Disposal units are death machines employed in Skynet Work Camps to facilitate the systematic extermination of humanity. How they work is not known, but their efficiency is undoubted. These may be the "slaughterhouses" mentioned by Kyle Reese in "Dungeons & Dragons" of Sarah Connor Chronicles.
- Kyle Reese: "The disposal units ran night and day; we were that close to going out forever."
- It is likely that disposal unit refers to something analogous to the furnaces present in Nazi Death Camps during WWII. These "units" are responsible for the obliteration of millions upon millions of "unwanted" human remains.
