Call of Duty: Iron Wolf
"The UMP.45 fits the all-purpose niche of the SMG category. With no glaring weaknesses unmodified, it is still trumped by more extreme weapons. Fitting well with most strategies, it will offer an edge in every form of battle."

- In-game description The UMP.45 appears as a submachine gun. It is chambered for the .45 ACP caliber.

Campaign
The UMP.45 is an enemy weapon primarily appearing in the 2023 timeline missions including; Sagitarrio, Legends Never Die, Act of Valor, Cedo Nulli, Grieving Wolfpack and The Last Predator. The latter three are of the 2033 timeline.

Multiplayer
The UMP.45 is unlocked by default alongside the MP5 and is frequently compared. While the MP5's higher fire rate and higher recoil make it better suited for close range, the UMP.45 will be the winner in medium ranged skirmishes. Players tend to favor it due to its lower controllable fire rate and the ability to kill in the same number of shots. However, the low fire rate means that it performs less effective than its older counterpart in closer range fights. This is one of the weapon's biggest weaknesses, although it seldom is a problem if used correctly.

As of always, the Silencer is a highly used attachment, however it does somewhat decrease its effective range well below the MP5 when it is equipped with one as well. Since it has clear iron sights, an optical attachment isn't a necessity, however equipping an ACOG scope will increase its overall effective range, which is handy with a Silencer. The Over-gassed Action is an interesting choice, buffing the fire rate up to nearly the Skorpion EVO's standard. With the higher damage, it can be used almost as a moderately ranged Skorpion EVO with higher damage.

The UMP.45 is one of three submachine guns that can accept the Long Barrel attachment. The other two are the Skorpion EVO and SIG MPX.
