There is strong evidence Bruce Rea Taylor built on his earlier rules, Challenger and Firefly, when developing the Corp/Korps Commander Rules. This is especially evident in the equipment specification. Players in the last 20 years have used these earlier rules to expand Corps/Korps Commander, such as can be seen in the "nikita - Corps Commander: OMG and Korps Kommander" site referenced earlier, and attempts to rewrite the rules as can be seen with Korps-Kommandeur.
