Good question! "Copy [that]" is actually short for "I copy that transmission," which was spoken over walkie-talkies to show that one has received and understood someone's previous communication. Now, it's often used casually to mean "I understand" or "understood." It's similar to the expression "Roger [that]." Ex: A: I think we need to get more gas. B: Roger that. Ex: A: Can you send over some extra supplies for the soldiers? B: Copy.
