IMFDB notes that the MSMC and the PDW-57 are the only SMGs that can achieve a 3-hit kill at close range in multiplayer. Described by the Call of Duty wiki as a 'medium capacity, high damage and ranged submachine gun,' it does the most damage at close range out of any gun in its class. The MSMC is used by the Cordis Die mercenary faction in Call of Duty: Black Ops 2. As the COD Wiki points out, this means switching to the M16A4 is almost as fast as switching to a handgun, but with more 'killing power.' The M16A4 is pictured here in a promotional image during the mission 'War Pig.' The M16A4 can be fitted with a silencer, red dot sight, ACOG scope, and M203 grenade launcher in multiplayer. It's especially effective at long ranges. In multiplayer, it has a three-round burst, which is more accurate.

According to IMFDB, it (incorrectly) fires fully automatic in single-player. Similar to the UMP45, an assortment of attachments are available for this weapon. To compensate, the FAMAS has a rate of fire of 937 RPM. In multiplayer, it has a lower damage per bullet and lower range than other assault rifles in the game, the COD Wiki says. It has a 30-round magazine (45 with extended mags). The fully automatic FAMAS is seen in later Call of Duty: Black Ops missions. It's also used by the multinational unit Task Force 141. It's used by the Russian Spetsnaz (special operations) group, as well as the private military unit Shadow Company. It also has a high damage output which isn't negatively affected by attachments like extended mags, a silencer and more. According to the Call of Duty Wiki, it features a 25 (campaign) or 32-round (multiplayer) magazine, light to moderate recoil and user-friendly iron sights.

The powerful and accurate UMP45 submachine gun can do some serious damage. It is pictured here with a grenade launcher attachment. In multiplayer mode, it can be customized with a red dot sight, silencer and ACOG scope, according to the Call of Duty Wiki. In campaign mode, this gun is used by the Russian Ultranationalist organization and the Middle Eastern antagonist group OpFor. Effective as a close and medium-range weapon, the AK-74u is classified as a submachine gun in COD 4: Modern Warfare, but as IMFDB points out, it penetrates walls and other cover like other assault rifles, something other SMGs in the game can't do.
