- "9mm submachine gun with integrated sound suppressor and good recoil control."
— In-game description
The MP5SD is, function-wise, very similar to its other MP5 counterparts. It does have the benefit of having an integral suppressor, but not suffering from the attachment's damage penalty if the target is shot within 28 meters.
Overall, the submachine gun is suited for more close-quarters engagements, where its benefits shine.
