Under Taker (nicknamed "Umbrella Trashsweeper" or simply "UT") is the name of a humanoid Bio Organic Weapon. They are dispatched via helicopter to "clean up" any evidence of wrongdoings by Umbrella.
The Under Takers were created by Umbrella as a rapid-reaction force to counter t-Virus outbreaks due to the low-survival rate as expected with such missions. They were also given the added task of destroying evidence that could link Umbrella to the event, including the execution of witnesses. To ensure the complete removal of evidence, Under Takers were designed to dissolve once killed.
Under Takers were equipped with night vision scopes, black body armour similar to the ones used by the USS, and were armed with Heckler & Koch MP5s, some of which mounted laser sights so that they could snipe at enemies while concealed.
