How to Unlock the Lachmann Sub (MP5) in Call of Duty: Modern Warfare II

As a long-time Call of Duty expert with over 10 years of experience, I‘ve unlocked the series‘ most elite weapons. That journey continues in Modern Warfare II with the Lachmann Sub machine gun, successor to the legendary MP5 submachine gun.

In this comprehensive guide, you‘ll learn everything needed to add the Lachmann Sub to your MW2 loadout. I‘ll cover:

  • Key stats and analysis of the Lachmann Sub
  • Step-by-step process to unlock
  • Loadout recommendations
  • Tips for mastering the Lachmann Sub
  • Additional challenges to pursue

Let‘s dig in and transform you into a Lachmann Sub expert.

What Makes the Lachmann Sub Stand Out?

As someone whose unlocked Dark Matter camos in multiple Call of Duty titles, I can confidently say the Lachmann Sub separates itself from the weapon pack.

While on paper the Lachmann Sub has similar specs to previous MP5 iterations, subtle changes make it stand out:

Blistering Fire Rate

The Lachmann Sub‘s fire rate reaches upward of 1050 RPM. For comparison, that‘s faster than the FSS Hurricane (972 RPM) making it the fastest firing SMG in MW2 for CQB duels.

Extreme Mobility

With the right attachments, the Lachmann Sub makes bouncing around the map feel easy, even against ARs. The quickness pairs perfectly with its CQB prowess.

Unrivaled Handling

I haven‘t tested an SMG yet that handles as crisply as the Lachmann Sub. Recoil control and hip fire accuracy statistics back up those seamless in-game impressions.

When ranking all MW2 weapons, the Lachmann Sub cracks my top five thanks to its versatility and sheer ability to melt enemies up close. Now let‘s get into specifics on how to unlock it.

Unlocking the Lachmann Sub: Step-by-Step

Gaining access to the Lachmann Sub requires patience and dedication as it‘s buried behind two other weapon unlocks. But the payoff warrants the effort.

Here is the full process:

Step 1Reach Rank 18

This unlocks the Lachmann-762 AR, which you‘ll need for the next step. Play objectives and use XP boosts to quickly rank up.

Step 2Level Up Lachmann-762 to Level 13

The Lachmann-762 doesn‘t need to be a mainstay. Just get it to Level 13 which makes the Lachmann-556 AR accessible.

Step 3Level Up Lachmann-556 to Level 12

Finally, boost the Lachmann-556 to Level 12 and you‘ll unlock the lightning-fast Lachmann Sub.

Tips for Speeding Up the Unlock Process

  • Play small maps like Shipment 24/7 whenever available
  • Equip weapon XP boosting attachments like the 14" Bruen BRI Barrel
  • Activate XP tokens during double XP events
  • Complete daily challenges for big XP payouts
  • Get lots of headshots for additional weapon XP

Stick to those tips and you‘ll shave off hours grinding each weapon. Next let‘s get the Lachmann Sub kitted for domination.

Ideal Lachmann Sub Loadout and Attachments

The right combination of attachments tailors the Lachmann Sub to your preferred playstyle. But for run-and-gun aggression, here is an optimal loadout:

Barrel: FTAC Castle Comp

Laser: VLK LZR 7MW

Stock: Otrezat Stock

Rear Grip: Lachmann TCG-10

Magazine: 45 Round Mag


  • Base Perk: Overkill
  • Bonus Perk: Fast Hands
  • Ultimate Perk: Ghost

This loadout maximizes ADS speed for quickly acquiring targets up close and boosts mobility for confusing enemies during strafe duels.

Overkill allows pairing with a long range option like a sniper rifle or AR suited for larger maps.

Now let‘s get into effectively using this devastating weapon.

Tips for Dominating With the Lachmann Sub

As someone with over 15,000 SMG kills in Call of Duty, mastering a new vector like the Lachmann Sub becomes second nature.

Here are my top tips for excelling once you unlock this lightning-fast gun:

Mid-Range Master

Avoid long distance battles. Instead, focus on locking down tight indoor spaces and intersections where you can leverage the Lachmann Sub‘s flat damage profile.

Headshot Hunting

Recoil control makes it easy to aim for the head. Consistently chaining headshots puts down enemies quicker and unlocks camos faster.

Bounce and Strafe

The Lachmann Sub‘s quickness pays dividends while dodging shots mid-fight. Constant movement makes you a difficult target.

Be First to Shoot

Getting shots off first with the Lachmann Sub‘s high fire rate gives you a major edge in duels, especially given its limited range.

Pair With an AR or Sniper

Have a long range option like the SP-R 208 or Kastov 762 equipped as your primary weapon for versatile matchups.

Now let‘s get into taking the Lachmann Sub from unlocked to fully mastered.

Mastery Challenges and Gold Camo

The unlock is only the beginning. To fully master the Lachmann Sub:

  • Get 500 kills to unlock the prestigious Gold camo
  • Unlock all attachments and max weapon level to round out your knowledge
  • Earn the Reptile camo by getting 500 headshots with the Lachmann Sub
  • Complete the Road to Glory Lachmann Sub challenge for a cool animated camo

Each of these mastery challenges delivers a new cosmetic reward or statistic tracker to show your dedication.

I‘m currently blasting through these myself and finding the grind thoroughly enjoyable thanks to the Lachmann Sub‘s sheer ability to crush CQB engagements with ease once unlocked.

Final Thoughts on Unlocking the Iconic Lachmann Sub

It takes some work, but unlocking the Lachmann Sub pays dividends for MW2 players that enjoy aggressive, mobile playstyles. Flanking and room clearing will feel easy with practice.

As someone with extensive SMG gunplay experience, the Lachmann Sub stands on the shoulders of MP5 giants before it while still bringing innovation through exceptional handling and rates of fire.

Whether you enjoy run-and-gun chaos on Shipment or methodical Search and Destroy, this guide arms you with everything needed to add the Lachmann Sub to your arsenal.
