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

This comprehensive guide will walk you through exactly how to unlock the lightning fast Lachmann Sub SMG in Modern Warfare 2 Multiplayer.

Unlocking new weapons like the Lachmann Sub allows you to expand your arsenal and tailor loadouts to different playstyles and maps. Let‘s get into how to add this deadly CQB shredder to your MW2 weapon selection.

Introducing the Lachmann Sub

Longtime fans of Call of Duty will immediately recognize the Lachmann Sub as the MP5 submachine gun from earlier titles in the series. Despite the new moniker, the SMG returns in MW2 as an absolute close quarters monster.

The in-game description reads:

"The Lachmann‘s Sub fully compact, fully automatic, 9mm receiver is a masterpiece of stability, mobility, and lethality. The modular system is configurable for a variety of covert and close-quarters operations."

Living up to this description, the Lachmann Sub provides the fastest time-to-kill of any SMG at close range. It achieves this through a combination of high fire rate, modest damage, and extremely controllable recoil.

Here‘s a quick rundown of the Lachmann Sub‘s stats compared to other MW2 SMGs:

Weapon	Fire Rate	Damage	Recoil	Range
Lachmann Sub	98	35	Low	Short
FSS Hurricane	93	42	Low	Short
Vel 46	90	40	Medium	Medium
Basilisk	112	34	High	Very Short

With damage and fire rate tuned for CQB dominance, the Lachmann Sub excels in close engagements where its high bullet output melts opponents.

While other SMGs have some advantages in damage or range, none match the raw TTK speed of a kitted Lachmann Sub within 12 meters. It is simply the most lethal SMG in close quarters combat when unlocked.

Now let‘s get into how to add the Lachmann Sub to your SMG arsenal in MW2 Multiplayer.

Unlocking the Lachmann Sub in Modern Warfare 2

Unlocking new weapons in Modern Warfare 2 requires an investment of time and effort. The Lachmann Sub in particular is buried behind some prerequisites.

Here‘s an overview of the unlock path:

Reach Rank 18 to unlock the Lachmann-762 AR.
Level the Lachmann-762 to Rank 13 to unlock the Lachmann-556 AR.
Level the Lachmann-556 to Rank 12 to unlock the Lachmann Sub.

Let‘s break down how to efficiently complete each step.

Step 1: Grind to Rank 18 for the Lachmann-762

Reaching Rank 18 requires accumulating 18,000 XP. XP is primarily earned by completing matches and earning kills/objectives.

For comparison, here‘s how long it typically takes to reach various ranks:

Rank 10 = 3 hours
Rank 15 = 8 hours
Rank 20 = 12 hours
Rank 30 = 24 hours

So expect around 10 hours of in-game time to reach level 18. Fortunately, there are several strategies to accelerate XP gain:

Leverage Double XP events – Periodic 2XP events double all XP earned from matches, kills, challenges, etc.
Play objective modes – Modes like Domination provide lots of opportunities for kills, objective score, and scorestreaks.
Use Hardline – Perk provides bonus XP for kills assisting in leveling quicker.
Activate XP Tokens – Earn 1 hour tokens each rank up for a quick boost.

Once Rank 18 is reached, the Lachmann-762 assault rifle will unlock.

Step 2: Level Up the Lachmann-762 to Rank 13

With the 762 unlocked, next you need to reach level 13 by earning weapon XP. The fastest ways to level up a weapon include:

Maximize weapon use – Create loadouts focused around the 762 to get the most kills with it equipped.
Leverage small maps – The 762 excels on close quarters maps like Shoot House and Shipment.
Go for longshots – Earn bonus XP by getting longshot medals with ARs.
Use XP tokens – Tokens boost weapon XP gains for faster leveling.

Helpful loadout tips for the 762:

Attachments like extended mags improve ammo capacity for streaks.
Optics enhance ranged accuracy for mixed gunfights.
Quick response barrel boosts ADS speed.

Getting the Lachmann-762 to level 13 will unlock the Lachmann-556 AR.

Step 3: Level the Lachmann-556 to Rank 12

One final weapon to level before unlocking the Lachmann Sub. Use the same strategies of maximizing use, tokens, longshots, and small maps to get the 556 to level 12 efficiently.

556 loadout tips:

Prioritize ADS speed and movement attachments.
Pair with reflex optic to balance CQB and range.
Perks like Double Time and Lightweight improve mobility.

Once the Lachmann-556 reaches level 12, the Lachmann Sub SMG will be unlocked!

Unleash the Power of the Lachmann Sub

After grinding through 18 ranks and leveling up two assault rifles, the Lachmann Sub SMG will finally be yours. Immediately create a class to take advantage of its lightning fast TTK up close.

Recommended setups:

Laser and Collapsible Stock for sprint to fire speed.
50 round mags to delete groups and enable spray.
Quickdot LED sight for clean optic.
Perks like Double Time and Lightweight to further boost mobility.

Equipped properly, the Lachmann Sub absolutely dominates close quarters combat. Smgs naturally pair well with an aggressive, flanking playstyle.

Now that you have the deadliest CQB weapon unlocked, look to engage enemies within 12 meters where its blazing fire rate will melt anyone almost instantly. Clear out interior objectives and lockdown tight spaces to get the most from the Lachmann Sub.

Stick with it through the long unlock grind, and the Lachmann Sub will prove to be one of the most powerful tools in your Multiplayer arsenal. Use this guide to unlock it efficiently and start dominating close quarters engagements.
