UMP45

The UMP45 is a submachine gun featured in Call of Duty: Modern Warfare 2, Call of Duty: Modern Warfare 3 and Call of Duty Online. It is set to appear in Call of Duty: Ghosts.

Campaign
The UMP45 is heavily used by the Spetsnaz and moderately used by Shadow Company. It is also a randomly generated weapon for Task Force 141 members and is a starting weapon in "The Hornet's Nest" used by Gary "Roach" Sanderson with an ACOG Scope. It is also the starting weapon used by the player on the ground during the Special Ops mission "Big Brother".

Multiplayer
The UMP45 is immediately available from the start of the game in the First Recon class, and is available for Create-A-Class from level 4 onwards.

With user friendly iron sights, optics on this weapon are of questionable use. The UMP45's naturally high minimum damage allows for three-hit kills regardless of range, this attribute combined with Cold Blooded and a Silencer makes the UMP45 ideal for those who prefer a stealthier approach. The UMP45 is also a good candidate to combine with Hardline for a killstreak deployer (while using team-benefiting streaks such as UAVs and Counter UAVs). It is also popular for Rushing with Marathon and Lightweight. The UMP already has a high damage stat but adding Stopping Power can aid in close-quarter combat lethality by making the weapon a two-hit-kill, it can also do so out to longer ranges if a headshot is scored. The UMP45 also has higher penetration than all the other SMGs, comparable to Assault Rifles and LMGs. It is noteworthy that when the player does not use Stopping Power, Silencer gives practically no penalty, as it will take three hits to kill regardless, with the benefit of stealth and no muzzle flash.

The UMP45 is also the only SMG to consistently one-hit-kill in Hardcore (except if the enemy is using Last Stand, Final Stand or Painkiller, or when firing through cover), which makes it a great gun to take on groups of enemies.

The UMP45's lower rate of fire is its primary weakness, as it has the third-lowest fire rate of all fully automatic weapons in game. At closer ranges, the UMP45 can be overwhelmed by weapons with faster fire rates, such as the MP5K, although this slower rate of fire can be useful for ammunition conservation. However, the low fire rate can be easily solved with the Rapid Fire attachment. Some players prefer to use Bling in order to have Rapid Fire to compensate for the low rate of fire and the attachment they desire. It should be noted that Rapid Fire reduces centerspeed and will provide less time for recoil to settle and increase effective recoil, making the weapon more difficult to use at longer distances.

The UMP45 can be an effective counter sniper weapon with the ACOG Scope in Hardcore. The slow rate of fire combined with its high damage makes it a good choice for long range encounters, and, as it is primarily a close-quarter combat weapon it is also decent at close range, especially with Steady Aim.

Call of Duty: Modern Warfare 3
The UMP45 returns in Call of Duty: Modern Warfare 3. It was first shown in the reveal trailer for the game, as a soldier was blind firing it.

Campaign
The UMP45 appears in Call of Duty: Modern Warfare 3's Campaign. It is seen in the level "Mind the Gap" by the Ultranationalists. "Stronghold" while the Yuri and Price are clearing the prison cells of enemies and after it goes loud. It is in the large room where the shootout is with an office on the far right side. It is in that office. The UMP45 is usable and can be picked up by the player. It uses the same model as in ''Call of Duty: Modern Warfare 2. It also features Modern Warfare 2's ''ACOG Scope. This is the only time the UMP45 is usable in the game.

Multiplayer
The UMP45 appears in Call of Duty: Modern Warfare 3 ' s multi-player. It is available in one of the five default classes (First Recon). It features a 32-round magazine, moderate recoil and clear iron sights. The UMP45 has much lower damage at range than its Call of Duty: Modern Warfare 2 counterpart, killing in six shots (before a recent patch) outside effective range. It does, however, have a faster rate of fire, lower recoil, higher maximum damage making it a two-shot kill at close-range if one of those shots is a headshot and features the higher penetration of assault rifles, making it ideal for close-quarters combat and room clearing. The UMP45 also has the highest range of all the SMGs so it's quite effective at medium ranges too. Rapid Fire is a popular and effective attachment online, especially in conjunction with a Silencer, particularly in Search and Destroy where the limited amount of enemy players makes up for the rapid ammunition consumption.

Infinity Ward has released a hotfix that buffed the UMP45's minimum damage to a five-shot kill, therefore it is now much more effective at medium range than it was prior to the update and is now on par with the MP5.

Survival Mode
The UMP45 is available in Survival Mode at level 4 and costs $2000. The UMP45 is a versatile weapon due to its high damage in close range and relatively higher mobility comparing to the assault rifles which have similar amount of damages; for example, a magazine of bullets is enough to take out a Juggernaut much like the CM901. The gun also has a relatively clear iron sights, which means an optic attachment is not necessary. Moreover, the slower rate of fire compared to other submachine guns reduces the problem of recoil, which makes the gun more controllable. In short, this gun is an ideal weapon for close quarter combats maps. The UMP45 it is a fairly effective weapon against Little Birds.

 * In multiplayer, when a Red Dot Sight or Holographic Sight is attached, the front iron sight is removed. However in campaign and Spec Ops, this does not occur.
 * On Infinity Ward's official website, the UMP45 was voted the favorite submachine gun in Call of Duty: Modern Warfare 2.
 * Camouflage only appears on the stock and sides of the weapon (and is faded in comparison to other weapons), making it difficult to see unless reloading.
 * In campaign, this weapon's magazine holds 25 rounds compared to 32 in multiplayer, making it one of the few weapons that have a larger magazine capacity in multiplayer. Similar weapons include the Model 1887, SPAS-12, M93 Raffica, G18 and AUG HBAR.

 * In the mission "Stronghold" the Call of Duty: Modern Warfare 2 UMP45 appears, equipped with the Call of Duty: Modern Warfare 2 ACOG Scope. Like the L86 LSW in the same level, this seems to be a placeholder that was never replaced.
 * Call of Duty: Modern Warfare 2 model for the UMP45 also appears in the Special Ops missions Charges Set, and the Black Ice DLC.
 * The reticle of the Modern Warfare 2 ACOG scope in the mission "Stronghold" is slightly misalligned
