How to Unlock & Best Loadout

Modern Warfare 2 is out and had the best-selling opening weekend in the history of Call Of Duty. Millions are jumping in and grinding the game to unlock all its weapons and rewards in order to come out on top in all their multiplayer matches. Modern Warfare 2 and Warzone 2 feature many returning weapons like the M4 and also the MP5, which has curiously been renamed to the Lachmann Sub.

The Lachmann Sub is a Submachine Gun that performs exceptionally well from close to mid-range and has a super high DPS due to its high rate of fire. The gun also excels in mobility, handling, and recoil control, making it a perfect choice for aggressive players who prefer a run-and-gun play style. While this weapon will be desirable among most, the Lachmann Sub cannot be unlocked via traditional means, and you will have to progress through the Lachmann-762's weapon tree to access it. Here is how to unlock the Lachmann Sub and the best attachments to equip.

Updated by Nathan Round on November 29th, 2022: We've updated this post to include more loadout information that will be useful for both Modern Warfare 2 and Warzone 2 players.

Unlocking The Lachmann Sub

In order to unlock the Lachmann Sub in Modern Warfare 2, you must first fulfill the following prerequisites. Firstly, you will need to unlock the Lachmann-762, which is a Battle Rifle that is made available once you reach level 16. Next, you will need to get your Lachmann-762 to weapon level 13, and by doing so, you will be given access to the Lachmann-556 Assault Rifle. Now, all that is left is to get your Lachmann-556 to weapon level 12 to gain access to the Lachmann Sub. Leveling up your weapons is a pretty simple task, as all you need to do is use them in your matches and gain eliminations. But if you want to level up your weapons twice as fast, then keep looking for double weapon XP events in Modern Warfare 2.

Lachmann Submachine Gun Best Loadout

The attachments we have chosen for the Lachmann Sub will drastically improve its accuracy, as well as boost the range, damage, and recoil control. However, this is at the cost of a small amount of mobility. The XTEN RR-40 muzzle attachment is our first pick, which will boost the effective range of the Lachmann Sub, as well as keep you off enemy compasses whilst firing your weapon. This attachment will also smoothen out that recoil for added precision and allow your bullets to reach targets faster by upping the bullet velocity.

Next, go ahead and equip the FTAC TIGER GRIP and the LACHMANN TCG-10. Doing so will add more control to your recoil to improve those mid-range engagements. Hip fire accuracy is also increased, proving useful for times when you are caught by surprise and need to fire from the hip. The VLK LZR 7MW laser is also a must-have attachment because it will drastically increase your ADS and sprint-to-fire speeds. This is especially useful for an SMG class, as you will want to be as agile as possible. Getting your gun up faster will tailor this gun for a run-and-gun playstyle.

For the final attachment, we have chosen the 40-ROUND MAG. This attachment will boost your magazine ammo capacity from 30 to 40 rounds, making the gun more viable for racking up killstreaks in a single life. You can equip the 50-Round Drum magazine, but doing so will slow down your weapon significantly. We find that the 40-ROUND MAG provides a better balance for speed and holding more rounds in your gun.
