR9 was largely considered to be one of the worst options in the arsenal, but that changed massively when Sledgehammer decided to give it some much-needed buffs.

Unlike a lot of its competitors, the AMR9 can hold its own at mid-range.

This is important as that is brilliant for any tactical competitors who prefer to take on gunfights a little slower than ultra-aggressive players. So, if you want a little more versatility in your skirmishes, this could be the option for you.

3. RAM-9

Best RAM-9 loadout

• Muzzle: ZEHMN35 Compensated Flash Hider
• Barrel: Speedway V5 Short Barrel
• Comb: Recon Comb
• Underbarrel: DR-6 Handstop
• Magazine: 50 Round Mag

The RAM-9 has a blistering time-to-kill that sends enemies to the Gulag in milliseconds and paired with a meta AR like the SVA 545, you'll have the ultimate SMG loadout.

With the setup above, you'll have a hard-hitting SMG that's packed with mobility and plenty of rounds to finish off multiple opponents. I highly recommend this on Rebirth Island, as it's carried me to many high-kill games in Season 3.

2. WSP-9

Best WSP-9 loadout

• Muzzle: ZEHMN35 Compensated Flash Hider
• Barrel: HISS Short Light
• Optic: JAK Glassless Optic
• Underbarrel: DR-6 Handstop
• Magazine: 50 Round Mag

Coming in at number two is the deadly WSP-9, a weapon that's risen up through the ranks due to hefty nerfs to its competition and a sprint-to-fire time decrease making it far more aggressive. The powerful SMG features a slow rate of fire which can be unforgiving in certain gunfights, but if you hit your shots, it deletes foes.

Packed with plenty of stability and enough movement speed to traverse the largest of maps, this weapon has a lot to offer. Its strength has only increased since the release of the JAK Glassless Optic, which makes the gun deadly accurate.

1. Striker 9

Best Striker 9 loadout

• Muzzle: ZEHMN35 Compensated Flash Hider
• Barrel: Striker Elite Long Barrel
• Underbarrel: DR-6 Handstop
• Ammunition: 9MM High Grain Rounds
• Magazine: 50 Round Drum

A classic SMG modelled on the brilliant UMP45 from MW2 (2009), this weapon will feel instantly familiar to any OG Call of Duty competitors.

Similar to the AMR9 above, the Striker 9 can hold its own at medium-range as well as close-quarters, making it immensely versatile. This is thanks to the Striker Elite Long barrel that increases its damage range and bullet velocity.

If you want an SMG that's hard-hitting and won't falter if an opponent pops a little further away than expected, this loadout has to be your choice in MW3. If that wasn't enough to convince you, this powerhouse has a 9.5% pick rate according to WZStats, so it's a safe bet.
