I've heard the term "HardCat rules," but don't know what they are.
Hard Cat Rules Link which is the observations of the C2 link in CM found here Command Friction 2.0 & here C2 & Information Sharing (REDUX) Which Bil Hardenberger & @A Canadian Cat came up with (hence the name) here's their AAR CMSF 2 - Co-op AAR (Bil v IanL) Using Realism Rules
Try it out on a small single player mission, it really enhances the game.
Don't worry if it's not been used in this experiment.
