UMP

The UMP .45 (Universale Maschinenpistole, German for "Universal Machine Pistol") is a submachine gun developed and manufactured by Heckler & Koch used in the Battlefield series. The UMP is a blowback-operated, magazine-fed submachine gun firing from a closed bolt. As originally designed, the UMP is chambered for larger cartridges than other submachine guns like the MP5, to provide more stopping power against unarmored targets (with a slightly lower effective range) than the 9x19mm MP5 provides. A larger cartridge produces more recoil, and makes control more difficult in fully automatic firing. To mitigate this, the cyclic rate of fire was reduced to 650 rounds/min (600 rounds/min for the UMP45), which makes it one of the slower firing submachine guns on the market.

Battlefield 2: Modern Combat
The UMP .45 is featured as the main weapon of the EU's Spec Ops Kit. It has decent accuracy, a high fire rate, and moderate damage.

Battlefield: Bad Company
In Battlefield: Bad Companys multiplayer, the UMP' is issued to the Specialist kit as an unlockable costing one unlock credit. It has 60-round magazine and 180 rounds in reserve, as with all Specialist-exclusive weapons. It has a has a moderate rate of fire, high damage and mediocre accuracy, however, compared to the other compact assault rifles in the game, it has the lowest rate of fire, the highest damage per bullet and the highest accuracy.

There is a UMP Trophy and is unlocked by achieving 6 kills with the UMP in one game. This trophy when awarded, is usually accompanied by the "Compact Assault Rifle Efficiency" Trophy.

UMP-45
Only available in multiplayer, the UMP-45 is the 7th and last submachine gun issued to the Engineer kit requiring 43000 experience points to unlock. It has a 25-round magazine, low recoil, decent damage and good accuracy. Compared to the other SMGs, it has higher power and higher accuracy, which is advantageous at longer ranges, but its lower rate of fire is a nuisance in close quarters. It can use a Red dot sight and 4X Rifle Scope.

While the weapon does have arguably obstructive iron sights, the lack of recoil and muzzle flash can reduce the need for a red dot sight at close range.

It has exactly the same damage and rate of fire as the SCAR-L Carbine, but trades 5 rounds for less recoil. Players may face a dilemma when choosing the better submachine gun of the two.

UMP-45 SA
The UMP-45 SA is also available to those who purchased the SPECACT DLC on Xbox at 160 Microsoft Points or PS3 at $1.99. It is the UMP-45 customized with either Desert, Woodland, or Arctic camouflage depending on what environment the player is in. The SPECACT DLC has been released as downloadable content for the PC on 1 December via the EA Store.

UMP45
In Battlefield Play4Free, the UMP45 is a buyable Elite submachine gun for the Engineer kit. With a 35-round magazine, many would see this weapon useless compared to the Veteran's or Elite's MP7's as they both have the same amount of ammunition per magazine and nearly the same damage, with the Elite's MP7 surpassing the UMP45. However, the UMP45 has better damage at longer ranges, making it more suitable as a sort of compact assault rifle when compared to the MP7 or even the FN P90. Unfortunately, the price for the UMP45 is quite high at up to 980 for the price of low recoil and higher damage at range.

When using the UMP45, short busts are necessary for it to perform best at medium to long ranges, while it can be fired fully automatically up close for maximum damage potential as it has a decent spread for hip fire. Despite being an Elite weapon, the UMP45 has an all-black paint scheme, much like the Medic's M249 SAW.

Holosight UMP45
The Holosight UMP45 is nearly identical to the standard UMP45, but it is equipped with a custom Holographic Sight for better target acquisition at range over its standard iron sights. The weapon performs the same as the original UMP45, but the user can pull up the sights to fire down range more accurately faster than the default UMP45, making it better suited for medium or even long ranges combat. The weapon is completely separate from the default UMP45 and costs 150 for one day, 525  for thirty days, and 1050  for unlimited use.

Battlefield 3
The UMP-45 was listed on the four page fact sheet released by EA at Gamescom.

Trivia

 * There are complaints about the UMP in Battlefield: Bad Company, as many players of the game view it as 'overpowered' due to its high damage output and accuracy.
 * The magazine on the UMP in Battlefield: Bad Company is visibly longer than its counterpart in Battlefield: Bad Company 2. Possibly due to the 60 round capacity in the former.
