UMP45

The UMP45 is a submachine gun featured in Call of Duty: Modern Warfare 2 and Call of Duty: Modern Warfare 3.

Single Player
The UMP45 is used heavily by the Russian forces. It is 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 Spec Ops mission "Big Brother".

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

With user friendly iron sights, optics on this weapon are of questionable use. The Silencer is a favorable attachment for the UMP45 as the weapon's naturally high minimum damage allows for 3-hit kills regardless of range. This attribute 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 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.

A lower rate of fire is the UMP45's primary weakness. At closer ranges the UMP45 can be overwhelmed by weapons with faster rates of fire, such as the MP5K. However, the slower rate of fire can be easily solved with the Rapid Fire attachment. Some players prefer to use Bling in order to have both Rapid Fire, plus another attachment of their choice. It should be noted that Rapid Fire will make less time for the recoil to settle down and thus increasing it, making it more difficult for long distance use.

Trivia

 * Like the G36C of Call of Duty 4 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 player's magazine actually is.
 * In multiplayer, when a Red Dot Sight or Holographic Sight is attached, the front iron sight is removed. However in single player, this is not the case.
 * On Infinity Ward's official website, the UMP45 was voted the favorite submachine gun in Modern Warfare 2.
 * Camouflage only appears on the stock and sides of the weapon, making it difficult to see at times.
 * In singleplayer, this weapon's magazine holds 25 compared to 32 in multiplayer, making it one of the few guns that have a larger magazine capacity in multiplayer. Similar weapons include the Model 1887, SPAS-12, M93 Raffica, G18 and AUG HBAR.
 * The UMP45 is the weapon featured in the picture for the attachment Akimbo.
