UMP45

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

Singleplayer
The UMP45 is used heavily by the Russian forces. It is moderately used by Shadow Company. It is also a randomly generated weapon for TF141 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. It is one of the few guns to have a higher magazine capacity in Multiplayer rather than Singleplayer.

Multiplayer
The UMP45 is unlocked at level 1, available in the "First Recon" Default Class. Combined with its moderate rate of fire, decent recoil, and high damage output with little damage drop, it is a very powerful, very popular weapon.

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.

It can be used in conjunction with Cold-Blooded and Ninja for a stealth class. The UMP45 is also a good candidate to combine with Hardline for a "team-player" 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 is also the only SMG to consistently one-hit-kill targets in Hardcore. But the one-hit-kill ability only applies when enemies are not using Last Stand, Final Stand or Painkiller.

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 increase the UMP45's recoil, making it more difficult for long distance use. Red Dot Sights and Holographic Sights are recommended for longer range kills.

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.
 * The UMP45 is very similar to the MP40 in Call of Duty: World at War, both being widely used, high powered SMGs with a low rate of fire and 32 rounds per magazine.
 * Camouflage only appears on the stock and sides of the weapon, making it difficult to see at times.
 * The UMP45 does more minimum damage than most assault rifles and light machine guns, despite its SMG status. Although it is weakened by its comparatively lower rate of fire, it still has an equal or greater killing speed than assault rifles like the SCAR-H, ACR, and M4A1.
 * In singleplayer, this weapon's magazine holds 25 compared to 32 in multiplayer, making it a somewhat rare occurrence. Similar weapons include the Model 1887, SPAS-12, M93 Raffica, G18 and AUG HBAR.
 * The UMP45 is tied with the SCAR-H for the second lowest rate of fire for all fully automatic weapons in Modern Warfare 2's multiplayer. The automatic weapon with the lowest rate of fire is the AA-12.
 * This and the MP5K are the first submachine guns to be unlocked.
