When you offer combat level, they will have the following benefits:
- Your ships will not attack theirs. They can still attack you unless they offer combat level, too.
- When you offer both combat and ship level, your Glory Devices will only do the reduced damage to their ships (1/10 mine hit for Saber, 1/20 for D19b).
- When you offer combat, vision and ship level, they will receive a copy of all your combat recordings (VCRs). VCRs you receive by this mechanism will not be forwarded, there is no double-forwarding of messages.
