=== Terminology ===
The term "chest unit" is used on-screen in The Moonbase, Revenge of the Cybermen, Earthshock and World Enough and Time, all referring to Cyber-subspecies first seen in the classic series.
Doctor Who Files 8: The Cybermen, a non-narrative source, contains a rare use of "chest unit" in reference to new series Cybermen. Specifically, it identifies the chest unit of a Cyberman made by Cybus Industries.
=== Hybrids ===
During the gap between the broadcasts of The Invasion and Revenge of the Cybermen, a number of hybrid Cyber-suits were crafted out of existing Cyberman parts for publicity purposes.http://www.themindrobber.co.uk/mystery-sixties-cyberman.html
