When a unit is exhausted (e.g., after moving), does its attachment also become exhausted, or does the attachment remain ready?

Ruling: The exhausted/ready state of a unit does not affect the state of its attachments and vice versa. When a unit is exhausted, its attachments remain ready unless separately exhausted.

Nuances:

• Currently this distinction has no gameplay impact, so while players should be reminded of the correct procedure, it should not significantly impact their game at tournaments
• If a player exhausts both unit and attachment together when only the unit should be exhausted, this would technically be a general gameplay error that could be rewound, but enforcement should be lenient given the rule's current irrelevance
