And there's the two meanings that are relevant to how G28 gets ruled.

Also defense makes perfect sense if the defending alliance is already not going to get a CAPTURE and wants to deny a CAPTURE to the opponents. Or if the defending robot can't cross DEFENSE and can't even CHALLENGE, then denying even a CHALLENGE would be a net benefit.
