Here are the best Warzone Iron Trials loadouts to take down enemies in the competitive spin on the battle royale mode.

 This content is not currently available in-game following the discontinuation of support for the Black Ops Cold War version of Warzone. However, Iron Trials could return again in the future, so this guide will be updated and will be useful if so.

With a longer time-to-kill and increased player health, Warzone’s Iron Trials mode was really putting people’s gunplay to the test back in the Black Ops Cold War era. This competitive mode was designed to be an evolution from the standard battle royale so, naturally, it meant you had to adapt.

It certainly shook up the Warzone meta at the time as some of the best Warzone guns were failing to cut it in this skilled arena – forcing players to think more creatively about their Iron Trials loadouts. Sniper rifles were out, unless you could use them accurately in close-quarters combat, and guns with a high fire rate and high damage rate were in.

While it’s not currently available in Warzone, it is possible that the Iron Trials will return so it’s a good idea to have an understanding of the best Warzone Iron Trials loadouts just in case. Although it debuted in Call of Duty Black Ops Cold War’s version of the battle royale game, it did return in Call of Duty Vanguard. However, it has not been seen since.

Best Warzone Iron Trials loadouts

The best Iron Trial loadouts were: 

  • Stoner 63 & Bullfrog
  • Krig 6 & Akimbo Sykov
  • XM4 & PPSH
  • MG82 & Milano

The Stoner 63 was probably the best LMG in the game at the time as it boasted an incredible damage rate, even at range. The increased magazine capacity was a plus, given the mode’s longer TTK, as was the gun’s fire rate. Check out our Stoner 63 loadout below for more details on how we set it up.

  • Agency Suppressor
  • 21.8” Task Force
  • Royal & Kross 4x Optic
  • Field Agent Grip
  • Airborne Elastic Wrap

When set up correctly, the Bullfrog was an absolute beast in close quarters, making it the perfect secondary. The right attachments, all of which were listed in our Bullfrog Warzone loadout, helped keep the gun stable when you were blasting through a mag.

  • Gru Suppressor
  • 7.4″ Task Force
  • Gru 5mW Laser
  • Spetsnaz PKM Stock
  • 65 Rnd Speed Mag

In short, this was a brilliant Iron Trials loadout for long-range, especially if you preferred to loot in open areas.

Krig 6 and Akimbo Sykov Iron Trials loadout

The Krig 6 was one of the best assault rifles during the Black Ops Cold War era, helped by its controllable recoil pattern and high damage rate. This Krig 6 Warzone loadout below, which was tailored for Iron Trials, was designed to damage your opponents as much as possible. It was not as mobile as standard Warzone builds were, but the attachments made up for that in multiple other ways.

  • Agency Suppressor
  • 15” CMV Mil-Spec barrel
  • SUSAT Multizoom
  • Field Agent Grip
  • STANAG 60 Rnd Mag

If you were an aggressive player who wanted to use a perk like Ghost, you couldn’t go wrong with picking the Akimbo Sykovs as your pistol choice. These fully-automatic pistols were deadly up close, and, given the fact they both packed 80-round drum mags, you had a whole lot of ammo at your disposal.

  • Monolithic Suppressor
  • Sorokin 140mm Auto
  • 5mW laser
  • 80-Round Drums

This was a great option for a second loadout if you wanted to switch to Ghost from Overkill. It was also a good option if you preferred to keep things simple with a well-balanced setup.

XM4 and PPSH Iron Trials loadout

The XM4 was one of the best assault rifles for Iron Trials, next to the Krig 6. This setup was a bit different from our normal XM4 Warzone loadout and that was because it prioritized accuracy, damage, and range at the cost of mobility to counter the increased health of opponents. Here’s how we set it up:

  • Agency Suppressor
  • 13.5” Task Force
  • Axial Arms 3x
  • Field Agent Grip
  • STANAG 60 Rnd

The PPSH was one of the best weapons in Iron Trials to put a dent in your opponent’s health. It was also an SMG with good mobility, making it easy for you to zip in and out of buildings in pursuit of enemies. Here’s how we set it up:

  • Gru Suppressor
  • Tiger Team Spotlight
  • Quickdot LED
  • Bruiser Grip
  • 71 Rnd Drum

This was an interesting loadout that you probably wouldn’t have used in regular Warzone lobbies, but the two guns perfectly complemented each other and packed the perfect punch for Iron Trials.

MG 82 and Milano Iron Trials loadout

The MG 82 had one of the biggest magazine sizes in the game, so naturally, it made its way onto our best Iron Trials loadout list. Since it had a good default mag size, this loadout focused on increasing its accuracy, damage, range, and control, making it a beast at long and mid-range.

  • Agency Suppressor
  • 16.4” Task Force
  • Axial Arms 3x
  • Field Agent Grip
  • Serpent Wrap

The Milano dominated the Warzone meta for a long time and it did the same in Iron Trials. With a high damage and fire rate, this nifty little SMG – which boosted your mobility stats – was a decent secondary for those tight encounters. It was similar to our best Milano Warzone loadout, which you can see below:

  • Agency Suppressor
  • 10.6” Task Force
  • Tiger Team Spotlight
  • Raider Stock
  • STANAG 55 Rnd Drum

This loadout combined the biggest and smallest weapons in the games for a neat little package that ensured you could take fights at all ranges.

Best Warzone Iron Trials perks and equipment

Since Iron Trials tweaked the standard battle royale ruleset and increased the time to kill, you wanted to reconsider what perks and equipment you took into battle.

For your Iron Trial Perks, we recommended Quick Fix, Overkill, and Amped, since Quick Fix helped you regenerate health after killing an enemy and Amped increased your weapon swap speed. Overkill was the best second perk here as it allowed you to get creative with your loadout, but a second loadout with Ghost was a good thing to have at the ready.

For your Iron Trials equipment, it wasn’t as prescriptive. Stuns, Heartbeat Sensors, and Stims were all good options, but given health regeneration speed was slashed, we recommended carrying Stims.

In the lethal department, Thermites were your best bet as they output a large amount of damage and lasted longer than most options – a great way to deal with the increased health in Iron Trials.

There you have it, the rundown of the best Warzone Iron Trials loadouts out there. With the opportunity to experiment with more unique loadouts and builds compared to the standard battle royale mode, it’s a shame that Iron Trials is no more – though it could one day return.
