The UMP45 (German: Universale Mashinepistole 45, English: Universal Machine Pistol 45/Universal Submachine Gun 45) is a submachine gun developed by Heckler & Koch. It is part of the UMP family of weapons, which were designed as cheaper, modernized alternatives to the HK MP5. As it's name suggests, the UMP45 is chambered for the larger .45 ACP cartridge as opposed to the 9×19mm cartridge utilized by the MP5, although another member of the UMP family, the UMP9, is also chambered for 9×19mm.

In Insurgency, the UMP-45 is the big brother to the MP5K. The UMP-45 fires a larger round that deals more damage than the MP5K, but suffers from greater recoil and a slower rate of fire of 600 RPM. This makes the UMP-45 more suitable for close-mid range combat.
- The UMP-45 is considered the Security faction's counter to the MP40 due to their slow rates of fire.
- In reality, the UMP-45's foregrip can be removable, as it is a standard grip attached to a picatinny rail. However, the UMP in-game has it permanently attached.
- There is an alternative dry reload animation for download on the Steam workshop, it replaces the standard HK Slap with a simplistic pull of the bolt. For gameplay reasons, both reloads require the same time to finish. However, it is unrealistic to a certain degree, as the 'HK slap' is actually recommended procedure; a softer approach might not drive the bolt home properly, and could even result in a feed failure.
