Dalek Killer
In the 26th century, Dalek Killers (otherwise known as DK's) were criminal citizens of the Earth Empire who were given a slim chance of having their death sentences of vaporisation commuted if they fought the Daleks, with miniscule odds of survival. The Earth Empire judicial authorities would offer, as an alternative to execution, the chance to choose from a wide variety of weapons prior to teleportation to a Dalek Empire planet where they would do their best to survive.
The Dalek Killers had only a slim chance of living with 600 million to one given as one estimate. Only a quarter of the criminals would even survive the experimental teleportation technique from the "Dee-Kay room". Of these, the survivors had an average life expectancy of just under two and a half hours. (DWM: Abslom Daak... Dalek Killer)
Those few who survived, however, could make money by selling bounty in the form of salvaged parts of Daleks such as gunsticks and eyesticks.
Abslom Daak was the most notorious Dalek Killer of all. Others included Máire, a contemporary of Daak's, who chose DK duty after her trial for political terrorism. After her return to Human space, Máire served as high priestess to a group of Travellers on the planet Heaven. (NA: Love and War)
