The HK UMP45 is one of the two submachine guns. It is strong like an assault rifle but just a bit slower.
Despite the UMP's slow fire rate and reload speed. It is seen as an "overpowered" weapon, the damage evaluated as most assualt rifles. The accuracy is almost pin point with the combination of "auto" and "spam" (quick 3-round burst) fire rates. The UMP can get headshots and long range hits quite easily, especially in mid-large maps such as Turnpike and Riyadh.
The UMP isnt shown in much games, the only popular games shown with the UMP is the Call of Duty: Modern Warfare and also Counter Strike. In almost all games the UMP is seen as a very controllable yet powerful weapon.
