UMP45

The Heckler & Koch UMP45 is a Submachine Gun that appears in Call of Duty: Modern Warfare 2.

Singleplayer
In singleplayer, The UMP45 has a 25 round magazine, moderate recoil, and a low rate of fire. The player starts with a UMP45 in the campaign level The Hornet's Nest, and in the Special Ops level Big Brother. The player can also find UMP45's in several other Campaign and Special Ops levels, and are mainly used by Task Force 141, the Ultranationalists, and Shadow Company.

Multiplayer
In multiplayer, the UMP45 is unlocked by default. It is considered to be one of the best overall firearms. Compared to other SMGs, the UMP has moderate recoil, a comparatively low rate of fire, and kills in a maximum of 3 shots regardless of perks or attachments. The UMP only benefits from Stopping Power at close range, where the perk reduces shots required to 2. This 2 hit kill range only reaches as far as typical shotgun range. Long range shots will deal 49 damage each, thus still requiring 3 shots for a kill.

It is generally advisable to use this weapon in conjunction with a Silencer, as it provides no damage reduction. However the iron sights are unfavorable to some as they take up a large portion of the lower screen (while only providing a very short sight base), and due to the slight vertical recoil and muzzle flash, it may be difficult to track targets. For this reason players may choose the Bling perk to add an optic, especially the Holographic Sight or ACOG. While having lower recoil than most SMGs, it has relatively higher recoil than most assault rifles, and the UMP blurs the line between the two weapon types. When firing at targets at long range, it is advisable to fire off single shots or 2-round bursts by tapping the trigger. This weapon is favored in stealth builds due to its silenced versatility at all ranges without the need for Stopping Power. Some players find it easy to get headshots with the UMP45, as its recoil will cause the sights to rise to the head when aiming at an enemy's center mass.

The UMP is very effective in Hardcore, where it can deal one-shot kills at any distance unless the player is behind cover, has the Last Stand perk or the Final Stand/Painkiller deathstreaks. Because of this, a player could combine a thermal scope and a silencer and use it like an automatic, suppressed sniper rifle.

A popular tactic, both in hardcore and normal games, is to combine a silenced UMP with Marathon, Lightweight, and either Steady Aim, Ninja or Commando. This provides an effective sprinting class that will be able to maintain high damage (and thus reliability), notable speed, and the ability to rival shotguns and knives in close-quarters or to sneak past heartbeat sensors and sound-wary players.

Trivia

 * An unused piccatiny rail is present on the left of the gun. As well as being realistic - the same goes for the P90 - hinting that the heartbeat sensor may have been planned to be usable on Submachine guns.


 * Strangely, the UMP's first-person model has aspects reversed. The ejector port and selector switch are both on the left side of the gun.
 * Like the G36C in CoD4 and the P90 in both Modern Warfare games, the magazine has a clear section in the side but the level of load shown is always the same, regardless of how full the players magazine actualy is.
 * When a red-dot or holographic sight is attatched the fore part of the iron sights is removed.
 * The unusually high damage of the UMP is maybe because of the fact that the UMP uses the .45 ACP round,which is an effective one-shot stopper.The .45 ACP is also subsonic on its standard military loading(230 grains,muzzle velocity is less than 1000 ft/s),which may explain why putting on Suppressor Attachment doesn't reduce any damage whatsoever.
