SLD or Simulated Life Doll
The SLDs were the first attempt to create an android - a manufactured organism whose systems and structures imitate human biology. An SLD breathes, eats, sweats and can feel pain. They aren't actually human so are more durable than their flesh and blood counterparts. The brain of an SLD is created from the patterns and engrams of a human brain, often forming a close bond or link between the SLD and its human "pattern."
SLDs are cutting edge technology and as such are closely monitored by the TCTF. There are very few of them and most are modeled after children because the smaller bodies are easier to create (and easier to control if they run amok) The TCTF is experimenting with using "adult" SLDs as field agents because of their exceptional strength and intelligence.
The Syndicate have also been experimenting with SLD technology, but their efforts have been progressing much more quickly without all the rigorous safeguards used by more respectable scientists. The Tankers are the result of this experimentation: super tough, super strong SLD warriors with a seriously bad attitude.
