Best Striker loadout and class build for Warzone and MW3

Get a blast from the past with the 2023 version of the classic UMP 45.

The Striker is an SMG available to use in Warzone and Modern Warfare 3 and from the MW3 era of weapons.

As is the case with Warzone and Modern Warfare 3's MCW, this weapon bears a strong resemblance to the UMP 45 from the original Modern Warfare 2 and 3, and is one of the reasons it's been a popular pick for many players.

On the whole, the Striker is a strong SMG that’s a brilliant choice for close-quarters, run-and-gun combat.

In this guide we’ll be running through how to unlock the Striker, as well as what are the best attachments, as well as the best Striker class build of vest, perks, and equipment.

Warzone and MW3 Striker best loadout and attachments

As an SMG, the Striker is typically most versatile at close ranges, but with our attachment recommendations, we’re going to be leaning into those strengths whilst boosting its viable range and accuracy.

Before running through them individually, here are the five attachments we’re picking for the Striker SMG in Warzone and Modern Warfare 3:

  • Optics: MK. 23 Reflector
  • Barrel: Striker Recon Long Barrel
  • Stock: FSS Priority Tactical Stock
  • Rear Grip: FTac G-5 Exo
  • Ammunition: .45 Auto High Grain Rounds

Whilst many may remember the Striker in its original 'UMP 45' form back in the original Modern Warfare 2 and 3, the gun feels a bit different here even if it's carrying its likeness.

For example, its iron sights are not as clear and focused as they were back then, making this variant more challenging to use without an Optic - whilst that’s still an option, we’re recommending you use the MK.23 Reflector, just to clean up your sights and make it easier to locate and hit targets.

Though of course you’re free to stick to the iron sights and opt for another attachment instead if you’re comfortable with the base iron sights.

Since we’re looking to give the Striker a boost at longer ranges, the Striker Recon Long Barrel is a great pick since it not only increases bullet velocity and range, but also improves gun kick control, aiming idle sway, and firing aim stability.

It does impede the spread of tac stance and hipfire attacks and slows aim walking speed by a small amount, but since we’re building into extending the weapon's range, it's perhaps a necessary trade off, though one to keep in mind if you’d prefer to go all in on a build for close-range encounters. Personally from my experience, I didn't notice much difference when building the gun this way.

As for the stock, it is somewhat of an interchangeable part depending on which playstyle you’d rather lean into.

For a more medium-range-focused build, the FSS Priority Tactical Stock is a great shout since it’ll give you greater accuracy thanks to Recoil Control and Aim Stability buffs, but it does negatively impact your mobility across ADS, movement, and aim-walking speed.

As an alternative - and to lean into a more mobile and agile playstyle - we’d recommend the Lachmann MK2 Light Stock as this will boost both your movement and sprint speed, and even if it has increased aiming idle sway and less gun kick control, you'll at least be a bit more mobile than the other option.

In terms of the fourth attachment, we’re picking the FTac G-5 Exo Rear Grip which is going to help keep you more accurate and on-target during gunfights thanks to its boosts to flinch resistance and aim stability.

The Lachmann MK2 Light Stock, an alternative stock choice for more mobility.

For the final attachment we're recommending for the Striker, it's the .45 Auto High Grain Rounds in the ammunition slot, which not only hide enemy skulls when you net kills, but also increases both bullet velocity and damage range. There's a hit to recoil control, but most encounters you'll likely end up in are within close-quarters proximity, so this should be less of a noticeable issue.

Warzone and MW3 Striker best class build, vest, perks, gear, and equipment

Since for this Striker loadout we’ve largely picked attachments that boost the weapon’s stability and medium range viability, for the gear and perks, we’ll be looking at options that improve mobility and speed to cater for a mobile playstyle.

As we'll be discussing how to build the best loadout for the Striker across both Warzone and MW3, there'll inherently be a different approach to how you build this class dependent on the game.

First we'll be discussing the Warzone aspects of this class, though be sure to scroll down a bit if you're looking for our Modern Warfare 3 Striker loadout recommendation.

Best Warzone Striker Loadout

  • Perk 1: Scavenger
  • Perk 2: Double Time
  • Perk 3: Stalker
  • Perk 4: Resolute
  • Secondary: Renetti w/ Jak Ferocity Carbine Aftermarket Part
  • Tactical: Flash Grenade
  • Lethal: Frag Grenade

As mentioned, we're looking at perks here that'll improve mobility and speed so as to cater for a mobile and faster-paced playstyle. With four perk slots there's a bit to consider.

The perk selection we're recommending for use with the Striker loadout in Warzone.

In terms of secondary and lethal/tactical equipment, this can often generally be down to personal preference - whilst we've listed our recommendations and discussed them below in our MW3 section, you might want to take something more suited to Warzone, whether that be C4 in the Lethal slot, or a Shock Stick in the Tactical slot, it's entirely up to you.

Back to the perks, we're kicking things off with the old faithful Scavenger which will help you keep stocked up on ammo, cash, and armour in Warzone matches.

Boosting the mobility here is being done across our three other recommended perks, each of which boost your speed and mobility in different ways. Whilst Double Time places an emphasis on improving Tac Sprint via duration and cooldown time buffs, Stalker is focused on improving strafe and ADS movement speeds. Topping it off as a bit of a defensive option, Resolute will net you a movement speed buff when taking gunfire damage, helping you run to safety quicker.

As for our approach to the Modern Warfare 3 version of this playstyle, there are a couple of extra factors to take into account and we discuss all that below. However, first let's have a high-level look at our overall recommendations for the Striker in Modern Warfare 3.

Best Modern Warfare 3 Striker Loadout

  • Vest: Infantry Vest
  • Perk 1 - Gloves: Scavenger Gloves
  • Perk 2 - Boots: Lightweight Boots
  • Perk 3 - Gear: Mission Control Comlink
  • Secondary Weapon: Renetti w/ Jak Ferocity Carbine Aftermarket Part
  • Field Upgrade: Munitions Box OR A.C.S.
  • Lethal: Frag Grenade
  • Tactical: Flash Grenade
The loadout build for the Striker SMG.

First up, the Infantry Vest is a large part of the core playstyle we’re building here.

Whilst you could pick the Gunner Vest to spawn with more ammo, as we’re picking the Scavenger Gloves that let you pick up ammo from defeated enemies, the Infantry Vest grants some mobility buffs from the outset thanks to an increased Tac Sprint duration and reduced refresh time, and the gloves will help you keep stocked up as you play.

To further increase the mobility of the class here, for the second perk, we’re recommending the Lightweight Boots, which increase both movement and swimming speed, as well as reduce the noise you make whilst swimming.

Ultimately, one of the main benefits here is the increased movement speed which helps offset the slowdown created by a couple of the Striker’s attachments.

As for the third perk - our recommended 'Gear' slot choice - we’re going with Mission Control Comlink, a fairly simple addition that makes the killstreak loop more rewarding at a quicker rate, reducing the number of kills you need to earn a streak by one, or 125 score if you’ve selected to earn streaks via score instead of kills.

For the secondary weapon, since the Striker - whilst still being great at close ranges – has been amped up a little to take on enemies at slightly farther away distances, we’re going with something intentionally designed for close range combat.

We’re taking the Renetti pistol, and equipping it with the Jak Ferocity Carbine Aftermarket Part that essentially turns the 3-round burst handgun into a full-auto, mini-SMG. You might want to throw on a mag size increase though, since it eats through ammo fast, and 15 in a mag doesn’t quite cut it.

Moving onto the equipment, when it comes to Field Upgrade, it’s generally up to you in terms of your preference.

For this class in particular, there are a couple of strong options. If you’re wanting to stay even more stocked up on ammo outside of what Scavenger is providing, the Munitions Box is a good shout.

However, if you want to focus on objectives as you move through the map, the A.C.S. is a strong choice since it’ll automatically capture objective points and temporarily hack nearby enemy devices too, which might be perfect for a more offensive, run-and-gun playstyle.

As for the Tactical and Lethal equipment slots, you can probably stick to Frag Grenade for the latter, but Battle Rage is a good shout for the Tactical slot since upon usage, it’ll regenerate your health quickly, tactical equipment affects are resisted, and your Tactical Sprint is constantly refreshed, capping off the mobility buffs of this class quite nicely.

As with all recommended loadouts, you might decide to tweak a few things to your liking as you play, and with so many attachments, perks, and equipment, there are many combinations to try to suit a class to your liking.

How to unlock the Striker in Warzone and MW3

To be able to get your hands on the Striker and use it in your own custom loadouts in Modern Warfare 3, you’ll have to reach player level 4.

To increase your player level, all you need to do is play Multiplayer matches, completing objectives, netting kills, and more, and you’ll earn XP which in turn, increases your player level.

Once at level 4, you can then equip the Striker into your loadout and begin to level it up and open up its attachment slots.

Keep in mind though that since attachments are unlocked universally across all weapons, whilst you’ll need to unlock the slots to equip attachments by levelling the Striker up itself, you might also want to use a mix of other weapons to open up more options for what’s available.
