This category contains characters who left the government to which they were initially loyal and offered their services to another government, usually but not always the enemy of their previous allegiance. Characters who were defectors in OTL may not have been defectors in the Harry Turtledove timeline in which they appear, and vice versa.

NOTE: Several of these characters were killed or captured while attempting to defect and never had the opportunity to offer their services to an enemy government. They are included here nonetheless because their intention was to become defectors.
